1. Blade design, high pressure, large air volume, low noise and long service life.
2. The air volume control is stable and easy to operate.
3. There are many styles.
4. Strong insulation, easy installation, high reliability, high compression ratio, low bearing operating temperature, no oil and pollution in the shell.
5. The production of large air volume and high suction lies in the special design of impeller. The impeller edge of the fan has multiple blades. When the impeller rotates, due to the centrifugal effect, the air in the two blades is quickly moved to the outer edge direction, transmitting energy, and the wind pressure is quickly superposed, which forms the high pressure or high force, and the speed is increased. When the air is re introduced into the impeller by the air duct, it will be accelerated again. Due to the transfer of energy by multiple blades, the wind pressure is quickly superposed, forming a high pressure or high suction.
