Donaldson is introducing two new products to its line of helicopter inlet-barrier filters (IBF). Inlet filters for the AgustaWestland AW109 Power and Grand and for the Eurocopter EC135 are slated for certification this year. Donaldson IBFs are operating around the world, from flight operations in Nepal near Mount Everest to the Sacramento Valley of California, protecting helicopter turbine engines during crop-spraying sorties.

Airborne law enforcement is an especially active user of Donaldson IBFs; In the hot, dusty air of Arizona several agencies, including the Phoenix Police, the Maricopa County Sheriff’s Department and Arizona Department of Public Safety, perform missions ranging from apprehending criminals to rescuing stranded mountain climbers.
