ATEX WALLAXIAL FAN
APPLICATION
ATEX Plate Mounted Axial Flow Fans suitable to exhaust/supply air in presence of chemical processes, water and sewage treatment, material and gas waste, dust and paint extraction, battery room ventilation and refrigeration, e.g. ambient in which high air volumes are needed. Note: the correct ATEX protection grade must be selected according to the type of Hazardous Area.
FEATURES & BENEFITS
