  • Supply and exhaust ventilation systems for various small premises with a limited mounting space.
  • For connection with round ducts from 80 to 200 mm in diameter.
  • Various casing modifications with the number of inlets from 1 to 6 enable using one fan for air exhaust from several premises simultaneously. This makes ventilation system mounting much easier.
  • The fan casing is made of steel with polymeric coating.
  • The minimum casing height enables fan mounting in a limited space. 
  • The removable cover provides free access to the motor, ensures easy mounting and enables the fan and air ducts maintenance without dismounting.
  • The centrifugal impeller with backward curved blades for high pressure is powered by means of the single phase three-speed motor with external rotor.

  • The specially designed smart impeller with forward curved blades maintains constant air flow by means of controlling the motor speed depending on air resistance in the air duct. 

  • Motor is equipped with incorporated overheating protection with automatic restart and 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.
  • The motor speed changes automatically as a function of ventilation system resistance thus ensuring the constant air flow.
  • Motor speed changes automatically as a function of the ventilation system resistance.
  • This ensures constant airflow.
  • If a three-position switch is additionally installed, three speeds of motor can be controlled manually. 
  • For smooth or step speed control a thyristor or autotransformer controller can be applied.
  • Several fans can be connected to one controller in case the total power and operating current do not exceed the controller rated values.
  • Mounting at any angle to the wall is performed with the fastening bracket supplied with the unit.
  • The fan is powered through the external terminal box.
  • Electric connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
