R25S Spin-On Filter Elements - Diesel, 2 Micron

Spin-on Series Replacement Cartridge Filter Elements are compatible with Racor’s line of Spin-on Series fuel filter / water separator assemblies. The elements exhibit exceptional removal efficiency of both bulk and emulsified water, low restriction of fuel flow, and high dirt-holding capacity. Their unique design makes them capable of performing in modern diesel engine applications, where high-pressure conditions can cause tiny particles of dirt and water to score and erode precision components, leading to engine damage and increased downtime.

The filter body is protected with a durable electrostatically-applied powder coating for superior corrosion resistance. The spin-on filter design is simple to service and features a reusable clear engineering plastic or metal contaminant collection bowl with a self-venting drain for draining out collected contaminants and water.

All Spin-on Series replacement cartridge filter elements utilize Racor’s high-efficiency Aquabloc® engineered media. Aquabloc® is a blend of high-grade cellulose compounded with resins and a special chemical treatment. It 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, which causes the water to gather into large droplets that then fall into the fuel filter’s collection bowl.

Aquabloc® elements repel water and remove solid contaminants from fuel at 98% efficiency of their micron rating. To meet the unique requirements of customers’ engines, three different micron ratings are available for purchase, including:
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 is more effective at stopping water. Extends the life of the entire fuel system.
“2” micron (98%@4 microns) – Provides maximum water removal and filtration and is capable of protecting all modern injection systems, while greatly extending the life of difficult-to-service on-engine filters.
