DC 3 Blade Cooler Fan Propeller, 55mm

This DC 3 Blade Cooler Fan Propeller with a 55mm blade length is built for larger air-moving applications than a standard toy fan propeller, such as DIY air coolers, blowers, and larger model builds that need noticeably more airflow. Its 2mm centre hole fits directly onto the shaft of common small DC motors.

Three plastic blades work together for smooth, stable rotation once spinning, generating more air displacement than smaller propeller designs thanks to the larger 140mm overall diameter. This makes it well suited to DIY cooler projects, hobbyist blower builds, and larger educational science and technology demonstrations where meaningful airflow matters.

• 3-blade plastic design – balanced, efficient rotation
• 55mm blade length – generates stronger airflow than smaller propellers
• 2mm centre hole – fits standard small DC motor shafts
• 140mm overall diameter – suited to cooler and blower applications
