運作原理: 揮發性有機廢氣透過引風機，經初級過濾器, 可有效地被活性碳吸附 (或者被熱氧化設備RTO, 直燃CO, 觸媒氧化RCO, 紫外線光解UVC等系統分解及破壞) 後，使原帶有揮發性有機物之氣體成為潔淨空氣並排放至大氣。

Principle of Operation: By using the industrial fan, the VOC can be effectively led to the pre-filter system and absorbed or decomposed by the activated carbon (or RTO, CO, RCO, and UVC) installed in the job-site.
