Product Overview:
Features The damper frame and blades are stamped from galvanized steel, without welding, which makes the valve body more refractory and fire resistant. The bearing material is brass and can withstand high temperatures of 300°C;The use of parallel blades, optional actuators with adjustable air volume can be selected according to needs;Side sealing technology is adopted to ensure low air leakage.
