30~120 ": diameter of impeller

Composition: Mainly composed of shell, motor, transmission group, impeller, guide cover, explosion-proof copper ring, etc.

Basic parameters:

● Airflow: 500-10000m3/h

● Total pressure: 100-705Pa

Power: 0.55kW~370kW

● Electrical system: Standard configuration AC 3PH 380V/50Hz, AC 3PH 440V/60Hz， If necessary, other electrical systems can be selected: AC 3PH 415V/50Hz，AC 3PH 460V/60Hz，AC 3PH 480V/60Hz，AC 3PH 690V/60Hz。

● Shell: The structural type is cylindrical, mainly used to collect gas, guide the gas, and improve the internal efficiency of the fan. The ventilation fan shell can be made as a whole or opened along the axis according to needs. Open type casing refers to the installation of impellers and motors on an openable half casing, which facilitates on-site maintenance and replacement of components.

● Impeller: The structural type is wing shaped blades, made of ZL104 cast aluminum alloy, and has undergone strict dynamic balance correction and overspeed testing.

● Marine electric motor: It has good moisture resistance, mold resistance, and salt spray resistance, and is characterized by smooth operation and low noise. The windings and metal parts of marine electric motors are specially impregnated and treated according to the requirements of wet tropical motors, and have good moisture resistance, mold resistance, and salt spray resistance. The surface of the base of marine electric motors has axial heat dissipation ribs, which can increase the cooling effect.

   Marine electric motors can be equipped with space heaters as required.

   Marine electric motors can be selected from domestic brands such as Texas Hengli, Jiangsu Dazhong, and Far East according to requirements, as well as imported brands such as ABB, Siemens, and BAIC.

Application scenarios:

Widely used in various types of oil tankers, container ships, and other ship types.
