Air Filter System

The air filter system can be adapted to
suit different operating conditions by
installing different filters. Changing a
filter is accomplished quickly and simply.
The saw comes standard with either a
fabric filter or a fleece filter.
Fleece filter
For normal operating conditions and dry
work areas.
Fabric filter
For extremely cold operating conditions
(e.g. in powder or drifting snow or frost).
