Porvair Filtration Group’s Ashland, Va. facility is manufacturing last-chance filters for the aerospace industry. Last-chance filters and screens in aircraft fluid systems provide critical point-of-use protection for contamination-sensitive components, performing a complementary role to main system filters. Last-chance filters are designed to remove and retain contamination such as machining chips, burrs, wear debris and fluid breakdown products introduced during operation or downstream of the main system filters.
“Even something as simple as sand ingestion can easily reduce an engine’s time between overhauls by 50 percent or more,” said Bob Stenberg, business development director for Donaldson (Booth No. 2847). The company specializes in the design and development of filtration systems and has recently received an FAA STC for an inlet barrier filter (IBF) system for the Bell 430.
Donaldson Co. announced yesterday that it has acquired Aerospace Filtration Systems (AFS) of St. Louis, Mo. The deal, which was inked on Tuesday, calls for AFS to become a wholly owned subsidiary of the worldwide supplier of filters and support. The marriage isn’t new for the two companies; they were selected as a team last year to supply integral barrier filters (IBF) for the Bell 429 and the recently canceled 417.
