Airflow QT100HT 4 Inch Quiet Air Bathroom Fan with Humidistat and Timer - 9041261

Overview

The QT100HT is a mains voltage, very powerful and extremely quiet extractor fan that may be installed in all bathroom zones without a transformer. Using only 9w on full power, it is energy efficient but still boasts one of the highest extraction rates in any four inch axial fan, of 90m3/hr.

The integral humidistat operates the fan automatically according to the relative humidity of the bathroom - adjustable upon install from 65% - 90% RH. The timer is adjustable from 6 - 21 minutes. The QT100HT may be ducted up to 10m and round 90 degree bends without power loss. The QT100HT also features an intelligent delay start for night time trips to the bathroom.
