CDZ Marine Low Noise Axial Fan:

General:

CDZ Series marine low-noise axial fans is new-type & enery-save, low-noise marine product. It has the features of high-efficiency, low-noise, stable-turning,meeting the marine conditions, etc. They are suitable for air ventilating and exchanging in every cabin on ships. They are also applicable in other places that suit.

 

Features:

The fan is designed according to arbitrary vortex flow method.We choose the most reasonable vortex flow coefficient on the basis of the fan specification,distribute every sectional characteristic speed&length of the vanes,make full use of the high peripheral velocity of the vane point.Therefore,they have the features of high- efficiency, low- noise, large-flow&pressure coefficient,light-weight,etc.

In the course of designing & manufacturing, we have thought fully of the marine special conditions, the impellers are strictly made by dynamic balance adjustment & over speed test. Therefore, the fan also has the features of good-corrosive resistance, resistance to swing, resistance to shock and vibration, stable turning, safety & reliability, etc.

 

Structure:

The impeller is riveted by vane which is pressed by aluminium sheet die set and hub boss which is steel-galvanized. The casing and support art made of common steel and they are treated in corrosion resistance.
Look directly from the motor side, the impeller turn counter clockwise.
Because that the fan’s vane are made of aluminium sheet, it suits for using in the conditions of low-pressure, large-flow.

The fan can allocate with the marine AC motor.
