الوصف
The 7020 round cooling fan is a mainstream standard axial fan in the 70mm series, with overall dimensions of 70mm×70mm×20mm, belonging to the industry-standard medium-thickness DC cooling fan category. This model optimizes the thickness of the ultra-thin 7015 fan, increasing overall airflow and air pressure without significantly reducing installation space, resulting in superior cooling performance. The product features a DC brushless motor, ensuring stable operation and low vibration. It supports all mainstream voltages including DC 5V/12V/24V/48V and offers two optional structures: oil-impregnated bearing and dual ball bearing.

Ultra-thin standard size, perfectly suited for confined spaces
70×70×15mm is the industry-standard ultra-thin fan specification. The standard circular frame and universal mounting holes allow direct replacement of the same model 7015 fan on the market without requiring modifications to the holes or structure. The 15mm ultra-thin thickness perfectly fits devices with limited internal space, solving the problem of thicker fans not fitting. Installation is simple and replacement is convenient.
Multi-voltage coverage, universal for multiple scenarios
Comprehensive coverage of mainstream DC voltages: 5V, 12V, 24V, and 48V. 5V is suitable for small digital devices and smart home devices; 12V/24V are mainstream industrial voltages, suitable for power supplies, inverters, and industrial control equipment; 48V is suitable for new energy and automation equipment. All voltage specifications meet the different power supply needs of residential, commercial, and industrial applications.
Dual Bearing Options,Quiet Operation and Long Lifespan
The sleeve bearing version offers lower operating noise and affordability, suitable for indoor equipment and short-term operation. The dual ball bearing version is wear-resistant, high-temperature resistant, and vibration-resistant, supporting 24/7 continuous operation and offering a longer service life. It is suitable for high-load and harsh industrial conditions, allowing users to choose freely based on their operating environment.
Flame Retardant and Safe, Stable Operation with Low Failure Rate
The entire unit is made of high-grade PBT flame-retardant material, which is high-temperature resistant, anti-aging, and has good insulation properties, effectively avoiding the risk of high-temperature fires in the circuit. The built-in DC brushless motor eliminates carbon brush wear issues, ensuring smooth operation and low vibration. Even after prolonged operation, it is less prone to stalling or abnormal noises, significantly improving safety.
