This wall-mounted ventilation system provides fresh air from outside with a quiet, controlled, energy-saving, filtered electric blower inside the room. Fresh air from outside reaches the room by pressure compensation between outside air and inside air (differential pressure ventilation) when the fan is switched off.
It can be used continuously or with its timer function that starts the unit for a preset operating time (in hours). Once the operating time is reached, the fan automatically stops and restarts automatically at the last selected settings 24 hours after the timer is activated. This process is repeated cyclically every 24 hours. Stopping the timer stops this function.
Sold ONLY with our acoustic booths.
