The Alpha Series Discharge Axial Fans’ construction specifications feature Cowls of UV-stabilised plastic or fibreglass. Bird mesh guards are fitted as standard, except when fitted with shutters and the steel components have a corrosion-resistant finish.
Shutters are fitted as an optional extra. When fitted, it is important to make sure that the flap hinge points down the slope of the roof. Shutters are not recommended on 8-pole Discharge Axial Fans below size 638.
The Alpha Series Discharge Axial Fans feature horizontal exhaust discharge and are also available in supply air mode if required.
