Dayton upblast ventilators are designed to provide a stable stream of clean air for reduction in overall air conditioner strain, cooling attics, laboratories, preventing moisture & heat build-up and for exhaust ventilation from foundries, warehouses and manufacturing facilities. These exhaust vents feature heavy-gauge galvanised steel housing for resistance against harsh weather & industrial environment and come equipped with reinforced edges & bolted seams for additional strength. Dayton upblast ventilators feature die-formed galvanised steel drive frames that offer a rigid platform for drives, motors, bearings and shafts. The fabricated steel propellers of these vents have steeply pitched blades to ensure minimum noise levels, integral butterfly dampers prevent unwanted backdrafts and magnetic latches minimise damper flutter when these ventilators are not in use. Built-in lifting lugs and removable windbands allow easy installation and inspection, respectively.
