FAQs




Functionality


No, the LFC is mixing the new waste food with the old waste food and the Powerzymes (microorganisms).

The waste food is decomposed and primarily produces water, CO2, and heat.

If waste food is chopped or ground, small parts of undigested food will enter the exit stream, increasing the levels of TSS (total suspended solids) and BOD (biological oxygen demand).

The motor on the LFC acts only to mix, or slowly stir, the waste. It runs only a quarter of the time, which minimizes the use of electricity.

No waste food can be added at any time. The machine is constantly digesting the waste.
No. The decomposition is an aerobic process (in the presence of oxygen). When leaves fall from trees in the forest and decompose in an aerobic manner, there’s no smell. This decomposition process is the same as the LFC uses, except it’s accelerated significantly.
Waste food only has a bad smell if it’s been left for some time to rot anaerobically (in the absence of oxygen). We recommend that waste food be placed in the LFC at intervals between 30 and 60 minutes, so there’s no time for the waste to start to smell.

If the waste has started to rot and is smelly, the aerobic decomposition will take over shortly after the waste is put into the LFC. This will then reduce or eliminate the smells.

No. The motor in LFC turns the food only for a quarter of the time. The rest of the time there is little source of noise. We use a large motor that operates quietly because it’s never under stress. Our clients tell us that the last thing you hear in their kitchen is the LFC!
The LFC decomposes most waste foods in 12 hours. Within 24 hours, 97% of the waste food is decomposed.
No. Each machine digests its rated capacity in the same time. For example, if you put 50 kg of waste into an LFC-50 and put 1000 kg of the same type of waste into an LFC-1000 the machines would digest these amounts in the same time.
The LFC has a microprocessor that optimizes the decomposition process. The LFC keeps the waste food moist, but not too wet. The LFC allows the waste food to generate significant heat for 75% of the cycle. Our proprietary blend of microorganisms and enzymes — called Powerzyme —causes the decomposition to take place as fast as possible.

Finally, we use a proprietary method to create our Powerchips. These Powerchips remain in the drum at all times and are very porous.

They house the microorganisms and rapidly disperse them among the waste food.

Powerzyme is a proprietary mix of microorganisms and enzymes designed to rapidly decompose organic food waste.
Powerzyme is safe to touch and / or inhale. The Powerzyme is non-toxic and non-hazardous.
You don’t need to take any special precautions if you accidentally spill it.
Oxygen is added each time you add waste food. It’s also present in the water that is injected into the drum.
They exit the LFC as nutrient rich grey water. This can be directed straight down the drain, into the sewage system.
No. The output of the LFC must flow to a sewer drain. This is usually a floor level drain that is commonly found in commercial kitchens.
Possibly. If you feed the machine with only waste from the preparation of fruits and vegetables, then what comes out of the LFC could be used to irrigate the land. The EPA should approve all land applications prior to land application. You should test the output first. In any case, you need to filter the output before you can use it.

It’s rich in nutrients just as if you had composted the waste food in a more traditional manner – this would make an ideal fertilizer. However, if the waste food has meats, fats, grease, and spices such as salt and peppers, the output may not be suitable.




Weighing the waste food


On each corner of the LFC there are load cells. These weigh the total weight of the LFC. On installation the software calibrates itself so it knows the empty weight. From there, the LFC software knows how much is in there and how much is added each time.

If waste food is chopped or ground, small parts of undigested food will enter the exit stream, increasing the levels of TSS (total suspended solids) and BOD (biological oxygen demand).

The motor on the LFC acts only to mix, or slowly stir, the waste. It runs only a quarter of the time, which minimizes the use of electricity.

The LFC reports when it’s safe to add more waste food. It does this with text on the touch screen and with an LED (green means ok; yellow means wait, and red means overloaded).
You can see the amount of waste that is ingested by the hour, day, week, month, and year. This is also converted by the LFC to report the amount of CO2 equivalent that is diverted from the landfill.
On an LFC that is properly installed and calibrated, the results are better than ±1% accuracy. Even the largest LFC (the LFC-1000) can detect something as small as an orange is added to the drum.
The LFC stores the data for 24 months.
Yes. See the section below for more details



