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 a 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.

The manual rectangular duct damper is a kind of non-sealed butterfly valve, which is widely used in universities, chemical, biological, electric power, energy, environmental engineering, etc. in the production process, the medium temperature is less than or equal to 90ºC, and the nominal pressure is less than 0.1Mpa. It is usually installed on the top of the fume hood, the PP suction hood, and the inlet of the pipeline of the one-use-one-standby spray tower to switch the exhaust gas flow direction of the spray tower.

Product characteristics:

PP material processing, acid, and alkali corrosion resistance, strong anti-corrosion performance;

PP square duct damper is designed with sockets at both ends, and a flange connection can also be welded;

High-strength actuator, all-copper design, switch life more than 20,000 times;

The inner and outer walls are smooth and the wind resistance is small.
