    Functional description The Condair RM steam humidifier is an atmospheric steam humidifier. It operates on the resistance heating principle and is designed for indirect humidification via a steam distributor in venti lating and air-conditioning systems. Water supply The water is supplied via a filter valve (accessory "Z261") to the steam humidifier. It reaches the steam tank via the level controlled inlet valve and the open filling cup.
