4-79/4-2*79 Centrifugal Fan
4-79 Centrifugal Fan is mainly used in general factories and large-scale buildings for indoor ventilation, air inhaling and exhaling. The gas should be no more than 80℃, non-pyrophoric, non-harmful for human body and non-corrosion for steels. The gas shall not contain adhesive matter or dust and hard particle contents greater than 150mg/m3.

Key Advantages:
Impellers- They consist of 16 backward arc-shape round-plate blades, curved front plates and plate-shape back plates. They are made of steel plates and pass dynamic balancing correction. They enjoy good aerodynamic performance, high efficiency, low noise, balanced operation.
1. Air inlet -Being installed at one side of the blower in an integrated structure, it is in curved shape with the horizontally parallel section and enables air to flow into the impeller easily with little loss.
2. Driving system -It is composed of main shaft, bearing box, rolling bearing, belt pulley or coupling.
