CWZ series marine or navy small-sized axial fans are suitable for many appropriate places like kitchen and etc. for ventilation.

CWZ series marine or navy small-sized axial fans are suitable for the ventilation of kitchen, bulkhead, the public places, the meeting room, in the naval merchant shops and so on. They are also applicable in the other places that suit.

The fans can be made into two structure types, type(tube type),type(porthole type):

type-tube for ventilation of short tubes or fixed on the bulkhead.

type fixed on porthole. It can be fixed on the porthole or the bulkhead. Since its water-proof it can be easily opened or closed, to keep rain or sea water out.

Impeller is made of cast aluminum alloy, casing is welded of steel sheet.

Features:

The fans are designed according to arbitary vortes flow method. We choose the most reasonable vortes flow coefficient on the vanes of the fans and distribute every sectional characteristic speed & length of the vanes. The fans have low-noise, small size, light-weight, stable performance, etc.

In the course of designing & manufacturing, we had thought fully of the marine special conditions, the impellers are strictly made by dynamic balance adjustment & over speed test. Therefore, the fans also have the features of good-anticorrosion, anti-swing, vibration resistance, shock resistance, stable running and safety reliable.

The fans can be used with 380V/220V, 50Hz or 440V/220V, 60Hz.

Precaution:

1. The hard particulate matter in the combustible and explosive gas mixture is not allowed to be more than 150mg/m3, and its maximum diameter cannot exceed to 2mm.

2. On the duct intake side, providing a protective brass wire nets to ensure the prevention of foreign matter and electrostatic sparks from invasion, so as to insure the explosion-proof fan operating safely.

3. When a power cable is inserted in the terminal box and fixed there, the terminal box itself and its approaching device must be sealed tightly with the cable, and no permeation of rain water into the terminal box is allowable.

4. Be sure to earth the cable, especially the flameproof motor.

5. Explosion-proof fan installation should be carried out with much care in connecting with the duct so as not to allow any casing distortion to take place owing to forceful tightening. Furthermore, it is not allowed to add the weight of pipes to fans by force.

6. The motor power wired by fans refers to mechanical losses and its own safe coefficient under given working conditions. Be sure to adjust the air rate and strictly control motors electrical current. It is forbidden to exceed motors electrical current rating.

7. The cable entry thread of the flam-proof motors are shown in table:

8. Our products can be exchanged, returned and repaired if you found its quality unsatisfactory within 18 months from the date of ex-factory.
