Fume Extraction Facts on Blowers


Chau Vo

Chau Thien Vo is an inventor, industrial designer, and is the Vice President of Engineering and Product Marketing for PAT Technology Systems. Chau brings 19 years of extensive experience in designing air purification and fume extraction systems, having worked in both North America and Europe. He blends design, engineering, product marketing, and creative thinking strategies in leading PAT’s technical team to consistently output innovations that clean air.

Blowers generate the airflow and vacuum pressure required to pull the air from the laser cabinet and through filters. High-end systems have high-pressure blowers that have at least 1,000 watts of power to maintain adequate initial airflow for longer periods despite heavy soiling of the filters. 

Be aware that lower cost systems that have power ratings significantly below 1,000 watts (and even less pressure capabilities) have adequate initial airflow but their performance drops off more quickly than high-powered ones. This shortcoming substantially increases filter consumption and therefore increases operating costs.
