The H425 helicopter, part of the Z9 series, is the Eurocopter Dauphin helicopter built under licence. It can be used in a variety of roles such as; Emergency Medical Service, Search and Rescue, Law Enforcement, Fire-Fighting, Border/Coast Patrol and Offshore Transport. 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, resulting in:
Safer operation by protecting against FOD, ice, snow, and sand
Increased operational availability
Protection against engine erosion
Reduced maintenance and operational costs

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.
A certified upgrade is now available which provides a dramatic increase in dust separation efficiency compared to the original PUREair unit designed many years ago
The H425 PUREair system is based on the original design for the Eurocopter Dauphin but it uses the latest advances in design techniques and material technologies to provide a significant performance improvement.
First design developed for AS365 Dauphin helicopter
Improved design for AS365 Dauphin to reduce bleed air down to 12g/s
New design concept for H425 helicopter.
Higher sand/dust separation efficiency.
Optimised ejector design means reduced power loss
Revised inlet duct and filter profile to improve overall performances.
*The QB0935/6 PUREair system is not yet certified on the Eurocopter Dauphin family, but it is Pall’s ambition to achieve this.