Installation


The LFC should be installed in your kitchen. This is where the majority of waste food is accumulated and is therefore more convenient to easily dispose of the waste food.
The typical machine is the size of a desk or a chest freezer. You may find that you remove large buckets of waste food that you accumulate during the day because the waste food now goes directly into the machine. When you get rid of these buckets, you’ll have plenty of room for the LFC.
We don’t recommend it. If you need to install it outside, it must be under a cover and protected from the elements (including rain, dirt and snow).
The LFC must also be in a location that doesn’t get hot. The maximum ambient air temperature is 35°C.
You need hot and cold water (or only hot water or only cold water), a floor drain, and electricity. The LFC-50, LFC-70, and LFC-100 use single-phase power, the larger machines use three-phase power.
Three phase motors are more efficient, generate less heat and noise, and last longer. The LFC-200 is available in single phase 230 V, but it’s normally supplied in 3-phase. The larger LFCs are exclusively available in 3-phase.
No. For an LFC-200, they cost about a dollar a day. Smaller machines are less and larger machines are more.

The maximum amounts of water and electricity used are listed on our web site. In practice, the amount of water and electricity consumed are typically 80% of those values listed in the table.

The output of the LFC is at the bottom of the machine, 200 mm above the floor. The output isn’t pumped – it flows out with gravity. If the drain is higher than the output, you need to connect a sump pump to the output. This will take the output and pump it higher. These pumps are small and low cost. Full details are provided in our User’s Manual.

You may in some council areas connect the discharge via a Tundish close to the unit which is mounted on the wall.

Weigh the waste every day and make a record of it. Alternatively, weigh the waste food on Saturday, Monday, and Wednesday if you can’t weigh it every day for a week. Then calculate an average.

The capacity of an LFC machine is based on the duration of your working day. If you add the same amount of waste food at regular intervals over an 18 hour day you’ll need a smaller machine than if you dispose of the same amount of waste food over an eight hour day.

Yes. Buy some extra Powerchips to fill the extra space. Remove these as the amount of your waste food increases. You need the amount of waste food and Powerchips to be above the shaft of the arm inside the LFC.
Usually, a few hours. However, if you need to run power and water to the location, it may take longer.
Yes, we have arrangements with local service companies throughout Australia and New Zealand.
The grey water that is discharged is simply that – it’s passed through a mesh with holes that are just smaller than 1 mm there is no solid in there.

This is more environmentally friendly than a commercial dishwasher, which may have waste food from plates going down the drain untreated.

This grey water contains nutrients and microorganisms that will continue to digest any waste it encounters on its way. After a while the pipes are cleaner than before.
No. On the contrary, the grey water discharged from the LFC contains microorganisms that will digest the grease that is in the trap. The grey water contains very little grease or fat because this is digested inside the machine.

Although the use of the LFC will not obviate the need to clean the grease trap, it should increase the time between the cleanings.

The grey water flowing to the sewer is beneficial to the environment and to the processing of sewerage. The grey water contains microorganisms and mostly (97%) processed waste food. Unprocessed waste food and chemicals from the dishwasher are a much bigger problem.
Depends whether you discharge to local Trade Waste Infrastructure in which case you will need to add the LFC to your existing permit to discharge to Trade Waste as you do for any new or additional kitchen appliance.
If you have your own on-site treatment system you do not need any such permit.
Yes, we have designed our LFCs for use globally. Our three smaller machines support 240 V single phase and the four larger LFCs require 415 V three phase. The voltages are listed on our web site. Scroll down to Sizes, and click on USA Units or ROW Units.
No. All motors are ac. The larger motors are 3-phase.



Purchase


Power Knot Australasia ships from Silicon Valley Milpitas California.
New machines come with the correct amount of Powerzyme (microorganisms) and Powerchips (bio-chips). You shouldn’t need any more Powerzyme for about nine months and you don’t need to replace the Powerchips for about four years.
Third Party lease arrangements can be organised directly between the end user and a lease finance organisation.



Daily Usage


Yes. You don’t need to adjust the control panel in normal usage.
The machine operates continuously and you add waste food at any time. You can feed the machine 24 hours a day, 7 days a week. However, we recommend you add waste food no more frequently than every 30 minutes. This allows the machine adequate time to start the digestion of the last batch.
No. The maximum you can load is 80% of the rated capacity. We recommend that you usually add no more than 70% of the capacity. If your process permits only being able to add waste in one batch, buy a larger machine.

