Marine Ventilation Fan

CBZ-I Marine Explosion-Proof Axial Ventilation Fan for Deck Installation

The CBZ-I Marine Explosion-Proof Axial Ventilation Fan is a robust and reliable solution designed specifically for deck installation on marine vessels. This explosion-proof fan adheres to stringent standards including GB11800-89 (marine explosion-proof axial flow fan), GB3836-83 (electrical apparatus for explosive atmospheres, with a “d” type explosion-proof electrical equipment rating), and regulations for the construction and classification of sea-going steel ships. It ensures safe and efficient ventilation in hazardous environments.

Applications:

This versatile explosion-proof fan is engineered to handle the transportation of gas mixtures or vapors containing combustibles and explosives, ordinary air, sea air laden with salt fog, oil-laden air, and other corrosive air supplies or extractions. It is ideally suited for:

• Oil tanks
• Cargo tanks
• Pump rooms
• Battery compartments
• Ammunition storage areas
• Hangars
• Paint houses
• Other ship compartments and corresponding land-based locations

The fan can be equipped with either an AC 50Hz, 380V or 60Hz, 440V marine three-phase asynchronous motor, ensuring compatibility with various power systems.

Structural Types:

1. Type I – Deck Type: Features a hood and an explosion-proof motor mounted on top of the machine frame, with a wide mesh cover (2 mesh/sq in). The fan is vertically fixed on the deck and can be used for both pumping and sending air.
2. Type II – Duct Type: Lacks a hood and incorporates a built-in explosion-proof motor mounted on the housing by downstream guide vanes. It can be installed vertically or horizontally and is also suitable for deck installation.
3. Types III, IV, V – Custom Configurations: Based on customer requirements, these types feature the fan and motor in separate compartments, connected via a driving device, sealed box, and flexible couplings. They are primarily used for exhausting dangerous compartments. Type III can be installed horizontally, while Types IV and V can be vertically fixed on the deck.
