Centrisep® Engine Advanced Protection System (EAPS) for Eurocopter SA315 and SA316 Series Helicopters

Fit and Forget Engine Protection
Eurocopter’s Lama and Alouette helicopters are used in a variety of commercial and military roles, including passenger and troop transport, agricultural activities, and mountain rescue. These helicopters must be ready 24/7 for rapid deployment to any location. They require a maintenance-free engine protection system.

The “fit and forget” Centrisep Engine Advanced Protection System (EAPS) is the ideal solution for such challenging operations. It 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

On the Lama and Alouette helicopters, the unit consists of two flat panels mounted on intake pavilions, fitted on either sides of the engine intake. The EAPS unit is supplied as a complete, stand-alone kit.

Part numbers:

• QB0285¹ (Lama, Cheetah)
• QB0299¹ (Alouette, Chetak)
  ¹ Retrofit kits are available for operators with older Centrisep EAPS. 

                          
Scavenge system:

• Ejector

Certification:

• Eurocopter data sheet 2005-01, Issue 02, June 6, 2006

The Centrisep EAPS is certified for operation in case of inadvertent entry into icing conditions, and therefore is allowed to operate without the need for a by-pass door and differential pressure monitoring systems.

Maintenance

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

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

The Pall Centrisep EAPS 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.

The Lama and Alouette helicopters are fitted with Pall's Centrisep EAPS, a “fit and forget” solution that provides enhanced protection against engine erosion.
