Dkf single intake motor direct coupled backward inclined wing centrifugal fan

　　1. Fan model description:

　　2. The common installation and transmission forms of fans are shown in the figure below:

3. The product adopts high-quality steel plate plastic spraying, parts forming and molding, general assembly line operation, and the main parts adopt advanced processes such as impeller welding, volute undercut, tox riveting and so on.

4. The impeller is a backward inclined air core machine wing impeller with high efficiency, low noise, large flow and high pressure. The product has the characteristics of reasonable structure, long service life, wide use, safe and reliable use, convenient and fast adjustment, etc.

5. Dkf series fan is of single air inlet structure (only one air inlet), equipped with special connecting flange, which can be directly connected with the air inlet pipe to save installation space.

6. The performance of the sample fan refers to the performance under the standard state. That is, atmospheric pressure PA = 101.325kpa, gas temperature T = 20 ℃, gas density ρ= 1.2kg/m3。 The performance parameters listed in the technical parameter table are parameters in the normal operation area of the fan (i.e. the red shaded part in the performance curve).

7. KF series fans can be made into explosion-proof fans with explosion-proof certificate and explosion-proof grade Exd Ⅱ BT4.

8. Please indicate the fan model, installation form, flow, total pressure, etc. If there are other special requirements, please specify.

9. Other installation forms and special purpose fans can be designed according to user requirements.
