Racor 75/500MA Duplex Fuel Filter (10 Micron, Heat Shield)

Racor 75/500MA Duplex turbine fuel filter is designed to protect your precious engine components from various contaminants such as dirt, rust, algae, asphaltenes, varnishes and water.

The Duplex multi-function valve allows filters to be used singularly or together, and allows servicing of one filter whilst the engine is running.

The Racor 75/500MA Duplex marine turbine is designed to be fitted on the vacuum side of the fuel transfer pump for maximum efficiency. The Racor turbines work through a three stage process; Separation Coalescing & Filtration explained below.

– Stage One: Separation: As fuel enters into the filter assembly, it moves through the turbine centrifuge and spins off large solids and water droplets which fall to the bottom of the collection bowl.

– Stage Two: Coalescing: Small water droplets bead-up along the sides of the chamber and on the element, once heavy enough these too fall into the bottom of the collection bowl.

– Stage Three: Filtration: Algae, rust and dirt are then filtered from the fuel by the Aquabloc element, as the elements are waterproof they are much more effective and long lasting than water absorbing elements.

The Racor 75500MAX10 duplex filter comes complete fitted with see-through bowls, heat deflection shields and a set of 10 micron elements. The turbine has a maximum flow rate of 454 LPH through a port size of ¾” – 16 UNF.

Replacement Racor turbine elements (2010 series) are available to order with various micron ratings. Racor 2010 turbine elements measure 78mm diameter x 70mm high.
