Where are filters used within the Aerospace and Defence industry?

Filters protect vital sub-systems in aircraft, helicopters, military vehicles, missiles and spacecraft such as:

• Primary and secondary flight controls
  Filtering hydraulic fluids used to operate mechanisms that control the direction of an aircraft during flight, landing and take-off conditions.

• Fuel management
  Used within fuel control and fuel pump metering, as well as a range of fuel system hierarchal filtration components.

• Fuel tank inerting
  Providing filtration for engine bleed air, removing fluidic and particulate contamination to a sub-micronic level.

• Power generation
  Used in auxiliary power and ground power units plus generators and starter generators.

• Air intakes
  For filtering large volumes of particulate in highly contaminated environments.

• Environment control
  Air supply, thermal control and cabin pressurisation.

• Potable water systems
  Used on aircraft for passengers and crew, as well as transport from source.

• Avionics and supplementary cooling
  Removing particulate from coolant systems such as power electrons, cargo bay air conditioning and galley coolant systems.
