Dieselcraft is the leader with over 50 years experience in the design and manufacture of industrial centrifuges.
Our centrifuges are used in a variety of settings across various industries including industrial, commercial vehicles, agricultural and marine. They all cut the cost of oil changes by 30% or more.
ALL solid particles above 1 micron are permanently removed from your oil
Let us help you calculate the real return on investment of cleaner engine oil.
If an oil change costs $300 and your truck requires four oil changes per year, your annual maintenance cost is approximately $1,200 based on driving 100 miles per day and changing oil every 6,000–7,000 miles.
Now consider extending oil life by just 33%, increasing your oil change interval to approximately 9,000 miles. Instead of four oil changes annually, you reduce that number to about 2.6 oil changes per year. Your annual oil maintenance cost drops to approximately $792.
That is a savings of over $400 per truck every year.
You also reduce:
- Waste oil disposal
- Oil filter replacement costs
- Downtime for service
- Labor and maintenance expenses
Contact Dieselcraft today and let us show you documented proof that you can safely extend oil life and reduce operating costs. The sooner you start, the sooner you begin saving money.
Why Standard Oil Filters Are Not Enough
Most engine wear particles are too small for conventional full-flow oil filters to capture effectively.
According to the SAE, particles as small as 4 microns can cause up to 77% of engine wear.
Most modern engines use full-flow oil filters rated at approximately 25 microns. Even then, a typical 25-micron filter is only about 80% efficient, meaning many smaller abrasive particles continue circulating through the engine.
Those particles contribute directly to:
- Bearing wear
- Injector wear
- Turbocharger damage
- Reduced engine life
- Increased maintenance costs
How the Dieselcraft Centrifuge Works
The Dieselcraft Centrifuge cleans engine oil using centrifugal force that is up to 2,000 times greater than gravity.
Instead of trapping contaminants like conventional filters, the centrifuge physically separates soot, dirt, wear metals, and fine particles from the oil stream. The contaminants are removed from circulation entirely rather than remaining suspended in the oil.
Unlike standard filters that eventually plug and restrict flow, the Dieselcraft Centrifuge maintains continuous cleaning performance while reducing particle contamination levels throughout the entire oil system.
Benefits include:
- Cleaner engine oil
- Reduced engine wear
- Longer oil life
- Lower maintenance costs
- Reduced filter usage
- Extended engine service life
In many engine applications, oil drain intervals using conventional oil can be safely extended by 30% to 50% when proper oil analysis procedures are followed.
Stop throwing away usable oil. Let Dieselcraft help you protect your equipment and reduce operating costs.

Paper Filters
You have an engine in a vehicle or a vessel or generator in an application that is worth $20,000 or maybe $200,000 and you are protecting it with a $8 paper filter?
During this 12,500-mile interval, more than half a pound (8.5oz) of soot could enter the oil.
Cleaning the Dieselcraft Centrifuge
CAUTION: Hot oil can be dangerous and may burn the skin. Wear proper protective clothing when working with hot engine parts and hot oils. Avoid unnecessary skin contact with oil.
The Dieselcraft Centrifuge is very simple. It does not require any expendable parts or filters.
At every service period, you just have to open the centrifuge rotor, remove all dirt collected in the rotor then re fit the rotor and centrifuge cover.
- Unscrew top nut and remove the centrifuge cover.
- Lift the rotor completely off the shaft quickly and allow it to drain into an appropriate container.
- Prepare to unscrew rotor nut. Place the rotor, nozzles down over a 1-2” wide wooden block. You will see the block will stop the rotor from turning. Unscrew the rotor nut. The rotor nut should not be opened by hand.Unscrew it with a small adjustable wrench. Never grip the rotor nut tightly in clamping device like a bench vice. It may damage the rotor body permanently.
- Remove rotor cover by use of a RUBBER MALLET. Hold the rotor in one hand by gripping the cover so the rotor nut shaft is UP and tap the shaft lightly. This will cause the two part to separate. DO NOT USE A HARD FACED HAMMER. The top bushing can be damaged if hammered on.
- Remove the deflector that is under the cover.
- Remove the dirt collected from inside the rotor cover by the use of a plastic or dull metal scraper. Clean all the rotor parts thoroughly.
The dirt removed from engine oil is considered Hazardous Material. Dispose of it in the proper manner based your the laws of your county or state.
Re-Assembly
Always ensure that the arrow marks on rotor cover and rotor are matched after assembling the rotor. The rotor body is dynamically balanced. Mismatch of arrow marks on rotor cover and rotor will result in excessive vibration.
Do not over tighten the top nut. Snug plus 1/2 turn is all that is needed. Over tightening top nut will damage the centrifuge permanently.
Do not drop, hammer upon, distort or force during disassembly or reassembly. You may damage the device and void the warranty.
Frequently Asked Questions
Centrifugal oil cleaners use engine oil pressure to spin a rotor at high speed (often thousands of rpm). The centrifugal force generated is thousands of times greater than gravity, forcing solid contaminants to the inside walls of the rotor where they are collected and later removed manually.
A standard paper or full-flow oil filter traps contaminants but eventually plugs and reduces oil flow over time. A centrifuge actively separates contaminants from the oil stream and holds them independently, maintaining a more consistent cleaning performance and allowing for extended oil life.
Dieselcraft’s oil centrifuge units remove particles down to about 1 micron or smaller, far beyond the typical capability of conventional full-flow oil filters that trap particles around 25 microns.
The system does not begin operating until engine oil pressure reaches 28 PSI. This ensures the engine has established proper lubrication before the centrifuge engages.
At 28 PSI, the rotor spins at approximately 3,000 RPM, generating about 375 g’s of centrifugal force.
At 40 PSI, rotor speed increases to roughly 4,700 RPM, producing over 900 g’s of cleaning force.
NO 3/4 will not work. The system will operate correctly as long as the vertical drop on the return line is 12 inches or more and the return line is 1 inch ID. If the drop is less than 12 inches, the return line must be increased to 1 1/4 inch in diameter.
Any back pressure in the return line will cause the centrifuge to stall and stop functioning. The return port must discharge into an open, unrestricted space with zero back pressure.
The oil pressure drives the centrifuge rotor and when the oil leaved the rotor the pressure is Zero. So the air pump is used to add pressure inside the centrifuge to create pressure to return the oil to the engine. The centrifuge can be below the return point by 3 feet if needed.
The pump is very quiet compared to the engine noise. The pump MUST be kept dry so under the dash is fine
Look above the filter housing there is a pipe plug that is used for the oil supply or find the oil pressure sending unit and “T” into it. The kit comes with hoses and fittings to compete most jobs.
