Our long-life air filter systems are extremely durable and feature high quality seals and materials – protecting your tool for longer and to a high standard.
When an engine is running it continuously needs air for the combustion process. This air passes through a filter before it reaches the engine to guarantee that the combustion process runs as smoothly as possible, and to keep wear and tear to a minimum. This process filters out unwanted particles such as concrete dust, wood splinters and other fine debris from the surrounding air and to prevent them from entering the engine, where they could easily cause damage. Many STIHL chainsaws and all STIHL cut-off machines include an innovative long-life air filter system to further reduce this risk.
Most STIHL chainsaws have an innovative long-life air filter system with routing to take the strain off the downstream filter elements. It works like this:
STIHL professional tip: For some chainsaw models you can upgrade your standard fleece air filter to the HD2 air filter. It comes in three variants to fit different chainsaw models
STIHL cut-off machines all have a long-life air filter system that includes cyclone routing, a paper filter, and a fine dust filter. The innovative cyclone routing system means reduced need for daily filter cleaning and a much longer filter service life. This is how the air filter system works in detail:
Long-life air filter systems offer a whole host of advantages.
