Marine Centrifugal Fans

CQ Marine Centrifugal Fans for Marine Ventilation Systems

The CQ series marine centrifugal fans are a robust and reliable solution designed specifically for the demanding marine environment. This fan is engineered to effectively circulate and ventilate air, including ocean air laden with salt vapor, corrosive air containing oil vapor, and small quantities of acid steam generated by the natural evaporation of batteries. Its versatility makes it an ideal choice for ventilation in various cabin rooms, boiler rooms, and other suitable areas onboard marine vessels.

Compliance and Standards:
Our CQ marine centrifugal fans are meticulously designed and manufactured in accordance with the stringent standards of GB11865 “Marine Centrifugal Fan” and “The Manufacture Rules of Sea-going Steel Ships,” which have been approved by the Register of the People’s Republic of China. This ensures that our fans meet the highest quality and safety requirements for marine applications.

Key Features and Benefits:

• Compact and Lightweight Design: The CQ marine centrifugal fan is designed to be small in size and light in weight, making it easy to install and integrate into existing marine ventilation systems.
• Low Noise and Vibration: With advanced engineering, our fans operate with minimal noise and vibration, providing a comfortable and quiet environment onboard.
• Excellent Anti-Corrosiveness: The fan’s materials and coatings are selected for their superior resistance to corrosion, ensuring long-lasting performance even in harsh marine conditions.
• Superior Air Tightness: The fan’s casing and air inlet are designed to prevent air leakage, maintaining efficient ventilation and reducing energy consumption.
• Low Starting Torque: The fan requires minimal starting torque, making it easy to start and operate, even in low-voltage conditions.
• Strong Resistance to Swing, Vibration, and Shock: The fan is built to withstand the rigors of marine operations, including swinging, vibration, and shock, ensuring reliable performance in all conditions.

Structure Type:
The CQ marine centrifugal fans are available in both horizontal and vertical structure types to suit different installation requirements. The impellers are directly riveted onto the motor shaft extension, ensuring efficient power transmission. Made of high-quality aluminum alloy, the impellers are carefully balanced both statically and dynamically to minimize vibration and noise. The casing and air inlet are constructed from welded common steel, providing durability and strength.

Rotation Direction and Motor Options:
The fan can be customized for either anticlockwise (turn left) or clockwise (turn right) rotation to meet specific installation needs. It can be matched with a marine AC motor (380V/50Hz) or a marine DC motor (220V), offering flexibility in power supply options.
