You may not always realise it, but outside air is not always clean either. ‘Fresh’ air can be polluted by, for example, pollen, (fine) dust, exhaust gases, bacteria and mold spores. IntrCooll always purifies incoming fresh air before it is blown into the production area. In colder periods we can also guarantee a dust-free indoor climate, by filtering the air recirculated with the Heat Reclaim module. The degree of filtering depends on the chosen filter class.
