The Racor 700 Series Fuel Filter Water Separator is a two-stage filtration and re-priming system that’s designed for use in heavy-duty diesel applications. The assembly comes equipped with a state-of-the-art integrated fuel pump, which allows for easy priming and simplified service by eliminating messy filter pre-filling and engine hard starting.
To meet the unique requirements of customer’s engines, the 700 Series is available in a wide range of configurations. The system can be fitted with either a 12-volt DC brushed motor “roller-cell” pump or a 12/24-volt DC brushless motor generator-motor (gerotor) pump. Both fuel pumps offer electric on-demand priming at the push of a button and have output pressures regulated to 15 psi (103 kPa).
All 700 Series configurations utilize Racor’s proprietary Aquabloc® filtration elements. Aquabloc® is a unique engineered media that incorporates pleat-spacing corrugations and a graduated pore structure to increase dirt-holding capacity and extend filter life. The media is waterproof and rustproof, capturing contaminants while the specially treated surface separates and coalesces water from the fuel; causing the water to gather into large droplets that then fall into the clear collection bowl.
Aquabloc® elements are available in two different ratings:
30 micron (98%@30 micron) – Ideally suited as a pre-filter to protect downstream filters from excessive contamination. Extends the life of on engine filters.
10 micron (98%@10 micron) - Captures more contaminants than 30 micron elements, and more effective at stopping water. Extends the life of the entire fuel system.
