12V DC Centrifugal Blower / Turbo Fan (100x30mm)

Overview & Features When a standard cooling fan just doesn't push hard enough, the 12V DC Centrifugal Blower (often called a "Turbo Fan") delivers the concentrated, high-pressure airflow you need. Unlike standard axial fans that spread air over a wide area, centrifugal blowers pull air in through the center (the 60mm intake) and force it out of a concentrated side nozzle at a 90-degree angle. This "turbine-style" design generates significantly higher static pressure, allowing it to push air forcefully through tight spaces, narrow ducts, and dense heatsinks where regular fans would stall. Available at Tomson Electronics, this robust 12V turbo fan features a standard 2-wire configuration (power and ground) for easy integration into almost any DC circuit. Measuring approximately 100mm across with a 30mm thickness and a 55mm wide exhaust port, it is the perfect size for heavy-duty hardware cooling, DIY ventilation setups, and custom environmental control systems. Commonly searched as: 12v turbo fan, 10030 blower, centrifugal cooling fan, high pressure dc fan, 3d printer blower, squirrel cage fan. Technical Specifications Fan Type: Centrifugal Blower / Turbo Fan (Squirrel Cage Impeller) Operating Voltage: 12V DC Overall Dimensions: 100 mm × 100 mm × 30 mm Exhaust Port Width: 55 mm Intake Diameter: 60 mm Mounting Hole Distance: 100 mm Wiring Configuration: 2-Wire (Red: +12V, Black: Ground) Housing Material: High-temperature thermoplastic Common Applications Robotics & Embedded Systems: Providing directed, high-pressure airflow to cool high-current motor drivers in competitive mechanical soccerbots or keeping components cool inside the tightly packed chassis of a self-balancing robot. 3D Printing & Fabrication: Acting as a heavy-duty part-cooling fan for large-format 3D printers, pushing air through narrow custom ducts to instantly cool melted plastic, or clearing smoke from laser engraver workbeds. Aquarium Temperature Control: Creating DIY evaporative surface cooling rigs to maintain strict water parameters and prevent overheating in sensitive planted shrimp tanks. Custom Enclosures: Forcing air through tight heatsinks in custom hardware builds (like enclosed remote LoRa mesh safety devices) where standard axial fans lack the required static pressure. Frequently Asked Questions Q: What is the difference between an axial fan and a blower/turbo fan? A: Axial fans (like standard PC case fans) have blades that push air straight through the fan housing. They are great for moving large volumes of air in open spaces. Blower fans pull air into the center and fling it outward through a directional nozzle. They move less total volume, but at a much higher pressure, making them ideal for pushing air through restricted spaces or ducts. Q: Can I control the speed of this fan? A: Yes. While it only has two wires and lacks a dedicated PWM signal wire, you can still control the speed by regulating the input voltage using a standard DC motor speed controller or a step-down buck converter. Q: Will this fan run on a 5V or 9V power supply? A: It is strictly rated for 12V DC. While it may spin slowly at 9V, 5V is typically not enough voltage to overcome the internal motor resistance and get the blades spinning. For optimal performance, always supply a clean 12V source.
