450-1550m3/H Airflow Marine Axial Fan Corrosion Resistant Low Noise

CWZ Series Marine Axial Fan with 450-1550 m³/h Airflow, Corrosion Resistant and Low Noise for Navy Ventilation

1,General

CWZ series marine small sized axial fans are suitable for ventilation of kitchen, lavatory, bulkhead, the public place and meeting room etc on the naval and merchant ships. They are also applicable for other suitable places.

2,Features

The fans are designed according to arbitrary vortex flow method. We choose the most reasonable vortex flow coefficient based on the fans specification, distribute every sectional characteristic sped & length of the blades. The fans have low noise, small size, Light weight and stable performance etc.

During the design & manufacture, 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, safety and reliability.

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)

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

Type ll-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.

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