HiFEK roof extractors are efficient, energy-saving and silent extractors for office, commercial, public and residential buildings.
The airflow ranges of the new HiFEK ECO roof extractor are divided more evenly when compared to previous models. Our wide range of roof extractors covers every need, so you can produce better conditions to your site while saving energy – not forgetting a lower carbon footprint.
The best way to install HiFEK is to use a HiFEP installation chimney, the standard casing of which is manufactured from hot galvanised steel sheet. Installation accessories are included in the standard delivery. HiFEK roof extractors are easy to service, and thanks to their structure, the duct and the extractor are also effortless to clean.
