Filter Assembly 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.
