Cabinet
It is made of sheet steel, electroplated and coated with grey epoxy lacquer. The motor is outside the airflow in a duct located perpendicularly in the fan housing. The motor is cooled by a fan, which is part of its construction.
Running wheel
is cast entirely in Al alloy. The impeller is statically and dynamically balanced and has a red epoxy lacquer finish.
Motor
is asynchronous, short armature, with F class insulation, grease filled ball bearings for life. The motor has its own cooling fan. IP55 protection.
Square box
is included with the motor.
Speed control
Conditions under which speed control can be used, please consult our technical department. The fan and drive system has its own cooling dependent on the engine speed. Reducing the speed may, under certain circumstances, reduce the durability of the bearings and grease packing of the moving parts of the fan. Speed control is possible without additional measures at supply air and ambient temperatures up to 40 °C.
Rotation direction
is indicated by an arrow on the fan housing.
Mounting
Fans are recommended to be mounted horizontally, with the ventilation duct vertically to ensure cooling of the motor, due to bearing life. If forced ventilation of the duct with the motor is provided, mounting in another position is possible.
Instructions
Ventilators are suitable for exhausting hot gases. Please ask for information on delivery conditions and delivery times.
Notices
Alternatively, motors are supplied with a thermal fuse in the winding. In this case, the wiring diagram supplied with the fan in the documentation must be used. The thermal fuse must always be plugged in, otherwise the motor is not eligible for warranty repair.
