Boost your air quality

The compressed air line filters eliminate oil, dust, and other contaminants, optimizes installation, and achieves a superior final product quality.

Save costs

Thanks to high quality components, higher uptime and longer lifetime are ensured while having great serviceability.

Undemanding maintenance

The filters are compatible with any compressor technology and can be easily installed into an existing installation. There’s an optional pressure drop device (indicator or gauge). The cartridges can be easily replaced.

How clean is your compressed air?

Atmospheric air naturally contains several impurities such as dust, various forms of hydrocarbons and water in the form of humidity. Once the air is compressed, their concentration is increased. As a result, these contaminants find their way to the compressed air circuit, causing wear and corrosion to the downstream equipment. MARK air line filters remove these contaminants from the compressed air.

MARK filters keep your air distribution network in optimal shape!

In any compressed air net distribution it is a must to install one or more filters. As a result, an improved air quality is achieved which benefits your complete compressed air network, including the downstream dryers, air pipes and pneumatic tools. Depending on the application you may need to filter your air in different stages to prevent saturation of the elements, keep your air quality and avoid pressure drops.


Extend your filter range with a water separator

The new water separators integrated into the compressed air filtration range combine proven centrifugal technology with a new innovative housing design to deliver market leading water removal efficiencies, eliminating 99% bulk water and guaranteeing continuously low differential pressure.
