The latest radar sensor technology built-in

The AUX Fan is equipped with the latest radar sensor technology. It recognizes movement and automatically starts the exhaust process when someone enters the room. After ~10 minutes, the fan is automatically stopped and the shutter closed to prevent backflow.

Conventional infrared type sensors need to be installed externally, but the AUX Fan's sensor is integrated. This keeps it simple, as there is no need for extra wiring to operate the sensor.

The AUX Fan adopted a radar type human sensor. Unlike a conventional infrared sensor, small pets and sunlight can no longer be mistaken for a person, preventing unnecessary ventilation operations.

The AUX Fan sends out a small amount of radar waves to determine the position of people in the room. It can detect that people remain in the room even if they stopped moving. The AUX Fan runs for ~10 minutes after detecting movement.

Upon leaving the bathroom, the AUX Fan recognizes that there is no longer a person inside and will exhaust air for up to 10 minutes.

The radar sensor runs on a very weak current with almost no power consumption.

Moreover, a power-saving DC type motor is used.

The AUX Fan provides optimal local ventilation, even in combination with a heat exchange ventilation system.
A heat exchange ventilation system ventilates air both in- and outwards simultaneously. The balance between inflow and outflow is highly important, because such a system absorbs heat when exhausting and returns this heat when ventilating inwards. Heat exchange ventilation is optimized to equalize in- and outflow to maintain a high heat exchange efficiency. If however a local ventilation fan, such as a toilet fan, sucks out air and operates in tandem with a heat exchange ventilation system, negative pressure will result in a decreased efficiency for the heat exchange ventilation system. That is how the AUX Fan was born.
