Chimney Draught Regulator- effective draught stabilisation in chimney ducts

Chimney Draught Regulator is a device that efficiently reduces and stabilises excess underpressure in chimneys. It works both in case of chimneys that are sized correctly, as well as those, in which the cross-section of the chimney is too high. It will prove itself perfectly in conditions, in which excess draught is caused by variable weather conditions – e. g. strong wind. The damper in draught regulator is designed in such a way that excess underpressure, exceeding the value set on the adjustment knob, would cause the damper to open, thereby providing additional air to the chimney. This will cause a reduction of the underpressure value in the chimney chamber, on the one hand – through cooling of the exhaust fumes, on the other – by increasing flow resistance – as the chimney, beside the exhaust, must also transport air.
