Pall PUREair System for MIL Mi-8 Series Helicopters

Fit and Forget Engine Protection

The Mi-8 helicopter is a multipurpose helicopter used in a variety of roles, including passenger and military troop transport, fire-fighting, and search and rescue.  These demanding missions can mean anxious and dangerous minutes spent hovering close to the sea or ground, and frequent landings on unprepared landing zones.  In addition, these helicopters must be available 24/7 for rapid deployment to any location.

The “fit and forget” PUREair system is an ideal solution for such challenging operations. It shields the engine inlet from airborne contamination which results in:
  • Safer operation (protection against sand and dust, FOD, salt spray, ice and snow)
  • Increased operational availability
  • Enhanced protection against engine erosion
  • Reduced maintenance and operational costs
    
On the Mi-8 helicopter, the unit consists of a box-shaped filter installed in front of the engine air intakes.

     

Part numbers:

  • QB0371

Scavenge system:

  • Fan

Certification:

  • Russian Helicopters, JSC
In June 2009, Pall signed an agreement with Russian Helicopters for the Mi8/17 modernization program.  Part of this agreement incudes the certification of the Pall PUREair equipment.  A Service Bulletin authorizing installation of the PUREair system on the civil helicopters is anticipated following completion of type certification flight trials.  
There are no additional limitations for operations in winter conditions. It is allowed to operate without a by-pass door and differential pressure monitoring systems.

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. 

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.

Additional Information

Pall Aerospace has provided engine inlet protection for Russian helicopters since 1980. The original MIL PUREair design evolved from the PUREair system that Pall designed for the Commando helicopter, an Army Aviation version of the Navy Sea King. At the request of North African and Middle East operators, the use of the Commando PUREair system was extended with some interface modifications to the MIL Mi-8, and then to the Mi-24 and Mi-17 families.

The PUREair system fitted for the Mi-8/17/24 differs only in the mounting arrangements for attaching the units to the helicopter fuselage, the scavenge fans, and the option for the addition of mesh screen cones.

The Pall PUREair designed for the Mi-8 has a significantly lower power penalty than the OEM dust protection unit (DPU) separators. This is due to the uniform flow and pressure distribution it creates at the compressor entry plane.
