DART Aerospace has announced that Kallax Flyg of Sweden has provided a letter of intent to order two PA100 PUREair engine protection systems for their AS350 family of helicopters once the system has received EASA certification.

The PA100 PUREair System, co-developed by Pall Aerospace and DART Aerospace, is a totally redesigned, reengineered, and retested engine air protection system that takes the capabilities of its EAPS predecessors to the next level. Featuring Pall's latest PUREair technology, the new system is self-cleaning and virtually maintenance-free, unlike other filtration systems qualified for this aircraft. The PA100 PUREair system will provide the highest level of helicopter engine protection while offering a 2% gain in engine power over conventional inlet barrier filters.

“At Kallax Flyg, our everyday operations range from commercial air transport to aerial work in the Swedish mountains”, explained Jim Lindqvist, maintenance manager at Kallax Flyg. “With these specific missions in mind, we require a reliable, cost-effective and easy to install engine protection system that will allow us to fly in falling, blowing, and re-circulating snow with our AS350 aircraft during our winter operations and at the same time, clean the inlet air during our summer operations. We believe the PA100 filtration system is the solution to our needs.”

This next generation system utilizes the latest advances in Pall Aerospace technology; including 3D computational fluid dynamics (CFD) optimized system design and innovative nano-material technologies. The PUREair vortex tube works in all weather conditions, including ice, snow, heavy rain, and salt spray, and the system will be certified for inadvertent entry into icing conditions.

After securing Canada STC approval, DART and Pall will seek FAA, EASA and ANAC STC approval.
