Industrial fans for lab hood exhaust
Lab hood fans, usually Induced Draft fans, are used to create a negative pressure locally within the laboratory hood, to ensure the containment of potentially toxic fumes within the experimental environment and to extract, smoke and fumes to scrubber systems.
The requirement may be to deal with highly toxic or even explosive gases which demands fans built to the highest specifications including explosion-proof (ATEX) where the fan should not precipitate an explosion but will also withstand without rupture, gas ignition taking place with it. Some aggressive fumes and chemicals demand that the fan be constructed from corrosion resistant alloys.
