  • The VUE P3 A3/A4 air handling units are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
  • During the operation process the extract air heat is transferred to the supply air through the plate heat exchanger.
  • The units are used in ventilation systems installed in various premises that require reasonable energy saving solutions and controllable ventilation systems.
  • All models are designed for connection to ø100 and 150 mm round air ducts.
  • The single-phase three-speed motors with an external rotor and an impeller with forward curved blades.
  • The motors have an integrated overheating protection with an automatic restart.
  • The casing is made of polymer-coated steel panels, internally filled with polyurethane foam layer of 5 or 10 mm for heat- and sound-insulation.
  • The plate enthalpy cross-flow heat exchanger with heat recovery efficiency up to 87 %.
  • The applied heat exchanger enables not only heat but also humidity recovery, which helps maintaining an optimum humidity level.
  • In warm seasons the heat exchanger operates to cool down and dehumidify the supply air. In cold seasons the heat exchanger operates to warm up supply air and to humidify it
  • The recovered humidity and heat are transferred to the supply air flow.
  • The air streams are fully separated within the heat exchanger and the microbes and smells are isolated.
  • Two integrated panel filters with filtering class G4 and F8 provide efficient supply air filtration.
  • Extract air is cleaned by an integrated G4 filter.


  • The unit is equipped with an integrated control system, a mechanical three-speed speed controller P3-1-300 or a sensor three-speed speed controller SP3-1, and a power cable with a mains plug.
P3-1-300 SP3-1
  • The service side of the unit is equipped with a removable hatch for filter and heat exchanger cleaning and replacement operations.
  • The control unit is positioned inside the unit casing.
  • The power cable and grounding cables are connected to the control unit via the cable glands placed at the side of the unit.
  • The heat exchanger freeze protection operates as follows: in case of freezing danger determined by the temperature sensor, the supply fan is turned off to let extract air warm up the heat exchanger.
  • Due to a low casing height the air handling units are a perfect solution for space-restricted installation above suspended ceilings.
  • The unit mounting position must provide access for service maintenance.
