Centrisep® Engine Advanced Protection System (EAPS) for AgustaWestland AW139 Helicopters

Fit and Forget Engine Protection

The AgustaWestland AW139 helicopter is used in a variety of roles, including executive transport, search and rescue, and Emergency Medical Services (EMS).  These demanding rescue operations can mean anxious and dangerous minutes spent hovering close to the sea or ground, and frequent landings on unprepared surfaces.

Helicopters used in these capacities must be available 24/7 for rapid deployment to any location.  Their critical missions cannot be delayed or restricted by operational challenges like a blocked filter; they require a maintenance-free engine protection system.

The “fit and forget” Centrisep EAPS is an ideal solution for such challenging operations.  It shields the engine inlet from airborne contamination, resulting in: Safer operation by protecting against FOD, ice, snow, and sand Increased operational availability Protection against engine erosion On the AW139, there are two curved panels which are aerodynamically shaped to match the profile of the engine cowlings (port and starboard). They replace the standard screen over the side-facing air intakes.

Maintenance

There are no inlet barrier filters to replace or clean;  the Centrisep EAPS is a “fit and forget” system. As with all aircraft equipment, routine visual inspection is recommended.
In case of damage, please refer to the Component Maintenance Manual 75-60-00, available through Pall Aerospace.

The Pall Centrisep EAPS solution is also an environmentally friendly alternative to oil-wetted barrier filters. There is no filter replacement and no daily cleaning as with oil-based solutions, which are difficult and expensive to dispose of.

For additional information about this product, please contact your local Pall representative.

The AW139 helicopter is fitted with Pall's Centrisep EAPS, a “fit and forget” solution that extends the erosion life of the engine.
