Flextraction has introduced a range of ventilation fans, able to extract smoke and fumes up to 400C for up to two hours.

The three-phase 230/400V 50Hz fans are designed to vent industrial kitchens, educational centres, storage buildings, inside and outside fire-danger zones in public car parks, garages, bodyshops and on construction sites.

The fans range from THT long-cased axial fans, including individual THT/ATEX fans and duplex extraction units with ATEX certification, and CJTHT and CJTHT/ATEX extraction units with soundproof boxes, to THT/IMP single-direction or reversible long-range impulsion fans in circular, rectangular or oval designs for smoke extraction meeting EN-12101-3-2002 certification.

For working inside fire-danger areas, the ATEX-certified long-cased axial fans with impellers ranging from 40-125cm (d) have an aluminium strip to prevent sparks, meeting EN 14986:2006 specifications, and incorporate a Class-H motor with one or two speeds depending on the model selected.

The long-range impulsion fans have variable-cast aluminium impellers for optimum impulsion and deflectors to increase the airflow range on the impeller side as well as silencers with thermal and acoustic insulation.

They can supply a maximum airflow ranging from 2130-64,850m3/hr depending on the model selected.

Depending on the floor layout, height and location of the fans, Flextraction can design and supply the extraction-duct systems and calculate the load losses.
