SRF Series
Modular Multi-Element Hydraulic Return Filter: High Dirt-Holding Capacity
The SRF Series modular tank mounted return filters feature high dirt-holding capacity and customizable single, dual, or triple element configurations. Designed for hydraulic systems that demand longer service intervals and maximum filtration performance, these filters deliver up to 83 GPM flow. The SRF Series offers industry-standard mounting for easy retrofits, making it the ideal solution for tough applications with high contamination loads.

Zinga Filter Media Types
Z-Glass Media
Multi-Layered, non-woven glass media that provides the highest levels of depth filtration efficiency and capacity. Higher capacity means longer service life. Coupled with a steel support mesh, Z-Glass can withstand higher differential pressures.
Cellulose Media
Traditional paper based media that provides a nominal level of depth filtration and capacity. Used with petroleum-based fluids only. Some grades of cellulose include a layered glass fiber substrate to provide more efficiency.
AquaZorb Media
Water absorbing cellulose based media designed specifically to absorb and retain free water from petroleum-based fluids. Commonly used in offline systems, AquaZorb will operate until it is fully saturated and ultimately curtail flow through the media. A system by-pass valve and service gauge is recommended when using AquaZorb.
Stainless Steel Mesh
Woven in a variety of precision patterns, stainless steel mesh provides a basic surface type filtration with very low differential pressure. Applications include pump protection and “last chance” valve protection. Stainless steel mesh can be serviced by ultrasonic cleaning. (30: 560µ, 60: 280µ, 100: 141µ, 200:75µ, 200×1400: 10µ)
