The Select AX100HT is a basic single speed axial fan with anti-backdraught shutters and built in guide vanes to improve airflow. The fan has an on/off pull cord switch. Switching off will activate the overrun Timer
These carry on running for an adjustable period - usually about twenty minutes after it has been switched off - but this can be set to anywhere between two and thirty minutes. The benefit is that the fan will continue to operate when the room is no longer in use, continuing to clear the moisture.timer. The fan will switch off at the end of the overrun time which can be altered by adjusting the sensor.
Humidstat fans have a sensor in them. This detects moisture in the air. When a set humidity point is reached the fan will switch on. There are two types of sensor – Traditional and Digital/Intelligent.
Traditional. Work by having a fixed humidity level which, when reached, the fan activates. Traditional humidistats work well but as natural levels of humidity rise and fall between summer and winter, they can become more or less sensitive to switch on periodically.
Digital/Intelligent. Have no fixed humidity point for activation. Instead they constantly measure humidity levels and only activate when man-made spikes in humidity - caused by showering, bathing or cooking - are detected. Consequently they are more responsive to run only when required
The IP rated 24 fan can be located in Zones 1, 2 or Outside.
