HF Series

Spin-On Filter Heads with ∆P Indicator Option

Zinga Spin-on filters are used to protect pumps, valves or an entire hydraulic circuit from contamination. Spin-on filters can be found in mowers, tow trucks, truck-mounted aerial lifts and cranes, pavers, compactors, wood splitters and chippers, trenchers and utility terrain vehicles (UTVs).

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)