For example, if you want to dispose of 200 kg per day in a single batch, buy an LFC-300 (with a capacity of 300 kg). 70% of 300 kg is 210 kg so this can go into the machine once per day.

Anything that can go in your stomach can go into the LFC. The Powerzyme is designed to digest a mixture of waste foods comprising fruit, vegetables, cheese, breads, fish, and meat. Chop larger items like the heads of pineapple, and watermelons, as digestion will occur at a faster rate. Power Knot has a special blend of microorganisms designed specifically to digest waste fish.
The following organic materials cannot be fed into the machine: shells such as oyster and mussel, corn husks, large bones, nuts such as those from avocado and peach, and oils. Food that’s oily is okay to go into the machine — you just cannot pour liquid oil into the machine.

The following inorganic materials cannot be fed into the machine: paper, china, glass, plastic, rubber, cutlery, and any chemicals. You must also minimize organic materials that are very fibrous, such as corn husks (but corn cobs are ok) and lemon grass.

No. This will cause the temperature inside the machine to drop and that will slow the decomposition significantly. Let any frozen foods thaw thoroughly to room temperature before adding them to the LFC.
No. Wait until the food cools to about 45°C before you put it into the LFC. If the waste is too hot, it will kill the microorganisms.
The LFC will digest the meat, fish, and small bones, leaving only large fish bones or large meat bones. In time, even those bones will be digested, but if you put too many large bones into the LFC, the drum will fill with these bones.

The bones may become stuck between the arms and the drum causing the LFC to stop. These bones will take up space and reduce the amount of food that can be digested in a given time.

You can take the bones out after the meat has been eaten. But it’s better to cut the large meat pieces into chunks no more than 500 grams, so there’s a larger surface area for the microorganisms to digest.

On a regular basis, bones that are smaller in diameter than 2.5 mm are ok. Items larger than this are ok if they go in infrequently. For example, 50 fish heads a day into an LFC-1000 would be ok. But if you have many large bones you should avoid putting them in the LFC and dispose of them in a different way.
Yes. If it can go into your stomach, it can go in the LFC.
All the LFC machines up to the LFC 500 are designed to be loaded by hand. The LFC 1000 and bigger are fitted with a bin tipper.
We recommend that in your kitchen or food preparation area that you use 20 litre buckets to hold the waste food.

This size of bucket can be lifted easily and emptied into the LFC. In current practice, you may be using 200 litre buckets in the kitchen and empty that into an outside trash container only when it is full.

The slight change in operating procedure will result in a cleaner and less smelly kitchen and reduce injuries that may happen by moving a bucket containing 200 kg of waste.

Water is used to maintain the moisture content of the waste food as it decomposes. All microorganisms need water to survive. Our LFCs are controlled by a microprocessor to optimize the process and minimize the amount of energy and water required.

The default cycle is 20 minutes. For our LFC-200 (which can process up to 350 kg of waste food per day), the machine sprays hot water onto the waste food for 40 seconds at the start of each cycle. This uses about 4 litres water per cycle.

During each cycle, the machine uses cold water to wash out the cavity. This uses about the same amount of water. So, in a day this machine uses about 520 litres of water. The larger LFC units will use more water and the smaller LFC will use less.

The default program can be modified to optimize for water temperature, pressure, type of waste food, desired pH level of output, and acceptable concentrations of BOD, TDS, TSS, and COD of the waste water.

Keep the outside of the LFC clean as you would with any stainless steel item in your kitchen. Wipe the surfaces daily with a damp cloth.

Don’t use soaps or detergents as they may enter the drum and kill the microorganisms. The LFC isn’t designed to be soaked with a sponge or a hosepipe.

In the normal course you don’t need to clean or empty the inside of the LFC of use. The inside remains sanitary because the microorganisms are digesting any waste food they can.

You do need to replace the Powerchips periodically as explained here and that might be the only time you clean out the machine.

Yes, but there are products that claim to be “bio-degradable” that don’t decompose on the landfill, in a compost pile, or in the LFC.

We have tested several brands of biodegradable plates and cups. The majority of these items disappeared in minutes, but some leave a residue that takes a long time to decompose. Knives and forks don’t decompose.

Yes, the microorganisms need waste food to survive. If they don’t get food for 10 days they may die and then need to be replaced before waste food is again added.

For any machine, we recommend it should have no less than 10% of its maximum rated capacity of waste food per day. Leaving the machine without food over a long weekend is acceptable.

