Dayton exhaust fans pull out odours, moisture and fumes from inside to outside of a vent in warehouses and offices. They have galvanised steel construction with aluminium propellers for corrosion resistance, durability and withstanding a maximum ambient temperature of 104 degrees F. These fans are designed such that the motor is directly connected to the fan through shafts or axles, thereby increasing energy efficiency. They feature intake guards that prevent large obstacles or debris from getting into the fan blades. Selected models come with a speed control option for controlling the speed of exhaust fans. Choose from a wide range of these exhaust fans, available in motor speeds of 1650 and 1772 rpm.
