Marine Low Noise Axial Fan

1General
CZT series marine low noise axial fans (the fans) are new type and energy save and low noise products. They have the features of high efficiency, low noise, no overload, stable running and meeting the marine conditions etc. They are suitable for chamber ventilation and also applicable for other suitable places.
2. features
　During the course of design and manufacture, we had thought fully of the marine secial condition, the impellers are strictly done dynamic balance and over speed test. Therefore, the fans also have the features of good corrosion, swing resistance, shock resistance and vibration resistance, stable turning, safety and reliability etc.
3.Structure
The impellers are anti corrosive aluminium alloy. The housing and support are made of common steel sheet and taken anti corrosive measures.
Looking directly from the motor side,the impeller turn clockwise, it can also reverse.
