Fit and Forget Engine Protection

The “fit and forget” PUREair system for the Eurocopter AS330/332 and Denel Oryx series of helicopters is an ideal solution for challenging environments. The system shields the engine inlet from airborne contamination, which results in:

• Safer operation by protecting against sand and dust, foreign object damage (FOD), ice, and snow
• Increased operational availability
• Protection against engine erosion
• Increased time between overhauls

Many of the Puma, Super Puma, and Cougar fleets currently in service around the world are fitted with the PUREair system.

The latest design of the AS332 EAPS consists of two modules with forward facing, pneumatically operated bypass doors. Part numbers: AS330 QB0116/117/118/119/120/121 (6 separate panels) QB2801 QB0267 (UK RAF) AS332, EC225, EC725, Oryx QB0342   QB10412-01 (scavenge fan)

For the Super Puma helicopter, icing trials were conducted by Eurocopter, and Pall’s PUREair system is certified for cold weather flight capability.

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, available through Pall Aerospace.

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

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.
