Brackett filters are FAA/PMA approved and STC-SA71GL, STC-SA693CE, and STC-SA12CE approved
Polyurethane as the filtering media combined with Brackett's patented "wetting agent" will give your engine protection from dust and dirt to prolong engine life and cut maintenance. The Brackett polyurethane aircraft element can be changed without replacing the complete air filter assembly. Now induction systems, cylinders, and combustion chambers can be kept almost totally free of harmful contaminants with correct fitting of Brackett aviation air filters.
NOTE: Our STCs require the elements to be replaced every 12 months, regardless of the flying time, or more often as per service instructions.
