    • The centrifugal impeller with backward curved blades is powered by the single-phase motor with external rotor and overheating protection with automatic restart.
    • The motor is equipped with ball bearings for long service life designed for at least 40 000 hours. 
    • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
    • Motor protection rating IP 44.
    SPEED CONTROL
    • Smooth or step speed control with a thyristor or autotransformer speed controller. 
    • Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.
    MOUNTING
    • The fan is designed for outdoor surface wall mounting and connection to round duct of the respective diameter.
    • The fan is powered through the external terminals.
    • Electric connection and mounting shall be performed in compliance with the manual and wiring diagram provided in unit operation manual.
