2. DESCRIPTION OF MACHINE
2.1. PRODUCT DESCRIPTION
Parking garage fan units from the EC-ITF©series with unilateral extraction have been developed for a room in a
building whereby, in the case that air pollution is present, a directional air ow can be initiated through which the
polluted air (cold smoke, etc.) can be extracted from the room.
The air is drawn up by via the grate through the motor/impeller combination and blown out via the outow
opening.
The fan unit is equipped with two backward inclined impellers each with an integrated EC, external rotor motor.
The applied EC motors are IP 54, ISO B, S1. The connection voltage is 200~240/1/50/60. The power supply
connection is through an outer terminal box (OTB1) and the speed control including maximum airow connection
is also through another outer terminal box (OTB2). The fan must always be properly grounded.
The fan unit is intended for installation on a ceiling/wall whereby it is not permitted to have
the fan unit arranged (vertically) blowing out upwards. Safety precautions must comply with
the requirements contained in EN 292.
