Side-by-Side Spin-On Filter Heads with ∆P Indicator Option

Spin-on filter heads are mounted directly in-line. Filters are easy to replace without special equipment or tooling, reducing downtime. With the use of multiple filter elements, it is possible to lengthen the time periods between element servicing. Multiple-element spin-on filters are designed to filter out even the finest contaminants while creating greater flow capacities and longer service life.


  • Flows Up To: 120 GPM (Return) 50 GPM (Suction)
  • Port Sizes: 1 1/2″ NPTF w/ 2” 4-Bolt Flange; 1 7/8″ – 12 UN (SAE – 24)
  • Pressure: 200 PSI Max.
  • Temperature: Up to +250°F Operating
  • Applications: Petroleum-based fluids; consult factory for synthetic fluids
  • Features: Multiple modular heads bolted together; inlet flow is equally divided among all elements (parallel flow) providing greater flow capacities and longer service life


  • protect pumps, valves or an entire hydraulic circuit from contamination
  • Easy to install and use

ZDF, MF, & MFT parallel flow modular components can be combined into filter head assemblies such as these. Other combinations are available to meet specific filter applications. For technical advice contact your local distributor or the factory. NOTE: Some multiple-head units may require additional mounting support.

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)
