Avionics (E/E) Cooling Filters

With the increased dependence on electronic systems and fly-by-wire technology in modern commercial aircraft, the avionics (electronic equipment) cooling system plays an important role in the overall system reliability.

It is essential that the avionics (E/E) cooling air is dry and free from contamination.

Features

  • Fine filtration efficiency (significantly better than the ARINC international standard of 400-micron absolute)
  • Removal of oil mist and fine particulate contamination, such as carbon
  • Hydrophobic filter elements - not affected by moisture
  • Low differential pressure
  • Long filter element service life

Benefits

  • Increased E/E system reliability, reduced component failures due to contamination
  • Protection of the critical components within the avionics cooling bay

How Does it Work?

There are two types of air filter system that can be used:

(A) High-efficiency, barrier filter elements.
(B) Inertial particle separators (with or without a barrier filter downstream)

Filter assembly containing an inertial separator housing and barrier filter.

Applications

Pall has extensive experience in providing avionics filtration systems on commercial and military programs, including the A300/310, A320, B737, B747, B757, B767, B777 aircraft, as well as the AH-64, CH-53K, Rooivalk and V-22 helicopters.

We have been working together with Airbus on the A320 avionics cooling filtration system since the early 1990’s and have an in-depth understanding of how to prevent sand, dust and water accumulation in the avionics bay.
