Centrisep EAPS Operation

Contaminated air enters the Centrisep EAPS and is given a swirling motion by the vortex tubes.
Particles and water droplets are thrown radially outwards, by centrifugal force, to the walls of the vortex generators.
The contaminants are then scavenged overboard with a small portion of the inlet air, while clean air flows through the centre of the vortex generator tubes into the engine. Since there is no filter blockage, the Centrisep EAPS has a constant pressure drop. Therefore the impact on engine power remains constant.

Scavenge Systems (using Ejectors or Fans)

Contamination is removed from the Centrisep EAPS by an additional scavenge airflow. This scavenge airflow is induced by either ejectors or fans. For the Centrisep EAPS to operate efficiently, the scavenge system must be on. We recommend activating the scavenge system at take off.
