40x40x20mm DC 24V Brushless Fan — Industrial High-Pressure Cooling 🌬️⚙️

This is a professional-grade DC brushless axial fan designed for high-efficiency thermal management in 24V industrial systems. This fan features a specialized 20mm depth, providing double the thickness of standard slim fans to generate superior static pressure. It is an ideal cooling solution for industrial 3D printers, server enclosures, and automation control panels where air must be pushed through dense internal components.

Engineered for long-term reliability, the sleeve bearing motor ensures consistent performance in demanding environments.

Key Performance Features

• High-Static Pressure 20mm Profile: The 40mm x 40mm x 20mm dimensions allow for larger fan blades that move air more effectively through restricted spaces compared to slim 10mm models.

• Industrial 24V Optimization: Specifically designed for DC 24V power rails, common in industrial machinery and high-end 3D printer motherboards.

• Reliable Sleeve Bearing Motor: Features a DC brushless design with a sleeve bearing for a balanced operation and reduced mechanical friction.

• Rapid Installation: Equipped with a pre-wired 2-pin terminal connector (Red/Black leads) for seamless, tool-free integration.

• Safety Certified: Fully carries the CE mark, ensuring the product meets international safety and quality standards.

Top 3 Customer Questions & Concerns 🙋‍♂️

🔄 How do I tell the airflow direction? Air typically exhausts through the side with the manufacturer’s label and the motor support struts. For optimal cooling, ensure the label side is facing the direction you want the heat to be moved.

🛡️ Is it safe to run this fan 24/7? Yes. The brushless motor design and CE certification signify that the fan is engineered for the continuous operation demands of professional electronics.

🔌 Can I use this fan with a 12V power supply? While the fan may spin at 12V, it will operate at a much lower speed and may not provide sufficient airflow or start reliably. To achieve rated performance, a 24V DC source is required.
