Filter Assemblies for Aerospace

Optimized designs using our knowledge of Fuel, Lube and Hydraulic, and Liquid Coolant filtration systems

  • Compact packaging and low weight
  • High Reliability
  • Qualified using in-house test facilities
  • OEM approved


Maintaining a specified level of fluid cleanliness is critical to the operation and reliability of aerospace fluid systems and equipment.

A filter assembly consists of a filter housing and a high-performance filter element. Where specified, it can include bypass valves, non-return valves, differential pressure monitoring devices, and other sampling points.

Features

  • Incorporates high performance filter elements using Pall proprietary media
  • High-strength construction
  • Filter Bowl & Filter Head meet fatigue and pressure requirements (dependant on application)
  • Low differential pressure
  • Bowl-locking mechanism to prevent filter bowl loosening under vibration in service
  • Electro-Static Discharge (ESD) pin

Benefits

  • Light-weight designs
  • Small space envelope
  • Improved system performance and reliability
  • Qualified to stringent OEM requirements

Aerospace filter assembly cross-section


The system fluid enters the assembly through the inlet port. It flows through the inlet and into the filter element.

  • Filter Element
    Particulate contamination including metals, dust, fibers, seal material, etc., is removed and captured by the filter element. The clean fluid then exits the assembly through the outlet port.
  • Electro-Static Discharge (ESD) pin
    Some fuel filter elements include Pall’s patented ESD pin. This feature dissipates any charge build-up and prevents component damage due to electrostatic discharge.

  • Monitoring Devices/Sensors
    After a period of service, the element will become loaded with contamination and require replacement. The Differential Pressure Indicator/Switch (DPI/DPS) located in the head of the filter assembly indicates when the filter element is becoming plugged with contamination and needs to be changed.
    A thermal lockout device (optional) prevents false indication at cold start conditions.
  • Bypass Valve
    If the element is not changed, the filter element differential pressure will continue to rise. Above a certain value, the bypass valve opens and the fluid by-passes the filter element and passes directly to the outlet port.
  • Shut-Off Diaphragm (optional)
    This prevents loss of fluid during element change-out.
