ENQUIRE NOW I am looking for:


Centrifugal force is extremely useful in the separation and filtration industry. It uses the power and speed of rotation creating centrifugal forces to divide substances of varying densities. These forcesassist to purify oil, wastewater, fuel, and other substances. Here at Interfil, we have studied these processes for more than three decades and built customised solutions.

The reason we stand behind our filtration systems is we drafted, designed, patented, and manufactured them all ourselves, right here in Australia. We have full control of the entire production process, so we can tell you how it works, why it works, and what steps will keep it working. We’re available for servicing, maintenance, and replacement parts. We can also guide you on the best filtration tools for your industry and operation.

Oil and Water

At the moment, we stock five different kinds of centrifuges. Three are in-house models while the last two are Dieselcraft centrifuges we have full faith in. The kind of centrifuge you pick depends on your filtration needs. For example, the two Dieselcraft centrifuges are mostly used to clean oil and are differentiated by size. The OC 20 can clean 3.5 litres per minute, while the OC 50 is twice as powerful, cleaning 7 litres per minute.

They’re used for vegetable oil, engine oil, biofuel, and other oil-based fluids, and they largely extract built up carbon and metal fines.

Interfil centrifuges can be used to clean both used oil centrifuges and wastewater centrifuges. In the latter, it separates water from solid waste, making it easier and cheaper to recycle/dispose of. While Dieselcraft is based on size, Interfil equipment is distinguished by functionality, larger g-forces and overall greater capacity along with options of automatic self-cleaning for continuous operation.

Oil-water separators like Dieselcraft fuel purifiers don’t need to be cleaned as they are primarily used for water and fuel separation. Oil is pumped out of the top and water seeps out of the bottom, leaving the filtration chamber empty. But with centrifuges, bits of dirt and particulate get tossed to the sides of the filtration bowl, where they form a thick layer. This literal pile of dirt will eventually slow the machine and might re-infest your cleaned fluid, so it has to be scraped off periodically. Your selection will, therefore, depend on your work volumes, and how often you can afford to stop.

Filtration and Hygiene

Centrifuges are frequently attached to other machines in your production line. For example, in fruit or potato processing plants, filtration devices are attached at two points. The first collects water from washing raw potatoes/fruits to remove soil and chemicals. The second point cleans water used to rinse the fruits/potatoes after slicing, so the contaminants are mostly vegetable starch/fruit pulp. If the loads are small, you can buy a manual IC-45 M. With this unit, you have to stop centrifuge, detach the bowl, and scrape the sides to remove effluent.

For median processing where, soft pasty solids are present in the bowl, opt for our IC-45-A. It offers semi-auto-clean functionality. Semi-auto being the self-clean only activated on a timer and is only suitable for paste like contaminants in solution. Then, for really busy plants, you can purchase our IC-45-AV that cleans itself automatically without stopping your equipment. This allows you to continue your manufacturing process throughout with no breaks or downtime, and minimal supervision from machine operators. Ideal for any type of solution and solid waste.  Self-cleaning is activated by a change in weight when an accumulation of solids has been collected within the spinning bowl.  The self-cleaning is carried out in seconds and doesn’t interrupt the pump flow to the process.

To look at the selection of centrifuges we have in stock, and find the right one for your needs, call Interfil today on 02 9533 4433.
