Why Fans With The Same Power Deliver Different Ventilation

Performance? Avoid Power-only Selection for External Rotor Axial Fans

Many purchasers find that two fans with identical power deliver totally different ventilation effects after installation. Combining years of manufacturing experience of external rotor axial fans, Hangda Fans shares key knowledge to solve this confusion.

It is a common mistake to select fans merely based on motor power. Power reflects energy consumption instead of ventilation capacity. Air volume and static pressure are the decisive indicators. When pipelines are long with multiple elbows, insufficient static pressure will lead to poor exhaust performance, even if the power meets requirements.

Taizhou Hangda Electromechanical specializes in ventilation equipment. Our external rotor axial fans adopt optimized impeller design to balance air volume and static pressure, widely used in refrigeration equipment, workshop ventilation and fresh air systems. We support customization on voltage and protection class. Products are certified with CE and CCC for global projects.

We recommend customers confirm pipeline layout, working temperature and ventilation demand before purchase. Our technical team provides professional matching solutions. Proper fan selection guarantees stable ventilation and reduces long-term energy cost.
