描述
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.

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.
