The manual rectangular duct damper is made of PP polypropylene, which is resistant to acid and alkali corrosion. The production process of the manual rectangular duct damper is relatively complicated. It needs to be carved and cut from polypropylene PP sheet, and then produced by company A by manual welding. Production cannot be automated, so the cost of the rectangular duct damper is high.
Manual rectangular duct damper is suitable for chemical plants, laboratories and other application environments with explosion-proof requirements. It is used in PP material ventilation duct systems and is connected with PP air ducts. It is used for corrosive gas extraction and exhaust control, anti-corrosion, acid and alkali resistance , PP plastic manual rectangular duct damper complete specifications, supporting PP duct, elbow, tee, variable diameter use, constitute a complete PP ventilation duct system.
