Description

DESCRIPTION	CASING
The fan unit provides filtration, heating and supply of fresh air to premises with the air flow from 200 up to 1500 m³/h.	The casing is made of aluzinc with internal heat- and sound-insulating 25 mm layer of mineral wool.
FILTER	HEATER
Integrated panel G4 filter ensures sufficient supply air purification.	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 overheating thermostat with automatic restart.	The motor ball bearings are maintenance-free and are designed for at least 40 000 hours service life.
CONTROL AND AUTOMATION
Integrated control and automation system for air flow control and setting supply air temperature.	The unit may be controlled from the external control panel fixed on 10 m wire delivered as a standard.
CONTROL AND PROTECTION FUNCTIONS
switching the unit on/off; maintaining supply air temperature set from the control panel by means of triac heating capacity regulation; 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.
