Overview

The Airflow iCONstant is a revolutionary dMEV (Decentralised Mechanical Extract Ventilation) unit which can operate as both a continuous running fan on a low 'trickle' setting and an intermittent fan via a 'boost' setting.

The 4"/100mm fan is IPX5 rated and may therefore be installed anywhere in Zones 1 and 2 of the bathroom, in either the wall or ceiling and can be ducted up to 4m in a straight line. The 72687118 / ICSTHT model features an over run timer which keeps the boost setting running for 2 / 15 / 30 / 40 minutes and a humidistat. The humidity sensor is adjustable between 60% and 90% relative humidity and will turn the fan on when moisture in the bathroom reaches this pre-set level.
