Description
Overview:
The Screw-Active Filter is a dedicated fastener for securing the air filter assembly on Husqvarna and Jonsered chainsaws. Built from robust metal for long service life, it keeps the filter firmly seated to maintain a reliable seal, helping prevent dust and debris from entering the intake.
