Fit and Forget Engine Protection

The AgustaWestland AW109 helicopter is used in a variety of roles including Emergency Medical Services (EMS), police surveillance, and military operations. These demanding operations can mean anxious and dangerous minutes spent hovering close to the ground, and frequent landings on unprepared surfaces away from their main base.

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 reliable, maintenance-free engine protection system.

The fit and forget PUREair system is an ideal solution for such challenging operations. The system shields the engine inlet from airborne contamination, which results in: Safer operation by protecting against FOD, ice, snow, and sand Increased operational availability Protection against engine erosion. On the AW109S, 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 PUREair 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 71-61-04, available through Pall Aerospace.

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

The Pall PUREair 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.
