Desiccant rotor air dehumidifiers  

Select your need


DFRA desiccant rotor air dehumidifiers remove moisture from the air and control humidity in both commercial and industrial applications. They work by means of a high performance silica gel desiccant rotor that attracts and retains water vapour easily and effectively. In this way, when air loaded with vapour or humid particles enters the wheel, the desiccant material filters it, retaining all the humidity and expelling it again as dry air. 

These desiccant rotor air dehumidifiers are characterised by their energy efficiency as they work with very low consumption and high performance in air filtering. In addition, at Fisair, we market safe equipment that complies with safety, health and hygiene requirements, so the rotors that incorporate our dehumidifiers are tested against bacteria and fungi.
