Pall PUREair System for Boeing CH-47 Chinook Helicopter

Fit and Forget Engine Protection

The Boeing CH-47 Chinook is the workhorse for the U.S. Army's military transport operations.  The multi-mission capability of this heavy-lift helicopter means it can be used for a wide variety of roles ranging from troop transport to disaster relief and medical evacuation.  However, these demanding missions also mean frequent landings on unprepared grounds away from the main base.

Pall's PUREair system is an ideal solution for such challenging conditions.

The system shields engine inlets from airborne contamination which results in:
  • Safer operation by providing protection against sand and dust, FOD, ice, and snow
  • Increased operational availability
  • Protection against engine erosion
  • Increased time between overhauls (up to 30 times more compared to an unprotected  engine)
On the CH47, there are two barrel-shaped modules fitted in front of the engine air intakes. These are located on rails to allow easy access for engine inspection. Pall has developed a complete installation kit comprising the PUREair modules, electrical kit, and structural reinforcement.

Certifications:

  • Service Bulletin SB459-60-2 Issue 3
For the CH47 helicopter, a number of winter trials were carried out, resulting in the certification of the PUREair equipment for cold weather flight.

Maintenance

There are no inlet barrier filters to replace or clean; the PUREair is a “fit and forget” system. As with all aircraft equipment, routine visual inspection is recommended. 

For additional information about this product, please contact your local Pall representative.
    The Pall PUREair solution is also 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.