The microorganisms may die if they don’t have food for about 10 days. So, take a weekend off, but if you have a long holiday you may need to add more Powerzyme on your return.
No. Leave the machine running, even if you are away for two weeks.
Inside the LFC, all the electronics and the motor are protected against brownouts, blackouts, and surges. When the power is resumed, the LFC continues to operate and resumes its program cycle from where it was when power failed.

If the power fails for a short time (less than 10 minutes) this will have no effect on the operation of the LFC. If the power fails for a long time (longer than four hours) then the waste food in the drum is not mixed, water is not injected, and oxygen is not introduced.

This could turn the decomposition process form aerobic (in the presence of oxygen) to anaerobic (in the absence of oxygen). While the aerobic decomposition (the normal method inside the LFC) does not smell, the anaerobic decomposition does smell. Further, the process is slowed inside the drum of the machine so a user cannot add waste food to the machine at the same rate as when the machine is powered.

After power has been restored, the LFC will resume its cycle and will be working normally again after some time. That time will be at least as long as the power had failed. For example, if the power failed for five hours, then the LFC will be working normally again after a further five hours once the power is restored.

If the power fails for an extended period (longer than 36 hours) then the microorganisms may not recover and may need to be supplemented after power has been restored.

This will reintroduce the aerobic microorganisms that are prevalent in the Powerzyme. For the microorganisms to digest all the remaining waste food in the LFC the power shouldn’t fail for at least 24 hours.




Configuration and Data


The LFC has a colour touch screen with a modern user interface. Most customers don’t need to touch this screen: you can install the LFC, turn it on, and the default program works well.
Yes, a menu drives it that’s similar to a tablet or mobile phone.
Through the touch screen, you access all the configuration, control, status, usage data, statistics, and diagnostics.

All data about the amount of waste food ingested are available numerically and graphically.

The setup is all protected by a password. Clearing the data is all protected by a second password.



Remote Monitoring


The LFC has an ethernet port. You connect this to your LAN.

Once connected, the LFC will send its data to the cloud server.

Yes, we use 64-bit data encryption approved by Google.
No. The LFC must be connected to the internet.
You can connect the LFC to a Wi-Fi router, configured as a client. Or you can use a GSM (mobile phone) router.
The amount of data is small, about 100 bits/second. However, if you’ve been using the LFC for a while prior to connecting the LFC to the cloud, it will have much data to upload and until it’s completed, the usage of the bandwidth will be greater.
You can use any device that has a browser (such as Safari, Firefox, or Chrome). This means you can use any mobile phone, any tablet, or any PC. This includes any device that runs Apple iOS, Google Android, Microsoft Windows, or Linux.
You can see all data that is accessible from the touch screen. This includes the status and settings of the LFC, all statistics about usage and waste digested, and all diagnostics.
No. When you own the LFC this data is free.
The cloud server stores the last five years of data.
No. For security reasons, that’s not possible.
We use the Google Cloud services. You need an account with Google (which is free) and then you can access the data.
There is one administrator. That person can add five other people.



Operating Costs


The LFC uses water and electricity and has consumable items of Powerzyme and Powerchips.
No. For our largest machine (LFC-1000), the typical operating cost for electricity in the USA is under US$1400 per year.

When installed in a hotel, the electrical energy used by an LFC represents about 0.1% of the electricity used by the hotel.

No. For our largest machine (LFC-1000), the typical operating cost for water in the USA is under US$500 per year. When installed in a hotel, the water used by an LFC represents about 0.3% of the water used by the hotel.

In other countries please refer to the specification sheet for power usage for all sizes and your relevant power pricing structure.

You need to add more dry Powerzyme every three to four months and liquid Powerzyme every nine to 18 months, depending on usage.

Depending on the size of the LFC, that is about A$150 (for the LFC-50) to A$3,000 (for the LFC-1000) when using liquid Powerzyme.

You need to replace the Powerchips every three to five years. Depending on the size of the LFC, that is about A$650 (for the LFC-50) to A$13,000 (for the LFC-1000).

So, the average annualized cost of consumable items (after the initial items need replacing) is between A$500 (for the LFC-50) to A$10,000 (for the LFC-1000).

The LFC reports when it is time to service the LFC, including when to supplement the Powerzyme or replace the Powerchips.

