Air damper means the valve or a plate which can prevent or adjust/regulate air flow volume in the pipe or ventilation duct, chimney pipe, VAV box device, air handling machine, or other air processing equipments. This Plastic Butterfly Duct Damper valve is manufactured for suiting for flowing all corrosive and non-corrosive gas environments, high and low temperature service as well.Plastic Butterfly Duct Damper valve provides long-lasting, cost-effective solutions for industrial and institutional corrosive fume exhaust and drain applications.

• PP air damper is non-toxic, anti-corrosion,health, stand high temperature;
• Anti-rust: PP air damper can withstand PH value in a wide range of temperatures, high concentrations in the range of 1 to 14 acid and alkali corrosion;
• Wear-resistant, non-fouling: PP air damper has uniform and smooth tube inner wall small,small flow resistance and no scaling;
• Reducing vibration and noise: PP air damper has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
•  anti-cracking: PP material is good elasticity,which makes pipes and fittings sectionally together with the expansion of the liquid frost without bursting.
•  anti-condensation, less heat loss: PP material is a poor thermal conductor, reducing condensation and reduce heat loss.
• Easy Installation: PP damper valve is light weight, easy to install and operate, meltable and has weldability.
• Long service life: PP duct damper valve systems can serve 50 years.
