Results from oil spectrographic analysis showed the Brackett filter to be consistently more successful in providing superior engine protection, and this is further proved by fewer spark plug problems and longer TBO's. The unique polyurethane filtering medium retained more foreign particles and is more resistant to sand abrasion than the coventional filters now in use.

Brackett air filters are easy to replace and les expensive to service than conventional filters. Remove the disposable polyurethane element and replace with a pre-wetted element. You need not replace the entire filter assembly during regular maintenance service.

The new "patent" oil wetting agent formula is extremely stable, resistant to chemical change, non-toxic and is fire-retardant. In addition it maintains a favorable air flow with a minimum air restriction throughout its service life. THIS IS A THROW-AWAY ELEMENT.

Bracket filters are FAA-PMA approved.
