Waste vegetable oil (WVO) is waste product from restaurants or kitchens that has been filtered down that diesel engines can run on. The oil must be meticulously filtered and dewatered so as to not cause damage to an engine. Waste Motor Oil (WMO) and Automatic Transmission Fluid (ATF) are used fluids from a vehicle which can be found at mechanic shops. It must be mixed with a slight percentage of gasoline to thin it out and filtered down to 1 micron or less. Both oils are suitable to use as fuel as a diesel alternative.

Should I use WVO or WMO?

In the early 2000s, WVO was the most popular alternative fuel. Since then though, WMO has become the dominating alternative fuel today in the United States. Reasons for WMO becoming more popular: It has become easier to source, has fewer contaminants than WVO, and heated fuel lines are not required.

What is a centrifuge?

A centrifuge is a device used to separate suspended particles from a liquid or gas by spinning it at high speeds in a container. This process, known as centrifugation, uses the force of gravity to separate the particles according to their size and density.

Centrifugation is commonly used in oil filtration, where different particles are separated from the oil to obtain pure oil for use in industrial applications.

What are the Benefits of Centrifuge Oil Filtration?

Oil filters are the most common way to clean oil before using it as a fuel, there is an issue though with filters! Manufacturers typically report filter efficiency as the percentage of contaminants 20 microns and larger removed from oil. Filters using traditional media are often only 40% to 80% efficient at 20 microns. This means that thousands of particles are passing through the filters which will lead to clogged injectors and other mechanical issues. Using a centrifuge will decrease the likelihood of this happening!

Centrifuges have a higher efficiency than oil filters can provide and will reduce the cost of filtration. No more buying messy filters. Set it up, open your oil valve and the centrifuge will clean it down to 1 micron capturing containiments.

What are the Types of Centrifuges?

At PA Biodiesel Supply, we offer two styles of waste oil centrifuges depending on your needs and purpose.

The Ultimate Force Centrifuge is a direct drive centrifuge inflicting 1,600 of G-force on oil, cleaning it down to 1 micron. Featuring an easy-to-clean enclosed bowl, it will capture all the debris and sludge in your oil ensuring only clean oil escapes. The Ultimate Force Centrifuge is our top-of-the-line product and best seller!

The pressure centrifuges are designed for removing grit, dirt, and debris to 2 microns or less. These are multiple-pass centrifuges requiring 20/30 passes depending on the amount of contaminants present in the oil. The oil is recirculated in a one-barrel system cycling the oil multiple times until it is clean. The pressure centrifuge is great for beginners or those with limited space. It will not pull out water and sludge because it operates at high pressure, this centrifuge purely removes debris. Pressure centrifuges are a great and cheap investment to start cleaning oil at home or for industrial use!

What is the G-force of a centrifuge?

Our Ultimate Force Centrifuge inflicts 1,600 G-Force, and our pressure centrifuges inflict between 1200 to 2,000 G-force depending on the model and rpm of the unit. 

Will a centrifuge remove water?

At PA Biodiesel Supply our centrifuges will not capture water. Many competitors will claim that their centrifuge will capture and separate water from oil, but this is simply not true. Our bowl for the Ultimate Force Centrifuge has a volume of 0.5 gallons, one of the largest on the market! If you have more than 0.5 gallons of water in your oil, it will pass through the unit uncaptured. An important note, water can be removed using heat! We highly recommend using an inline heater or band heater when cleaning your oil to increase efficiency and decrease the water content in your oil.

Does a centrifuge remove sludge?

Yes! A centrifuge will capture sludge and emulsified oil.

How much money will I save?

You can save thousands of dollars! Ultimately only you know how much diesel you use annually. If you purchase our Ultimate Force Centrifuge, at this time with diesel at almost $4 per gallon,  you will only need to consume 400 gallons of oil to start saving money! 

The average American commutes 14,263 miles per year. If averaging 16 mpg this equates to 891 gallons of fuel purchased in a year. After purchasing our Ultimate Force Centrifuge you can still save almost $2,000 in year 1 by producing your own fuel! One of our customers owns a heavy machinery construction business and purchased several Ultimate Force Centrifuges. Over 6 years he has produced more than 60,000 gallons of fuel saving hundreds of thousands of dollars!
