Axial Fan Unit
​
Harvest two stage axial fans are available as standard from 3kW (4hp) motors up to four 18.5kW (25hp) motors.
These standard units are supplied in heavy duty
dip-galvanised casings with cast aluminium impellers. High outputs per horse-power and the contra-rotating impellers will develop pressure equally as high as a similar output centrafugal fan unit.
For applications where there is a limit to electricity supply 'Harvest' two stage in line axial fans are the obvious choice. Special situations can be considered where extremely high back pressure or high outputs are required.
​
Silencers
​
Silencers are available for the range of Harvest fans fitting both centrifugal and axial models.
Available in standard form and also with internal pod fitted for even greater efficiency. silencers are one meter
long as standard and are easily attached to the inlet of both types of fan.
Extraction Fan Units
​
G.E.V.E Gable end extraction and ventilation units consisting of 900mm diameter reversible fan units with mounting plate and external cowl which can be supplied insulated and fitted with external silencer if required for noise sensitive areas.
