Oil Centrifuge

IOW Group’s centrifuge filters utilize bowl disc technology. Unlike conventional centrifugal spinners/separators, IOW Group centrifuge filtration separators use bowl discs to increase the separation efficiency, dramatically reducing the time that contaminants can stay in the oil. This provides more separation surface area. Bowl disc dramatically speeds up the precipitation of the solids from the liquid.

IOW Group centrifuge filters have dirt/sludge monitoring technology, which informs the operator when the separator needs servicing, saving valuable personnel time on otherwise unnecessary cleaning. The CentriClean remote monitor is Modbus or Bluetooth compatible and can be easily connected to your existing alarm systems.

The Spinner II Products Division was the exclusive North American importer and distributor of oil cleaning centrifuges manufactured by Glacier Metal Company (now Mann Hummel). Eventually, Spinner II became a division of T.F. Hudgins, Inc. In 2016, T.F. Hudgins announced their merger with Allied Reliability, Inc. In 2023, TFH Reliability Group (parent company of Allied Reliability) sold to SOPUS Products.

The Spinner II centrifuge is a bypass centrifuge filtration device. It diverts a small side stream of oil for processing and returns clean oil to the crankcase. Powered only by engine oil pressure (or external pump), the oil centrifuge generates a centrifugal force more than 2,000 times greater than gravity. This force slings contaminants smaller than one micron out of your oil and packs them into a dense cake on the rotor wall. 

An oil centrifuge separates contaminated particles from engine oil to reduce engine wear. An oil centrifuge uses centrifugal force to extract contaminants from the oil stream.

The lubricating oil will gradually be contaminated by small particles originating from the combustion during normal engine operations. We recommend installing a built-on oil centrifuge filter as an additional bypass filter to the built-on full-flow depth filter. The wear rates are reduced, and the engine’s lifetime is extended.

An oil centrifuge filter is operated continuously when the engine is running or at a standstill. The high speed of the bypass oil centrifuge filters is highly efficient for cleaning engine oil, waste motor oil, hydraulic oil, and other industrial fluids.

Nearly all full-flow oil filters are designed to clean the lubricating oil that lubricates the engines’ moving parts. They are designed for a specific flow rate and pressure drop. However, there is a trade-off in performance to get the necessary flow rates and pressure drops required. As engine designs evolve to meet emission requirements, the contaminant loading placed on the engine’s lubricating oil will continue to increase.

Smaller micron particles pass through the filter media continually. These particles build up in the lubricating oil, causing unnecessary wear and damage to the engine, which in turn leads to lower engine performance and increased engine emissions. They also shorten the life of the lubricating oil as the level of contaminants increases.

With today’s emission controls getting tighter and tighter, it is increasingly important to remove these contaminants before they cause any damage to both the engine and the lubricating oil. Poor lube oil quality causes wear on the crankshaft, camshaft, turbocharger, and other essential parts. The centrifuge bypasses only 10% of the dirty oil, but by doing so, it significantly improves the quality of the lubricant, increasing the life and efficiency of the full-flow filter.

With fewer particles moving around the engine, the wear and tear of components are significantly reduced and has the bonus of reducing man hours due to unnecessary servicing.

Supplemental bypass filter typically falls into two (2) categories, centrifugal and absorptive. Centrifugal filters have proven helpful in extending the primary filter life, while absorptive filters reduce acids and contaminants in the oil.

Centrifugal Filters

Engine-mounted centrifugal oil filters remove particles below 1 micron from the oil, such as sludge, wear materials, dirt, soot, and carbonous materials. Centrifugal bypass filters can increase the number of operating hours before the primary filters become restricted.

If engine mount is not an option, you can set up the centrifugal oil filter as a kidney loop system utilizing a gear pump (or triple screw pump).

Centrifugal filtration is the process of using centrifugal force to separate solids from liquids. This method uses gravitational force (g-force) instead of filter media to affect the separation/filtration.

Absorptive Filters

Absorptive filters have absorbent media, such as cotton and cellulose fibers, which absorb acids and moisture and remove contaminants from the oil. Supplemental bypass absorptive filters increase oil capacity and may allow oil and filter change periods to be extended. However, the drain intervals cannot be extended arbitrarily without adequate monitoring systems.
