CDZ series marine of low noise Axial Flow Fans

1. General

CDZ Series marine low-noise axial fans (simply the fans) are new-type & emery-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 slap applicable in other places that suit.

2. Features

The fans 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, and 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 oefficient, light-weight, etc.

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, est.

3. Structure

The impeller is riveted by vane which is pressed by aluminum 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 aluminum sheet, it suits for using in the conditions of low-pressure, large-flow.

The fans can allocate with the marine AC motor.
