The Fantech QuietflowDCV inline fan range is a new concept that uses sensors to automatically control the amount of ventilation according to the occupancy of a room.

Demand Control Ventilation (DCV) increases the efficiency and effectiveness of the ventilation system and reduces energy consumption.

The Quietflow DVC inline fan is described as lightweight ventilation system with a galvanised sheet steel casing. It is lined with flame retardant Class O rated acoustic lining which ensures breakout noise is low. To achieve this, the DCV system is available with a series of on-board different sensors which continuously monitor the conditions in the room and feed the information back to the on board DCV zone controller in real time.

The controller then adjusts the Quietflow fan speed modulating the ventilation rate to suit the environmental conditions and occupancy levels of the room.
