High level of protection for electronic equipment (E/E) in the avionics bay. Ensuring that the cooling air is CLEAN and DRY, results in:

• Reduced component failures due to contamination
• Improved system reliability
• Reduced maintenance costs

Complete filtration system (housing and barrier filter element) is optimised to provide maximum performance with minimum weight.

With the increased dependence on electronic systems and fly-by-wire technology in modern aircraft, the avionics (electronic equipment) cooling system plays an important role in the overall system reliability.
It is essential that the avionics cooling air (E/E cooling air) is dry and free from contamination.

Filter solutions for avionics cooling

A range of air filtration systems are available:

• Filter assembly (comprising housing, filter element and accessories)
• Cleanable barrier filter elements
• Disposable barrier filter elements
• Inertial particle separators (with or without a barrier filter downstream)

Avionics Filter Assembly, Technical Features

We supply more than just a replacement barrier filter element. Our engineering experts can design a complete filtration system, including the following:

• Optimised performance (pressure drop, filtration efficiency, weight)
• Water coalescing capability (optional)
• Unique design features to separate water droplets from the cooling air
• Integration into the aircraft environmental control system

Avionics Filter Elements, Technical 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
