Description

The fan unit provides filtration, heating and supply of fresh air to premises with the air capacity from 200 up to 1500 m3/h. All the models are compatible with 100, 125, 150, 200, 250, 315 mm round air ducts.

Casing

The casing is made of aluzink with internal heat- and sound-insulating 25 mm layer of mineral wool.

Filter

G4 filter ensures high degree of supply air purification.

Heater

Electric heating battery is designed for supply air heating during winter and off-season time.

Fan

Centrifugal fan with backward-curved blades and built-in thermal overheating protection with automatic restart. High-powered motor modification (VPA-1) is available for some standard sizes. The fan motor and impeller are dynamically balanced in two planes. The motor ball bearings are maintenance-free and are designed for at least 40 000 hours service life.

Control and automation

The supply unit is available in two modifications:

  1. No control. Customer-defined and customer-selected automation system.
  2. Integrated control and automation system to ensure control of air capacity, setting temperature of supply air, filter clogging degree etc. In addition the automation system provides overheating protection of heating elements. The remote unit control is effected by means of the external control unit with 10 m wire supplied as a standard.
Control and protection functions
  • remote switching the unit on and off
  • setting of required supply air temperature and maintaining selected temperature mode by means of the control panel (electric air heater control by means of the optosymistor)
  • fan speed control by means of the control panel (3 speed modes)
  • working-out of the required patterns during the unit switching on and off
  • the unit daily or week timer operation
  • active overheating protection of heating elements
  • disabling electric air heating battery operation when the motor is not running
  • electric heater overheating protection by means of two thermostats
  • filter clogging control though the differential pressure sensor
  • actuating the air damper
  • relay input from an external sensor (humidistat, CO2 sensor, motion sensor) to switch the fan to maximum speed
  • input for alarm fire fighting signal
Mounting

Air supply unit can be mounted on the floor, attached to a ceiling with a seat angle with anti-vibration mounts or attached to a wall by means of the brackets. The unit can be mounted either in service spaces (balcony, storage room, underground floor, roof space etc.) or in the main space by placing the unit above the suspended ceiling or in the pocket. The unit can be mounted in any position except for the vertical one with vertical air downstream because tubular heating elements are not allowed under the fan. Free access to the unit shall be provided for maintenance and filter cleaning. The service panel is placed on the top. The control block is on the right.
