Element Assemblies

Element AssembliesPurolator Facet filter element assemblies have been used by the aerospace industry for over 50 years. Our experience in the design, testing and manufacturing of these products is proven daily with their use aboard most aerospace applications.

Purolator Facet offers a range of products qualified to Mil-F-5504. Download a list of these assemblies and elements. (PDF; 15.6 KB)

Impregnated Composite Fiber Pleated Filters.
Microfil filter elements consist of a multiple-layer composite of organic and inorganic materials. Each layer is selected to perform a specific function (ie., high dirt-holding retention, fine filtration and upstream layer support). Microfil filter elements are designed to provide optimal filtration performance in ranges of 1 to 100 micrometres absolute even under extreme operating conditions.

Operating in temperature ranges of -65 degrees F to +375 degrees F and at operating pressures of up to 4500 psid, Microfil filter elements are compatible with most fuel, lubrication oils and hydraulic fluids used in today's complex aerospace systems. Microfil elements offer:

  • High Filtration Efficiency, Beta Ratio
  • Absolute Filtration Ratings
  • Suitability for All Types of Operating Fluids
  • High Pressure Applications
  • Excellent Dirt Holding Capacity
  • High Temperature Applications
  • Disposability

Impregnated Cellulose Pleated Filters.
Micropleat filter elements offer a cost effective means for the utilization of a non-cleanable filter element in most hydraulic and fuel applications. Micropleat elements are designed to provide optimum dirt holding capacity and particulate removal in the 3, 5, 10, 20 and 40 micrometer range. Micropleat is suitable for operation in temperatures of -65 degrees F to +275 degrees F. Elements can be designed to withstand up to 500 psid with high flow fatigue cycles without deformation.

Purolator Facet has a full line of Micropleat filter elements qualified to meet the requirements of MIL-F-5504 and in industry standard sizes of AN6235 and AN6236 series. Micropleat filter elements offer:

  • Low Cost, Disposable Filter Element Designs
  • Suitablity for Most Fluid Applications
  • Numerous Filtration Ratings Available
  • Proven Filtration History
