  • The unit VA is a fan-filter block enclosed in a compact sound-insulated casing.

  • The VA unit provides high pressure combined with low energy demand due to the impeller with backward curved blades.

  • The unit is suitable for supply and exhaust ventilation applications.
  • Steel casing covered with aluzinc coating internally filled with 50 mm heat- and sound-insulating layer made of mineral wool.

  • The units are equipped with a high-pressure radial fan directly driven from the external rotor motor with backward curved blades.

  • The fan motor has integrated thermal contacts for connection to an external protecting device.
  • The unit is suitable for use both with and without filter as a simple fan. The replaceable filter block is an optional item and is not included into the unit delivery set.

  •  All the units may be equipped with a replaceable G4 panel filter, refer Accessories.
  • The unit is mounted to the air duct in any position.

  • The unit is suitable for installation in utility and main premises behind the false ceiling, in the recess or directly in the room.

  • The fan electric contacts are leaded to the terminal block located in the terminal box.



Type Replaceable filter Filter type
VА 01 SF PА/VA 01 Е G4 panel filter
VА 02 SF PА/VA 02 Е G4 panel filter
VА 03 SF PА/VA 03 Е G4 panel filter
VА 04 SF VA 04 Е G4 panel filter


  • The fan speed is controlled by the external triac, autotransformer or frequency three phase speed controller, refer RSAVFED).

  • To disable uncontrollable air flow when the fan is off and in case of power failure it is recommended to install the air damper with a return spring from outside behind the unit.

  • For attenuation of sound generated by the fan it is recommended to install the duct silencer (refer SR) from inside before the unit.

  • For vibration absorbing it is recommended to install the flexible anti-vibration connectors (refer VVG) on both sides of the unit.

  • For control of the filter clogging degree it is recommended to install the differential pressure switch (refer DTV 500).
