The plastic centrifugal fan impeller has the characteristics of high strength, light weight, good corrosion resistance, aging resistance and low noise. It is an ideal new anti-corrosion fan, suitable for chemical, textile, electroplating, laboratory and other places. A certain concentration of corrosive gases such as acids, bases, and salts.
The plastic centrifugal fan impeller can also be used as a ventilation and ventilation for buildings in general factories. It is not allowed to exclude corrosive gases such as halogen derivatives and ketones containing aromatic compounds, aliphatic and aromatic hydrocarbons. The fan is used at a temperature of 0 to 40 degrees and is protected from the sun. There is no heat source near the site.
The plastic centrifugal fan impeller, blade and air inlet are all made of glass fiber and strong polypropylene tube. The production process of mold injection molding greatly improves the mechanical strength of the impeller. At the same time, the auxiliary impeller is added to the rear disc of the plastic centrifugal fan impeller, so that the gap between the shaft diameter and the center hole of the casing during the operation of the fan creates a negative pressure zone, and the toxic and harmful corrosive gas is not leaked during the operation.
