Brackett BA-117 Filter Assembly

This Brackett polyurethane air filter element has been designed to provide maximum dust collecting efficiency, non-restrictive air flow, and economical element replacement, while maintaining a lightweight filter. The element has been treated with a distinctive treatment called a wetted agent and is approximately 98% efficient. The wetted agent is an accompaniment in the efficient capturing of dust. In addition, the element has received a fire retardant treatment. For the above reasons, replace the element each 200 hours of use/12 months or when 50% covered with foreign material. DO NOT WASH AND REUSE.

NOTE: The expected shelf life of Brackett elements stored in their original packaging and out of direct sunlight is as follows: 4 years from date of manufacture listed on the front of the element packaging (EX: MFG MONTH/YEAR). This allows the element to be installed on an aircraft at the end of its shelf life.

Step 1: Install filter using the same procedure as with the original filter.
STEP 2: Apply service decal to or near the filter canister. PLACE SO IT IS READABLE.
Step 3: NOTE: After initial installation of filter assembly, fill out FAA Form 337 for return to service. On future replacement of parts this form will not be required.
Servicing: To replace element PN BA-17, remove inner screen from outer screen discard foam element. Clean both screen assemblies with solvent or warm water and detergent soap. Install new element between the two screens, making sure 1/4 inch of foam extends out both ends of screen. Reinstall filter assembly.
