DRAUGHT MODULATOR

This regulator is installed in a chimney flue with the aim to adjust the internal flow of the chimney and to obtain the best performance from the appliance. It is equipped with a control valve with its counterweight. The counterweight adjusts and maintains pressure ratio. Anytime that chimney draught results too high, the control valve opens itself and let the air enter, to reduce draught until the desired level.

The installation of draft modulator in rooms without natural ventilation is forbidden. Draft modulator works perfectly only if positioned in perfectly horizontal position.

Available only diameter 150 male, it could be used through tees with female horizontal exit diam. 150 or suitable reductions.
