These filters are just some of the industry standard products available. We also specialize in the design and manufacture of exclusive filter designs for the aerospace industry.

Fuel Filters
Fuel filter assemblies are designed to meet your application's most stringent performance requirements. Each filter is designed with the utmost attention paid to performance and reliability. Products include engine or airframe mounted, main or last chance fuel filters. Design characteristics include:

  • High Performance Filter Elements (disposable or cleanable)
  • Absolute Filtration Ratings
  • Last Chance Filtration
  • Bypass Valves
  •  Microdelta® Impending Differential Bypass Indicators or Electrical Switches
  • Light-Weight Aluminum Housings
  • Various Mounting Configurations
  • Drain--Anti-drain Valves or Ports

Lubrication Oil Filters
Lubrication oil filters are designed to provide the extra-fine filtration and dirt holding capacity required to increase the operating life and reduce operating costs of aircraft transmissions and engines. By removing the contaminants found in these systems, transmission parts and engine bearings will operate more efficiently which equates to safer and extended operating times at reduced cost. Purolator Facet lubrication oil filters provide:

  • Extra-Fine Filtration
  • High Dirt Holding Capacity
  • Cleaner Components After Hours of Operation
  • Reduction of Sludge in Oil
  • Reduction in Wear Metals and Secondary Damage
  • Extended Oil Change Intervals
  • Increased Component Life

Hydraulic Oil Filters
Hydraulic oil filters are designed to provide an extra-fine degree of filtration in today's ever increasingly complex hydraulic system. These filters protect all of the components used in these systems from foreign-born contaminants and contaminants generated by normal system operation. Removing these contaminants is crucial to protect the fine clearances found in hydraulic system components. This permits these systems to operate more efficiently and for extended periods of time. Characteristics include:

  • Qualified filter assemblies: MIL-F-8815, MS 28720 and AN 6234
  • High Filtration Efficiency, Beta Ratio
  • High Pressure Filter Housings
  • Various Materials and Mounting Configurations Available
  • High Collapse Pressure Filter Elements
  • Suitable for All Types of Hydraulic Fluids
  • Epoxy or Welded Element Designs
  • Bypass Valves
  • Microdelta® Differential Pressure Indicators
