JCZ70A Ship engine room ventilation fan
JCZ(CZ)MARINE AXIAL FLOW FAN

1.MARINE FAN PREFACE

　　JCZ(CZ)series axial-flow marine fan for marine or navy use series fans are designed and manufactured according to the standards of the state for GB11865《Marine Centrifugal Ventilator》,GB11864《Marine Explosion-proof Axial Flow Fans》 《Rules and Regulations for the Construction and Classification of Sea-going Steel Ships》and《Rules and Regulations for the Construction of PLA Naval Ships》.

　　This series of marine fan ventilators have been examined and proved up to stand by the Register of Shipping of china and have got the certificate .They are also approved by the authority of shipping equipment and research Staff. 

2.MARINE FAN USES

　　JCZ marine fan ventilators can carry ordinary air, sea air containing salt fog and air containing oil fog and other corrosives.

　　These marine fan ventilators are suitable for ventilation of all kinds of tanks in the naval and merchant ships. The marine fan can also be used for partly cooling. They can be used on land, either.

        JCZ marine fan ventilators can be matched with Y-J three phase naval induction motor or Y-H three phase marine induction motor(50Hz,380V or 60Hz,440V)

3.MARINE FAN WORKING CONDITIONS

ambient temperature:-25~55℃

relative humidity of air:<=95%

cyclical oscillation: 22.5~45° (oscillation cycle 5~10s)

sustained horizontal tilting:15°

sustained vertical tilting:10°

vibration: existent 

shock: existent. 

4.JCZ type Marine Fan:

　　The marine fan ventilator is manufactured with a built-in casing motor structure. The vane wheel is directly mounted on the motor shaft. The blade is made of anticorrosive cast aluminum alloy while the casing is made of welded common steel .In front of the vane wheel there is an inducer. Viewed from the motor side, the vane wheel rotates clockwise while in service the marine fan ventilator is allowed to rotate reversely. The ventilator can be installed vertically or horizontally and can also be installed on the deck or in the pipe. It may be used for pumping or inducing air. According to the user's need, we can supply hood together with JCZ type marine fan ventilator. 

5.MARINE FAN MODELS

　The models of marine fan ventilators are expressed by the first letter of the Chinese phonetic name, the outer diameter of the vane wheel, the power and the rotational speed of the motor ,etc.
