Description
APPLICATIONS
  • Supply and exhaust ventilation systems for various premises with a limited mounting space. 
  • Designed for connection with 400x200, 500x250, 500x300, 600x300, 600x350, 700x400, 800x500, 900x500, 1000x500 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-, 6- or 8- 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.
