1overview

The main features of DZ type axial flow fan are wide blades with large chord length, spatial distortion, and inclined blade shape, which can achieve the required air volume and pressure at low speeds and reduce fan noise. The diameter of the fan impeller varies from small to large, with a total of 34 specifications. Each specification has 4 blades, with an air volume of 400-48000M3/H and a wind pressure of 40-200PA. The fan can be wall mounted or pipe mounted.

2、 Product classification
1. Divided by external structure: wall type (DZ-11 type); Position type (DZ-12 type); Pipeline type (DZ-13 type)
2. Classified by usage environment:
A. Ordinary type: suitable for environments with non flammable, explosive, and non corrosive gases
B. Anti corrosion type: The impeller and casing are made of fiberglass, suitable for environments containing corrosive gases
C. Explosion proof type: The motor is explosion-proof and the blades are made of aluminum alloy, suitable for environments with flammable and explosive gases. The explosion-proof level is EXdllBT4
3. To meet the noise requirements of different places, the fan can be equipped with mufflers of different lengths, or it can be made into a wrapped type.

4、 Processing technology of DZ type axial flow fan
Fan impeller: The cross is made of steel stamped and formed by hydraulic pressure, and the blades are made of aluminum alloy stamped and formed by hydraulic pressure. The blades are assembled and formed by riveting with the cross. The impeller has undergone static and dynamic balance correction, and the balance accuracy is not greater than G5.6 level.
The outer flange is made by integral flanging and spinning
