Casing
Casing manufactured from galvanised sheet steel. Motors and impellers are mounted in the cover to make cleaning and maintenance easier.
Motor
Voltage controllable external rotor motors.
Impeller geometry
Radial impeller with forward curved blades.
Output control
Speed controllable via voltage reduction using a transformer, or controllable with a frequency converter by using an all-pole effective sinusoidal filter.
Motor protection
Integrated thermal contacts with cables for connection to a motor protection switching device.
