24V 4020 Dc 3D Printer Vortex Turbo Cooling Fan

24V 4020 DC 3D Printer Vortex Turbo Cooling Fan is a powerful and compact centrifugal blower specifically engineered to meet the demanding thermal management needs of modern 3D printers and CNC equipment. This “turbo” or “blower” style fan creates high static pressure, making it exceptionally efficient at forcing air through restrictive channels, such as a hot-end heat break or a part-cooling duct. Operating directly on the standard 24V supply found in many 3D printers, consequently, this fan seamlessly integrates into systems like Creality, Ender, and other popular platforms. We recommend this 4020 radial fan when you need focused, high-velocity airflow to rapidly cool filament extrusions or prevent heat creep, ensuring consistent print quality and extending the lifespan of critical components. Furthermore, its brushless DC motor design ensures quiet operation and long-term reliability.

Key Features:

• High Static Pressure: The centrifugal (blower) design generates high pressure, effectively pushing air through restrictive ducts and cooling zones, which is critical for 3D printer hotends and part cooling.
• 24V DC Operation: This fan utilizes the industry-standard 24V power supply, therefore, it simplifies wiring and ensures compatibility with most modern 3D printing control boards.
• Compact 4020 Size: With dimensions of 40x40x20mm, the fan offers a superior performance profile compared to thinner 4010 fans, yet it maintains a small footprint suitable for constrained spaces.
• Brushless Motor: Incorporating a reliable brushless DC motor, the fan guarantees stable high-speed rotation, long service life, and minimal operational noise.
• Durable Construction: Manufacturers typically construct the housing from PBT (Polybutylene Terephthalate) plastic, a material that offers excellent resistance to high temperatures and general wear.

Commonly Used in:

• 3D Printer Extruder Cooling: Ideal for providing airflow to cool the heat break zone and prevent heat creep into the cold end.
• 3D Printer Part Cooling: Provides concentrated airflow essential for rapidly cooling extruded filament layers to prevent warping and improve overhangs.
• Small CNC Machinery: Used for cooling spindle motors or driver boards in compact milling and engraving machines.

Applications:

• Hot-End Thermal Management: Directly mount the fan to the heat sink to maintain the optimal temperature gradient.
• PCB and Component Cooling: Provide spot cooling for stepper motor drivers, voltage regulators, or microcontrollers that generate significant heat.
• Enclosed Electronics: Facilitates air circulation and heat dissipation in small, densely packed enclosures or equipment where space is limited.

Equivalent Models:

• 4020 Blower Fan 24V: The generic descriptor often used across various suppliers, covering the same form factor and voltage.
• 5015 Blower Fan 24V: However, this is a larger fan (50x15mm) often used for higher flow rates, but the 4020 serves as a compact alternative.
• Sunon / Delta 4020 Blower (24V equivalent): Other major manufacturers produce similar centrifugal fans with comparable specifications.
