The full name of Electric volume control damper is Duct Volume Control Damper, which is used to adjust the air volume in the exhaust gas treatment and exhaust pipeline, and is resistant to acid and alkali. The diameter below 315 is a one-time forming duct damper, and the diameter above 315 is made by manual processing. The PP duct damper is an accessory of the PP duct damper, which is indispensable in the exhaust engineering. Different, the air volume changes, each tuyere cannot guarantee the same air volume, so the PP air duct is installed with the tuyere to adjust the cross-sectional area of the tuyere and maintain a constant wind speed and air volume. The installation of PP duct damper linkage pressure controller and fan frequency converter in the exhaust system can control the air volume, reduce the frequency of the fan, and save energy and protect the environment.

In addition, in order to form a complete anti-corrosion pipeline system, in addition to PP straight pipes, it is not enough to have the following PP air duct accessories, which can be combined with the installation to form a complete anti-corrosion acid and alkali-resistant exhaust air pipeline system.

PP elbow

PP tee

PP reducer

PP flange

PP casing

PP duct damper

We collectively refer to the above products as PP air duct system
