  • Designation key
  • Exhaust ventilation systems for commercial, office and other public or industrial premises for extraction of air with temperatures up to 40 °C.
  • Direct air exhaust is provided.
  • Steel casing with polymeric coating ensures motor protection against direct humidity exposure in case of the unit outdoor mounting.
  • The fan bottom has a bird and rodent proof guard. Air is exhausted vertically down.

The motor is protected against direct ingress of moisture and foreign objects

  • The units are equipped with high-efficient EC motors with an external rotor and an impeller with backward curved blades.
  • These state-of-the-art motors offer the very best in energy efficiency today.
  • EC motors are characterised with high performance and optimum control across the entire speed range.
  • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
  • The fan is controlled with the external control signal 0-10 V (capacity control is performed depending on the required level of productivity, temperature, humidity, pressure and other parameters).
  • Should the control value factor get changed, the EC motor changes its speed and the fan boosts as much air flow to the ventilation system as required.
  • Maximum fan speed does not depend on the available current frequency and is suitable for operation both at 50 and 60 Hz.
  • Several fans can be integrated into a single computer-driven control system.
  • Custom designed software provides high accuracy control of the fans integrated into a network.
  • The fan is designed for outdoor surface wall mounting and connection to round duct of the respective diameter.
  • The fan is powered through the external terminals.
  • Electric connection and mounting shall be performed in compliance with the manual and wiring diagram provided in unit operation manual.
