Racor Filtration

Racor is the global leader in fuel, air, oil, and coolant filtration systems for internal combustion engines and fuel delivery. Founded in 1969, the company’s product line includes fuel filter/water separator systems, high flow filter vessels and elements, oil filter systems, automatic transmission filters, heavy-duty engine air filters, crankcase ventilation filter systems, and coolant products. Racor also offers concentrated additives for fuel, gasoline, and lube oil. Applications include engine-powered equipment in the on-highway, off-highway, marine, agriculture, and stationary power markets.

Heavy-Duty Standard Air Filters for On-Highway, Off-Highway, and Stationary Applications
Racor AFSF Standard Air Filters are designed to be connected to the air intake of the gasoline or diesel engine.
How They WorkAir flows through static vanes (plastic or metal) which causes the air to spin. Centrifugal force separates the heaviest impurities (dust, dirt, insects, and other debris) from the air stream. These contaminants are discharged automatically through an integral evacuator valve. Only purified air flows to the air filter elements (primary and safety stages of filtration).
Typical Applications• Agricultural Machinery• Earth-Moving Equipment• Stationary Engines/Generator Sets• Trucks, Buses, and Recreational Vehicles• Material Handling Equipment• Snow Removal Equipment and Street Sweepers

These assemblies are designed and tested for today’s new alternative fuels: Compressed Natural Gas (CNG), Liquid Natural Gas (LNG) and Liquid Propane Gas (LPG). CNG, LNG and LPG have the same problems that plague diesel and gasoline, particulate contamination collects during handling, water condenses in tanks, and compressors leak oil into the fuel stream.

The precision components necessary for the efficient operation of an alternative fuel system demand superior filtration. Racor anticipated the need for ultra-fine filtration at the pressures required by compressed natural gas. The answer is the industry’s first, most complete and most
efficient line of alternative fuel filters/coalescers.

FFC series filters are designed to protect critical engine components in CNG, LNG, and LPG powered vehicles. Contaminants can be introduced into a vehicle’s fuel tank when being fueled or may come from compressors and/or storage facilities. A grade 6 coalescing filter is specifically designed to remove oil, water, and solid contamination from compressed natural gas.
The patented coalescing filter removes 99.97% of all aerosols in the 0.3 to 0.6 micron range.

These fuel filter/coalescer elements are produced by a patented process of arranging micro-glass fibers into a tubular form. During operation, fuel is forced through the coalescing media from the inside of a cartridge through a tubular wall to the outside, where large droplets fall to the bottom of the housing. Oily water emulsion accumulates until drained while dirt particles remain trapped and collect on surfaces of fibers.
