Product Description

Product Overview

- Low noise, high efficiency, large airflow, high pressure, minimal vibration, long service life, detachable feet for flexible installation.
- The fan impeller undergoes automatic punching and cutting, followed by mechanical insertion. It is then rigorously balanced to minimize vibration, ensuring stable operation and exceptional durability.
- The motor is made from Y2 aluminum alloy die-cast material, significantly reducing its weight for lightweight design, easy installation, and an aesthetically pleasing appearance.
- Widely used in telecommunications, power generation, electrical engineering, electronics, geology, coal mining, shipbuilding, paper manufacturing, and other related industries.
- Particularly suitable for machinery and general ventilation applications such as printing, plastics, packaging, film blowing, drying, and cooling.
