They combine the automatic swinging airflow of conventional oscillating fans with explosion-proof safety features.
Their core purpose is to provide safe and efficient ventilation and cooling in areas where flammable gases, vapors, or dust are present.




Encrypted Mesh Design
The encrypted mesh protective cover effectively prevents foreign objects from entering and ensures personal safety. The unique quick-release screw design on the edge allows for easy installation and removal without complex tools, greatly simplifying daily
cleaning and maintenance. While providing strong protection, it also balances ease of use with safety and reliability.
High-Strength Aluminum Alloy Blades
The fan blades are crafted from aircraft-grade, high-strength aluminum alloy and are precisely dynamically balanced. This not only
ensures high airflow and efficiency, but also significantly reduces noise and vibration during operation, delivering a quiet and
stable operation experience and extending the lifespan of the device.




Aluminum Alloy Die-Cast Body
The housing is constructed from a one-piece die-cast aluminum alloy, offering a sturdy structure and excellent heat dissipation.
This product is rigorously certified to Ex d IIB T4 Gb explosion-proof rating and features flexible speed adjustment, making it
safe for use in Zone 1 and Zone 2 hazardous areas with Class IIA and IIB explosive atmospheres. It supports stepless or variable
speed regulation, allowing precise control of airflow based on actual needs.
Four-Corner Reinforced Support Structure
The unique four-corner reinforced support bracket design features a scientifically designed structure, rock-solid operation, and
extremely high installation stability and vibration resistance. This design effectively absorbs various stresses during operation,
ensuring the fan remains stable and quiet even at high speeds, eliminating safety hazards caused by shaking.




Core Pure Copper Motor
The core pure copper motor provides wide-range explosion-proof compatibility. The power core utilizes a high-efficiency pure
copper coil motor, characterized by low temperature rise, long life, and strong power. Its excellent explosion-proof performance
makes it widely suitable for hazardous locations with Class IIA and IIB explosive gases, such as petroleum refining, chemical
production, manufacturing, pharmaceutical processing, gas stations, and hazardous materials warehouses, making it a reliable
choice for ensuring safe production.
