Cabinet
The fan is made of galvanized steel sheet, the casing is fitted with flanges for fixing to the square pipe. There is a revision cover on the casing, which, when removed, gives access to the impeller.
Circulating wheel
The impeller is radial with forward curved blades and is made of galvanized steel plate. It is statically and dynamically balanced.
Motor
is asynchronous with a resistive armature. The motors are fitted with a thermal fuse as standard and the windings are in a moisture-proof finish with Class F insulation. The sealed ball bearings are grease-filled for life. Protection rating IP55.
Rotation direction
is indicated by an arrow stuck on the housing. The direction of rotation must be checked after commissioning, if the direction of rotation is reversed, the phase sequence must be changed.
Cabinet
is directly on the motor and can be accessed by removing the inspection cover.
Speed control
is carried out by electronic or transformer regulators by changing the voltage. We preferably recommend transformer regulators. Frequency converters can also be used.
Mounting
in each position of the fan, with regard to the revision activity and the possibility of removing the revision cover preferably with the motor axis vertical.
Instructions
The fans are suitable for general air handling applications where the low installation height of the fan is advantageous. Due to their enclosure and higher operating temperature, the fans are suitable for ventilation of restaurants, hospitals, sports halls, warehouses and production areas.
