  • 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.
  • Single-phase one-, two- or three-speed motor with external rotor and centrifugal impeller with forward curved blades of galvanized steel.
  • 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 IP44.
  • For single-speed models, smooth or stepped speed control is provided by means of an external thyristor or autotransformer controller (available upon separate order).
  • The Duo two-speed models are controlled by an external switch for two-speed fans (available upon separate order).
  • The three-speed models X3 are controlled by an external switch for multi-speed fans (available upon separate order).
  • 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.
Easy access to motor without fan dismounting External terminal box for power supply
