The DC axial fan with protective metal grill is a safety-enhanced heat dissipation fan specially designed for equipment scenarios with high requirements for operation safety and anti-collision protection. Ordinary open cooling fans have exposed blades, which are easy to contact with external sundries, wires and even human hands during operation, resulting in blade collision damage, fan stuck failure, and even personal scratch injury and equipment short circuit accidents. Especially in open industrial production sites, public electronic equipment and frequently operated mechanical equipment, the safety hazards of unprotected fans are prominent, and it is easy to cause equipment failure and safety accidents due to accidental contact and foreign object invasion.

This fan is equipped with a high-strength integrated metal protective grill on the basis of the standard DC axial fan body. The grill is made of high-quality steel wire through precision welding and anti-rust and anti-corrosion treatment, with firm structure, strong impact resistance and not easy to deform and damage. The uniform grid spacing design can effectively block external foreign objects such as sundries, tools and human body contact, completely avoid the risk of blade collision and personal injury during fan operation, and greatly improve the overall operation safety of the equipment. At the same time, the hollow grid structure is scientifically designed, which does not block the air flow, does not affect the original air volume and wind pressure performance of the fan, and ensures the efficient heat dissipation effect of the equipment.

The fan body adopts high-performance brushless DC motor, with stable operation, low noise, energy saving and high efficiency, and long service life. The metal grill is firmly connected with the fan frame, not easy to fall off, and has strong durability and environmental adaptability. It is widely used in industrial open equipment, medical electronic equipment, public charging equipment, automated production lines and other safety-sensitive application scenarios. It not only provides stable and efficient ventilation and heat dissipation functions for the equipment, but also builds a solid safety protection barrier, effectively avoiding safety accidents and equipment damage caused by external interference, and ensuring the safe and stable operation of the equipment and the personal safety of operators.
