Details

CDZ-70-4  marine low-noise Axial Flow Ventilator

1.General 
CDZ-70-4 marine low-noise axial flow ventilators (simply the fans) is new-type & enery-save, low-noise marine products .They have the features of high-efficiency, low-noise, stable-turning,meeting the marine conditions, etc. They are suitable for every cabin air ventilating and exchanging on ships. They are slao applicable in other places that suit. 

2.Features
CDZ-70-4 marine low-noise axial flow ventilators are designed according to arbitrary vortex flow method.We choose the most reasonable vortex flow coefficient on the basis of the fans,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,ect.
In the course of designing & manufacturing, we hade thought fully of the marine special conditions, they impellers are strictly made by dynamic balance adjustment & over speed test. Therefore, the fans also have the features of good-corrosive resistance, resistance to swing, resistance to shock and vibration, stable turning, safety & reliability, ets.

3.Structure
CDZ-70-4 marine low-noise axial ventilators impeller is riveted by vane which is pressed by aluminium sheet die set and hub boss which is steel-galvanized. 
CDZ-70-4 marine low-noise axial ventilators 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.
CDZ-70-4 marine low-noise axial ventilators can allocate with the marine AC motor.
