£ 5,270.33 (excl. VAT)

£ 6,324.40 (inc. VAT)

Range of cylindrical cased axial flow fans with motor located externally to the fan casing and incorporating a belt driven impeller making this range suitable for continuous operation up to 120ºC.

Max Duty - 44,00 m3/hr
Max Absorbed Power - 7,500 W
The casings are manufactured from high grade rolled sheet steel protected against corrosion by cataforesis primer and black polyester paint finish.

The drive system consists of an industrial poly V-belt drive pulley system which is enclosed within metal protective guard.

ATEX versions available.
These fans are often used for paint shops etc as the motor is out of the airstream.
