Donaldson Aerospace & Defense's [Booth 2400] Universal Filter Module (UFM) has been certified by the FAA for installation and use on Sikorsky Aircraft S-61 and H-3 helicopters.
The FAA issued the Supplemental Type Certificate (STC) for an Inlet Barrier Filter System (IBF) to The Coulson Group of Companies, which co-developed the S-61/H-3 installation along with Donaldson. The UFM is a subsystem of the IBF, which will protect engines on those helicopters from 99% of airborne contaminants with minimal loss in hover performance. Based in Port Alberni, British Columbia, Coulson operates S-61s in Azerbaijan, British Columbia and Australia's state of Victoria. The Coulson Group obtained a Canadian STC for the system from Transport Canada in mid-2015.
AAR Airlift ordered four systems and plans to purchase five more units plus sparing for use on its nine S-61N helicopters currently operating in Africa.
The products will be on display during Heli-Expo at Donaldson's booth.
