CWZ-224D marine small-sized axial draft fan

1.General

CWZ-224D marine small-sized axial draft fans are suitable for, ventilation of kitchen ,lavatory, bulkhead ,the public places ,the meeting room etc, in the naval and merchant shops. They are also applicable in other places that suit.

2.Features

The fans are designed according to arbiter votes flow method. We choose the most reasonable votes flow coefficient on the vanes of the fans, specification ,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.

3.Structure

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

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