Mechanical constant ﬂow dampers external casing is made from galvanized sheet metal and the blades are manufactured from aluminium.
This is a mechanical constant ﬂow damper used to regulate the air pressure in suction and extraction lines. Due to its spring mechanism that works in accordance with the pressure in the duct, it does not require a motor or an electrical connection and provides the required air pressure. It works between a pressure range of 50 pa minimum and 100 pa maximum air pressure, the recommended operational air ﬂow rate is between 2-10 metres per second.
