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.
The UK’s Porvair Filtration Group is here at the Farnborough International airshow (Hall 4 Stand C1) exhibiting a range of its filters and other vital components for modern aircraft. The company is at the forefront of filtration and separation technology for a variety of markets. In the aerospace sector it is involved in a wide range of activities in contamination control of fluid and air management and control systems.
“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.
Corpair Supply, the component arm of Chesterfield, Mo.-based Avmats, can now clean, bubble point and flow check Falcon hydraulic filters. It also offers a complete set of exchange filters for the Falcon 10, 20, 200 and 50s. The company has more than 25 years of experience in heavy maintenance, sheet metal, avionics, engines, APUs, interiors and modifications.
In recent years, much has been made of the potential danger presented by the recirculation of aircraft cabin air that may be bearing viruses and bacteria.
UK-based Microgenix now says it has an answer that is close to 100-percent effective against harmful viruses and bacteria, has no moving parts and is light in weight and low in cost.
