500 MAM Series Marine Turbine Diesel Fuel Filter

Every engine would run better with a system that cleans fuel, removes water, heats fuel and senses when it's time for service.
A system that makes the money you spend on diesel fuel work harder for you, instead of working against you.
That system is the Racor Turbine Series and it's the most complete, most efficient, most reliable engine protection you can install.
The legendary Turbine Series is a fixture whenever engines demand the confidence of heavy duty, high capacity water separation and fuel filtration.

Turbine Series filters protect precision engine components from dirt, rust, algae, asphaltines, varnishes, and especially water, which is prevalent in engine fuels. They remove contaminants from fuel using the following legendary three stage process:

Stage 1 - Separation
As fuel enters the assembly, it moves through the centrifuge and spins off large solids and water droplets, which are heavier than fuel, and fall to the bottom of the collection bowl.

Stage 2 - Coalescing
Small water droplets bead-up on the surface of the conical baffle and cartridge filter. When heavy enough, they too fall to the bottom of the collection bowl.

Stage 3 - Filtration
Proprietary Aquabloc® II cartridge filters repel water and remove contaminants from fuel down to 2 micron (nominal). Aquabloc II cartridge filters are waterproof and maintain their effectiveness longer than water absorbing filters.

Optional in-filter heaters are a cold weather starting aid available for Racor turbine filters. The heater has an internal, non-adjustable automatic thermostat that turns heater ON when fuel temperature drops below 50°F (10°C) and turns OFF when fuel reaches 80°F (27°C). Heat is supplied in the filter assembly just below replacement filter to melt wax crystals and allow fuel to pass through the filter for quick, easy starting.