You may be able to observe when these items need attention. The rate of digestion slows down when you need to supplement the Powerzyme or change the Powerchips. If the digestion has slowed and your Powerchips are less than three years old, supplement the Powerzyme.

If your Powerchips are over three years old and when you last supplemented the Powerzyme the rate of digestion was not fully restored, then change the Powerchips the next time you plan to supplement the Powerzyme.

For the dry (powder) Powerzyme, you just throw in the bag of microorganisms into the drum on the service schedule indicated by the LFC.

For the liquid Powerzyme, you should activate it for five hours in warm water and then gently pour it into the drum over the waste food.

The time to supplement the dry Powerzyme is two minutes. The labour time to supplement the liquid Powerzyme is 30 minutes.

Preferably, you should stop putting waste food into the drum 48 hours in advance of the change of the Powerchips. You then scoop them out or use an industrial wet and dry drum vacuum cleaner to remove them. You can recycle this plastic.

Once the drum is empty you pour the new Powerchips into the drum. The total time is between 10 minutes for the LFC-50 to 60 minutes for the LFC-1000.

No. These are consumable items and not covered under warranty. If you’ve purchased your LFC, Power Knot or its authorized service representative can supplement the Powerzyme or replace the Powerchips. This would be at your expense.
Power Knot’s offices and authorized resellers carry stock of these items.



Impact on the Environment


When the food was created, it used photosynthesis and CO2 from the atmosphere to grow. That CO2 is now released back to the environment. It’s a zero sum effect (referred to as the carbon cycle) and is perfectly natural – just like the leaves that decompose on the floor of a forest.
1 kg of dry organic matter creates only 0.44 kg of CO2. Waste food is typically 30% dry matter and 70% water. The 1 kg of wet organic matter creates only 0.13 kg of CO2.

The LFC-500, digesting 500 kg of waste per day will create only 66 kg of CO2 per day. At standard atmospheric pressure, this occupies a space of 42 litres. The rate of discharge is a mere1.75 litre per hour.

As a point of reference, the average adult when resting inhales (and exhales) 450 litres per hour of air. About 5% of that is oxygen that we have converted to CO2, so we typically output 23 litres of CO2 per hour.

The amount of CO2 created by the process is minimal. Because CO2 is heavier than air, it falls through the bottom of the drum.
No. The decomposition in the LFC is aerobic.
No. The decomposition takes place in a natural way using microorganisms. Microorganisms are around us everywhere and are responsible for digesting all types of waste.

We have a special blend of microorganisms (Powerzyme) that accelerate the decomposition of most foods. The LFC can decompose most waste foods within 24 hours.

No. The blend of microorganisms and enzymes is safe to touch and the vapour from it is safe to inhale.

The Powerzyme is non-toxic and non-hazardous. If you accidentally spill it, there are no special precautions you need to take.

All microorganisms used in the LFC are naturally occurring – none of them are genetically modified.

The Powerzyme complies with all applicable rules or orders under the Toxic Substances Control Act USA (TSCA) and doesn’t contain any chemical substance in violation of it or any applicable rule or order under it.

The LFC uses water to maintain the proper environment within the drum to speed decomposition. The LFC also uses water for the washout.

The sum of these is shown on the data sheet and our web site (but the amount of water can be adjusted depending on the moisture of the waste food).

This water all flows through to the output. The majority of the waste food is decomposed into water.

For example, 1 kg of water is converted to 1 litre. If you use an LFC-100, the default water usage is 250 litres per day. So if you put in 100 kg of waste food per day, this will be converted to 100 litres. The total water output from the machine is the sum of these = 350 litres.

This depends on the composition of the input. It’s not possible to give fixed numbers for BOD, FOG, TSS, and TDS. Look at Power Knot’s application note for more details on this topic
No, it’s 50 ppm to 1000 ppm (mg/l) depending on the type of food fed to the machine and when the output is sampled.

Over 97% of the material in the grey water is decomposed, but some solid material exits the machine through the fine mesh screen. This hasn’t yet decomposed and causes the high BOD. If you measure the BOD and accumulate the output over a 24 hour period (or 168 hour period if there are days when the machine is lightly used). Mix the output and send the sample to the lab for testing. The average is less than 300 ppm.

