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)
