Abstract

The device has its upstream end connected to an air channel and includes a first elongated opening between its upstream and downstream ends for discharging supplied air via a curved, perforated front plate oriented in the air flow direction. A second elongated opening before the first opening is provided with a second perforated plate oriented in the flow direction and has an open area tapered towards the downstream end of the device.
