Transport Canada has certified Inlet Barrier Filters (IBFs) from Donaldson Aerospace & Defense for installation on Airbus AS350 B3, EC130 B4, and EC130 T2 helicopters. The IBFs keep contamination, including dirt, dust, salt and foreign objects, from degrading the performance and reliability of helicopter engines.
According to Donaldson turbine engine components are life-limited parts, but without advanced filtration seldom reach their design life.
Donaldson offers 16 Transport Canada certified filtration systems for a range of Airbus, Leonardo, Bell, MD Helicopters and Sikorsky helicopters; 14 are certified to operate in falling and blowing snow conditions.
