The IBF system for A119 Koalas features flat filter assemblies with an integral bypass design. A filter maintenance aid allows for on-condition status checks between established cleaning intervals, eliminating unnecessary service. No restrictions are imposed for flight in falling or blowing snow or with visible moisture in non-icing conditions. The system is already in use by Koala operators performing law enforcement, firefighting, utility and maritime surveillance missions across the globe.

Barrier filtration systems have proven their ability to remove over 99% of expected engine inlet contamination and provide improved performance compared to traditional inertial particle separator type designs. AFS and its parent Donaldson Company lead the industry with innovative and state of the art inlet protection technologies.

AFS is the industry leader in the design, development and manufacture of high-performance engine IBF systems for commercial and military propulsion systems. AFS manufactures certified IBF solutions for the AgustaWestland A119 Koala, Bell 205A1/UH-1H, 206B, 407, 206L-3/4, 206L-1(C30), MD Helicopters MD 369 (MD 500H/D/E/F Series), and Eurocopter AS 350 B/BA/B1/B2/B3 (AS 350D/SD/SD2-Soloy STC).
