  1. Explanation of ventilator model:

 

 

  2. The common drive and installation forms of the ventilator like chart show:

 

3.The ventilator should working in the gas environment, which the air does not contain large amount of caustic gas; it does not contain the acidic gas, the alkalinity gas, and the ignitable gas; the dust particle matter is not bigger than under 150mg/m3.

4.The product is made of quality steel plates, then electrostatic spray coat Also it can be made of quality galvanized steel plates. Spare parts are dieformed. The final assembly is done on assembly line. Main pars are produced by advanced crafts, such as rolling pressing impeller, undercutting shell, TOX riveting and etc.

5. The ventilator is with the FC multi-blade impeller, it is low noise, small volume, structure reasonable, long service life, broad use, multi-speed and so on the good characteristics; used safely and reliably.

6. The DF series ventilator is, and the drive is V-belt transmission. The standard high quality bearings are used in the product, enhances the nonbreakdown running time.
