CWZ-250D Marine Small-sized Axial Blower

1. General
CWZ-250D marine small-sized axial blowers are suitable for ventilation of kitchen, lavatory, bulkhead, the public place and meeting room etc. in the naval and merchant ships. They are also applicable in other places that suit.

2. Features
CWZ-250D marine small-sized axial blowers are designed according to arbitrary vortex flow method. We choose the most reasonable vortex flow coefficient or the basis of the fans, specification, distribute every sectional characteristic speed &l length of the vanes, the fans have low-noise, small size, light-weight, stable performance, etc.
In the course of designing & manufacturing, we have 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, stable running and safety reliable.
CWZ-250D marine small-sized axial blowers can be used with 380V/220V. 50Hz or 440V/220V, 60Hz motors.

3. Structure
CWZ-250D marine small-sized axial blowers can be made into two structure types, type I (tube type), type II (porthole type):
Type I -tube type for ventilation of short tubes or fixed on the bulkhead.
Type II -fixed on porthole. It can be fixed on the porthole or the bulkhead. Since it’s water-proof it can be easily opened or closed to keep rain or sea water out.
CWZ-250D marine small-sized axial blowers Impeller is made of cast aluminum alloy; casing is welded by steel sheet.
