Dayton exhaust fans pull out odours, moisture and fumes from inside to outside of a vent in commercial and industrial applications. They have galvanised steel construction for corrosion resistance, durability and withstanding a maximum ambient temperature of 104 degrees F. These fans come without assembled belt drive packages that offer 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, available in maximum airflow speeds of 11061, 14990 and 15488 CFM.
