Backward Curved Blades Centrifugal Fan

 

1. Application:

4-72 centrifugal ventilators are suitable for Petroleum, Chemical industry, metallurgy, Electroplating, Sewage treatment, Brewing, Textiles, Electronics and other area. This fans are used for ventilation and air-change.

 

2.Advantage.

This ventilator has the features such as:high efficiency, low noise, stable pressure curve and anti-corrosion and energy saving, convenient installation, wide application.

 

3. Model

This kind of centrifugal fan are divided in to ACD three connect way, type A means the motor connect with the impeller directly, the C type means the motor and the impeller connected by the belt, type D means connected by the coupler.

 

4.Material

The fans can be made of FRP material, steel material, stainless steel material, aluminum material, PP/PVC material.

 

5.Structure:

Centrifugal fan consists of motor, cabinet, principal axis, impeller, bears, transmission mechanism, support frame etc.

Besides of centrifugal fans with low pressure, medium pressure, and high pressure, we also produce customs-made products to get the beat match between economy and performance.

Features

1.Applying optimizing design method, modular design, quality process control, and customs-made etc. different way to meet the different needs of the customs.

The Max. Efficiency can be 90%, which is 5% higher than the competitors.

Wide range of technical parameter ensures the fans run at its best efficiency at the specified applications.
