The Vertical Discharge Roof Fans are a heavy duty, weatherproof roof exhaust fan designed for the vertical exhaust of heat, steam, dust, smoke and explosive gases in a wide range of commercial and industrial applications. They are especially suited for situations requiring the air to be discharged high above the roof line.
The Vertical Discharge Roof Fan is available using adjustable pitch GRP (Glassfiber Reinforced Polypropylene) or cast aluminium airfoil impellers. The casing is fully welded mild steel construction with a hot dip galvanised finish. A weatherproof butterfly damper is attached to the fan to prevent rain ingress. The units are fitted with single-phase 240V or three-phase 415V heavy-duty motors of rugged construction, which incorporate sealed ball bearings to reduce operating noise. There is a comprehensive range available with fan diameters ranging from 300mm to 1500mm.
Features:
- Vertical discharge of airflow
- Hot dip galvanised casing
- Butterfly damper to prevent rain ingress
- IP55 motor
- GRP adjustable pitch blades
- External junction box
