Product description

GENERAL
Type GD30K2-12(T30I)axial fan is modified and designed based on Type FBZ-11 axial fan. Type CZL-11 axial fan with prolate axis can be replaced by it. It is specially handled the moist gas which is harmful to motor and also connected in pipelines. It is used to handle various harmful gases for chemical industry, papermaking, zinc plating and chicken farm units etc. Temperature should not exceed 60℃.
Type GD30K2-12 axial fan can be divided according to the impeller diameter: There are five models for №6、7、8、9、10。It has 4 blades and six blades. The installation angle: 15°、20°、25°、30°, there are 4 installation angles.


The characteristics of the fan is:
The motor is installed on the top of the duct and driven by triangle belt. The motor is supported by adjustable base plate of motor. The center distance is suitably adjusted. The driving unit is fixed in the seals of duct center and separated from medium. Thus the fan can deliver the moist and other harmful gases to the motor. The flow rate and pressure of the fan can be changed by changing revolutions.
The fan is welded by general steel. If the fan delivers corrosive, inflammable, explosive and volatile gases, indicate it when purchasing in order to consider it separately.

 

SELECTION
The performance of the fan normally indicates the performance under the standard state. The so called standard state indicates:

Where:
Q0、P0、N0、n0、ρ0 — indicates flow rate, pressure, power, speed and air density under the standard state.
Q、P、 N、 n  、ρ  — indicates the flow rate, pressure, power, speed and air density under the operation condition.
