Centrisep® Engine Advanced Protection System (EAPS) for Eurocopter EC135/EC635 Helicopters

Fit and Forget Engine Protection

The Eurocopter EC135 is the helicopter of choice for police and Emergency Medical Services (EMS).  Their demanding missions mean frequent landings on unprepared grounds - sometimes as many as twenty times a day.  Under such conditions, engines can suffer from early erosion damage.

EMS helicopters must be ready 24/7 for rapid dispatch to any location. Their 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 Engine Advanced Protection System is an ideal solution for such challenging operations. It shields the engine inlet from airborne contamination which results in: Safer operation by protecting against FOD, ice, snow, and rain Reduced pilot workload (no bypass door activation due to filter blockage) Increased operational availability Protection against engine erosion.

On the EC135, the Centrisep EAPS consists of a curved panel which is integrated into the helicopter design by the OEM.  Pall has developed a complete kit, comprising the modules and the rotor mast seal.

Part numbers:

• QB0594-01, QB0664-01 (Black)
• QB0594-02, QB0664-02 (Silver)

Note:  QB0594-01/02 includes the Centrisep EAPS plus the rotor mast seal. QB0664-01/-02 is for the Centrisep EAPS panel only.

Scavenge system:

• Fan

Certification:

• Eurocopter SB: EC135-71-028

Certified for operation in the event of inadvertent entry into icing conditions, the EC135 is capable of operating without 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 aircraft equipment, routine visual inspection is recommended.

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 that are difficult and costly to dispose of.

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

The EC135 helicopter is fitted with Pall's Centrisep EAPS, a “fit-and-forget” solution that extends the erosion life of the engine.
