Fan (Blower)

FAN(BLOWER)

The number of decimeters of the diameter of the fan impeller is the machine number of the fan. It is expressed in Arabic numerals, and the letters after the 

machine number indicate the transmission mode of the fan. www.immyhitech.com 

 The transmission methods commonly used are:

1. "C" type - one indicates the fan cantilever, and the belt pulley is transmitted on the outside of the bearing.

"D" type - indicates the fan cantilever, with support and coupling transmission.

2. The rotation direction of the fan is divided into two types: left and right rotation. The distinguishing method is to look at the impeller from the direction of transmission. When the fan is working, the clockwise rotation of the impeller is right rotation, and vice is left rotation.

3. The direction of the air outlet of the fan is generally made of 90 degrees. If the user has special requirements, it can be indicated on the order.
