Belt Drive Exhaust Fans W/o Drive Packages, 20 Inch Blade

Dayton exhaust fans mount horizontally or vertically to pull out odour, moisture and fumes from inside to outside of a vent in commercial and industrial applications. They have galvanised steel construction with sealed pillow block bearings for load support to the rotating shaft, corrosion resistance, durability. They are capable of withstanding a maximum ambient temperature of 104 degrees F. These fans come without assembled belt drive packages that offer greater flexibility in terms of rpm speeds, as the motor is not directly in contact with the fan's moving parts. Choose from a wide range of these exhaust fans with 5 or 6 bladed propellers.
