[0002] Laser cutting is the most widely used laser processing technology. It is widely used in many industries.

Insufficient suction: If there is only one blower, its suction power may not be enough to completely remove all the smoke and dust generated during the processing, resulting in a decrease in the air quality in the processing area, affecting the health of the operators and the processing results.

[0005] 2. Noise problem: A single blower may generate loud noise when running at high speed, affecting the operating environment and the comfort of surrounding personnel.
