3. Construction

1. The impeller is made of anticorrosive casting aluminum alloy, it is aerodynamically shaped and carefully balanced to ensure the fan having reliable anticorrosive property and operating smoothly.

2. The fan casing being wilding struction, is made of steel plate with flanges for connection with duct at both by bolts, and the surface is fully treated by anticorrosive painting.

3. As desired, the casing can be made into a solid type or a split one along the cotter pins of axial direction.

4. Taking a front view from the motor side, the impeller should be turning clockwise, in practice, it can be turning anti-clockwise too. Such being the case, the reversing characteristic are:

Capacity not less than 60 percent of normal rating.

5. AC.50HZ, 380V or 60HZ, 440V, type Y-H three-phase asynchronous motors for marine exclusive use may be used for these fans.
