Westcoast Saw Air Cleaner System is made from 65 PPI polyurethane foam and polyurethane flange. The 65 PPI polyurethane foam captures dirt and foreign particulates better than paper or gauze, thus offering superior filtration for your chainsaw.
FEATURES:
Flange is fully bonded during manufacturing to foam, decreasing any chance of separation.
