    Description
    APPLICATIONS
    • Supply and exhaust ventilation systems for commercial, office and other public or industrial premises.
    • For premises with high requirements to noise level we offer units in low-noise modification (VKMz…Q).
    DESIGN
    • The fan casing is made of galvanized steel. 
    		  
    MOTOR
    • The impeller with backward curved blades is powered by the single phase motor with external rotor and overheating protection with automatic restart.
    • Some standard sizes are available with high-powered motors (VKMS).
    • The motor is equipped with ball bearings for long service life designed for at least 40000 hours.
    • For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly.
    • Motor protection rating is IP44.
    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
    • Mounting at any angle to wall or ceiling is performed with fastening brackets supplied with the unit.
    • The fan is powered by means of the external terminal box.
    • Electric connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
