Block filter systems
Corrosion-resistant, passive exhaust air filter system against severe odors.

Product description
The COALSI block filter works completely current-free and uses natural airflow to channel odorous exhaust air through the filter mats. With a gas flow rate of approx. 200 m³/h, odors are effectively and almost completely neutralized - and that on a compact footprint of just 0.6 m².
At the heart of the eye filter are the COALSI hybrid mats, which, thanks to triple filtration, ensure thorough purification of exhaust air. The air is passed evenly through all filter elements and then removed cleanly — completely without electricity.
