Draft Regulator is a thermostatic, chain-controlled combustion air regulator. This is designed to regulate solid fuel heat sources as coal-fired boilers and wood-fired boilers. Its metal construction and a composite head ensure good resistance against high temperatures and mechanical damage. The thermostatic element guarantees precise operation and long service life of the regulator. The regulator has a standard lever of 120 x 145 mm, 120° bend and its regulation range is 30-90 °C and max. chain load is 0.8 kg. It keeps the heating water temperature at the value set by means of a rotating knob. It can be easily installed to any boiler type either horizontally or vertically.
