Max Power Absorbed - 0.120kW
Suitable for operating temperatures up to +200°C
DBA @ 3m - 48dB Inlet

High Temperature
Class H motors out of the airstream are not effected by contaminates in the ventilated air. Suitable for elevated temperatures of up to 200°C.
Efficient Performance
High Efficiency Adjustable pitch aerofoil impellers are provided with blades made from high quality pressure die cast aluminium.
Weather Resistance
The fans are suitable for external mounting as standard.
Long Life
Motor is isolated from hot and contaminated air, prolonging the life of the fan. Motors are foot mounted, totally enclosed fan cooled, IP55, with sealed for life bearings with a standard industrial paint finish and Class H insulation to EN 60034-5.
Impeller
Adjustable pitch aerofoil impellers are provided with blades made from high quality pressure die cast aluminium (LM6), natural finish. Impellers are factory set at an angle to provide maximum performance. The hubs are manufactured from die cast aluminium alloy (LM24). Assembled impellers are to be dynamically balanced to ISO 14694 Grade G6.3.
