Pall PUREair System for Eurocopter SA341 and SA342 Series Helicopters

Improved Engine Protection

A certified upgrade is now available to replace the 30-year-old PUREair design. The new and improved unit provides a dramatic increase in dust separation efficiency and hence significantly increases the MTBUR for engine erosion.

The performance enhancements were achieved without any negative effect in terms of weight or power penalty compared to the previous equipment.  In-service experience has demonstrated the superior performance of the PUREair system over other filtration devices that demand regular maintenance and cleaning.

Pall’s “fit and forget” PUREair system is an ideal solution for challenging environments. The system shields engine inlets 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 Gazelle helicopter, the unit consists of two halves fitted to the Astazou annular engine air intake.

SA342 Gazelle Centrisep® Engine Advanced Protection System (EAPS)

Part Numbers:

  • QB0491

Scavenge System:

  • Ejector

Certification:

  • Eurocopter approved
Certified for operation in case of inadvertent entry into icing conditions, enabling it to operate without the need for a by-pass door and differential pressure monitoring system.

Maintenance

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

    The Pall PUREair solution is 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.
