    Description
    APPLICATIONS
    • Supply and exhaust ventilation systems for various premises with a limited mounting space. 
    • Designed for connection with 400*200, 500*250, 500*300, 600*300, 600*350, 700*400, 800*500, 900*500, 1000*500 mm rectangular air ducts.
    DESIGN
    • The fan casing is made of galvanized steel.
    		  
    MOTOR

    • The impeller with forward curved blades made of galvanized steel is powered by 4- or 6- pole external rotor asynchronous motor.

    • Such modification ensures high air flow capacity and relatively significant differential pressure.

    • For thermal overheating protection the thermal contacts with leaded outside terminals are incorporated in the motor winding for connection with the external protection devices. 
    • The motor is equipped with the ball bearings for long service life.
    • For precise features, safe operation and low noise, each impeller 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 fans are designed for inline rectangular air duct mounting and require no special fixing in case of direct connection.
    • In case of connection through the flexible connectors the fan is fixed to a building by means of supports, suspension brackets or fixation brackets. 
    • The fans can be mounted in any position with respect to the pointer direction on the casing.
    • Access for the fan maintenance shall be provided.
    • The fan is powered through the external terminals.
    • The casing is provided with the removable access door for maintenance.
