Donaldson to supply engine air intake filters for new Cirrus SR22T aircraft

Donaldson Aerospace & Defense, a division of Donaldson Company (NYSE:DCI), announced today that the company has initiated a new OEM agreement with Cirrus Aircraft to supply engine air intake filters for the new Cirrus SR22T aircraft. Shipments began in June 2010.

Cirrus Aircraft selected Donaldson for its reputation of providing superior filtration technologies for the aerospace industry and for its ability to develop a tailor-made solution to fit this specialized application. "We're very pleased that Cirrus Aircraft has selected Donaldson air filtration technology for this state-of-the-art aircraft," said Sheila Peyraud, General Manager of Aerospace & Defense at Donaldson Company. "The Donaldson engine intake filter is manufactured using a fiberglass, synthetic media and is designed to provide maximum airflow to the engine in this high-performance aircraft."

The Cirrus SR22T is the newest member of the Cirrus SR22 family of composite airframe piston engine aircraft. The key feature of the four-seat airplane is the 315 HP twin turbocharged TSIO-550-K engine. Providing air to the engine is a redesigned cowl with new, dedicated NACA (National Advisory Committee for Aeronautics) induction inlets – one on each side of the lower cowl – which direct air flow into the dual Donaldson filters. This new system offers improved engine airflow and better performance.

Paul Brey, VP, Product Development at Cirrus Aircraft commented, "The Donaldson engineers went out of their way to understand our application and ensure that their product fit well and worked perfectly from day one. The Donaldson team's attention to detail and ownership of filtration aspects allowed the Cirrus team to focus on other areas of the aircraft development."
