I. Overview 

CQ series marine centrifugal ventilators (hereinafter referred to as ventilators) can transport air, marine air containing salt mist and corrosive air containing oil mist, etc. The ventilators are suitable for the ventilation of various compartments on ships, boiler ventilation, and can also be applied to other appropriate occasions.

CQ series marine centrifugal ventilators are designed and manufactured in accordance with the national standard GB/T11865 ‘Marine Centrifugal Ventilators’ and the current ‘Code of Practice for the Construction of Steel Sea-going Ships.

II. Characteristics

CQ series marine centrifugal ventilators are small in size, light in weight, low in noise, good in corrosion resistance, good in airtightness, small in starting torque, and strong in resistance to swaying, vibration and impact.

III. Structure 

CQ series marine centrifugal ventilator is horizontal, motor direct connection structure, can also be made into vertical structure. 
The impeller of CQ series marine centrifugal ventilator is made of aluminium alloy material riveted and corrected by static and dynamic balance.
CQ series marine centrifugal ventilator shell, air inlet, etc. are made of ordinary steel materials welded together and made into airtight structure.
CQ series marine centrifugal ventilator fan can be made into clockwise rotation (right turn) or counterclockwise rotation (left turn).
Reversal (left turn) a motor from the end of the front view, the impeller rotates in the counterclockwise direction, to ‘L’ said.
Clockwise rotation (right rotation) - When viewed from the motor side, the impeller rotates in the clockwise direction, and is indicated by ‘R’.
