97 mm fan: The fan is made of PBT plastic material, which is resistant to breakage and deformation, ensuring stable operation between -10°C and 75°C. This 12V 97 mm fan features dual ball bearings for long service life, capable of operating continuously with reliable performance. The turbine lifespan reaches up to 67,000 hours at 25°C. Faster cooling: Designed with a centrifugal fan configuration to rapidly cool and ventilate solar panels, inverters, 3D printer enclosures, and home multimedia cabinets. Can be used as a replacement fan for inflatable decorations. By generating a powerful and concentrated airflow, the 140 mm fan is ideal for removing hot air from tight spaces. Powerful performance: Compact yet powerful, this small fan delivers a strong airflow of 110 CFM at up to 6500 RPM with a maximum noise level of 53 dBA. Suitable for applications requiring high airflow in confined areas, ideal for cooling electronic components and equipment in restricted spaces. Plug and Play: Easy to install. Once mounted using the included screw kit, simply connect to a power outlet to start the fan. The power adapter enables maximum fan speed and allows the fan to be powered directly from an AC outlet. Variable speed control: Includes an adjustable speed controller with a 7.7-foot cable and on/off switch, allowing you to set the optimal fan speed for desired airflow and noise levels. Input voltage range: 100–240V AC. Compatible with standard 120V outlets to operate the 12V fan.