If you throw oil into the machine, it may easily exit the mesh immediately and hence get down the drain untreated. However, lumps of fat (for example on meat) will be digested before they can pass through the mesh. Don’t add liquid oil to the LFC – solid pieces of fat are ok.
It’s not the nutrients that increase the BOD – it’s the undigested waste food that does this.

At the bottom of the LFC is a fine mesh that keeps waste food in the machine until it is digested. This then exits as water.

However, as some waste food becomes small, it can go through the machine undigested. So, as much as 3% of the product in the grey water is undigested waste food. For this to be digested as it travels to the sewage plant and in the plant itself, the microorganisms require oxygen, hence the demand.

In the USA, untreated sewage has a BOD of about 200 ppm (mg/l). The output of the LFC is typically about the same as this. The BOD of a pristine river is below 1 mg/l and the sewage plant strives to ensure its discharge is no greater than this. The output of the LFC doesn’t affect the operation of the sewage plant or of what that plant eventually discharges.

In the US, only about 0.06% of the material going to the sewage plant is solid – the rest is water. The LFC doesn’t alter that balance.

In the sewage plant, microorganisms are used to digest the solids. The microorganisms that exit the LFC will continue to digest waste food as it travels to the sewage plant. And this will help clean the drains of the facility.

Over the past 20 years tens of thousands of the LFC machines have been deployed in Korea and Japan – with thousands of machines sold in the USA, Europe, and Latin America.

Numerous studies have been conducted and found no more impact than discharging digested waste from humans.

The LFC installs in the kitchen and requires minimal power and water to operate. It’s convenient to use because waste food can be added at any time. It reduces smelly trash accumulated outside.

Hauling the waste to a remote facility uses resources and is less convenient.




Product quality and service


Yes. Much of the mechanical design and all of the hardware and software is developed in Silicon Valley California. Power Knot’s joint venture company (Power Knot Korea) completes the mechanical design. In this facility in Korea, we have been making LFC machines since 1999. The current model is the fourth generation machine and joins thousands that are already deployed.
The LFC installs in the kitchen and requires minimal power and water to operate. It’s convenient to use because waste food can be added at any time. It reduces smelly trash accumulated outside.

Hauling the waste to a remote facility uses resources and is less convenient.

Three years, bumper to bumper. We believe we’re the only company to be able to offer this and do so because of our great experience building reliable machines.
• Clean daily and check the tension of the chain every six to twelve months. Inspect for leaks every six months.
• Supplement the Liquid Powerzyme (microorganisms) every nine to 18 months.
• Replace the Powerchips every three to five years.
The LFC uses stainless steel throughout. It has stainless steel:
• Chassis
• Outer panels
• Door and handle
• Shaft and arm
• Load cells (to weight the amount of waste food)

Stainless steel is a hard metal suitable for use in commercial and industrial kitchens. Materials such as aluminium or plastic are soft and are difficult to keep clean. This is why Power Knot constructs its LFC only with stainless steel because other metals are unsuitable for business use.

All steel is SAE standard 304 (EN 1.4301) except the load cells. The load cells are 2Cr14Ni.
The LFCs are assembled in Silicon Valley, California, USA of US and foreign components. The major component is the stainless steel chassis, drum, shaft, and arms. These are fabricated in Korea.

Our LFCs use motors from Europe, gearboxes from Taiwan, displays from China, and electronics fabricated in the USA and China. All assembly, testing, and burn in are done in Silicon Valley, California.

It has been mandatory to properly dispose of waste food in Korea for over 15 years. Much technology has evolved to meet the need. Machines have been exported from Korea to Japan to meet the growing need there. The US is now becoming aware of the problems associated with waste food and are capitalizing on all the experience learned in Korea.

Power Knot maintains very high quality with our LFC machines, again building on 15 years of experience in manufacturing the machines. To replicate this in the US would result in a product that is more costly.

We add vital components in the US to tailor the products for the markets we serve.

Power Knot has arrangements with service companies throughout Australia and New Zealand.

They can provide annual maintenance and repairs in the event of a failure. Our international offices and international distributors are responsible for the servicing of the LFCs they sell.

However, the machines are very reliable, are designed for a lifetime of 15 to 25 years, and require only minimal periodic maintenance or service.

Power Knot carries stocks of parts in Silicon Valley, California and can ship for next day delivery. Many of our international offices, international distributors, and service companies carry small parts and can therefore repair an LFC the same day.
