Feb. 13, 2012, St. Louis, Mo. - Donaldson Aerospace & Defense will display an innovative self-contained universal filtration system at Heli-Expo 2012, Exhibit 8451.

The Universal Filter Module (UFM) has been launched with its first application on the Sikorsky S-61; this is the first ever available IBF for the aircraft.
The UFM features a low-drag filtration solution mounted forward of the engine inlets, featuring three filter elements easily accessible and removable for service.  These filters include a 4,500-hour service life.  A translating forward-facing dome for emergency bypass provides protection from airborne solid particulate.
The scalable system, developed in conjunction with the Coulson Group, has the potential to be adapted for a wide range of heavy, twin-engine helicopters, according to Michael Scimone, President of Donaldson’s St. Louis office. A successful flight test program has been completed and the development team is evaluating next steps, including certification for commercial applications.
“Our UFM was developed in response to an industry need and customer requests – tremendous potential exists within this market segment,” Scimone said. “As the industry’s filtration leader, this development effort underscores Donaldson’s long-standing commitment to technology advancement.”
