Designed to purify oil while operational, they retain a lot of used oil after replacement. As per Waste Prohibition 5(1)(j) of GRN 636 (National Norms and Standards for the Disposal of Waste to Landfill) oil filters may not be disposed of at landfill's. We collect and process oil filters as per global best practises to ensure recycling in an environmentally safe manner. Please contact us for more information on this value added service.
The outside of the filter is a metal can with a sealing gasket that allows it to be tightly held against the engine’s mating surface. The base plate of the can holds the gasket and is perforated with holes around the area just inside the gasket. A central hole is threaded to mate with the oil filter assembly on the engine block. Inside the can is the filter material, most frequently made from synthetic fiber. The engine’s oil pump moves the oil directly to the filter, where it enters from the holes in the perimeter of the base plate. The dirty oil is passed (pushed under pressure) through the filter media and back through the central hole, where it re-enters the engine.
