![[Case Study] Adjustment of Optimal Suction Capacity for Dust Collection Hood](https://image.www.ipros.com/public/product/image/d12/2000649916/IPROS85267449027441197560.png?w=280&h=280)
[Case Study] Adjustment of Optimal Suction Capacity for Dust Collection Hood
Stable operation by adjusting the excess or deficiency of air volume! A case of selecting duct diameter suitable for the air volume.
Due to the layout of the ducts, it is often the case that the intended airflow for each hood is not achieved, leading to the issue of "not having the appropriate airflow for each hood." To address this, airflow dampers were installed for each hood. By installing airflow adjustment dampers, it is possible to adjust to the intended airflow. As a result, stable operation was achieved by adjusting the excess or deficiency of hood airflow. 【Case Study】 <Problems> ■ Although a local exhaust system was introduced and the overall fan airflow is sufficient, the airflow for each hood does not match the intended airflow. ■ When the filter of the dust collector becomes clogged, the airflow on the hood side cannot be adjusted, resulting in reduced suction power. <Benefits> ■ Stable operation through adjustment of excess or deficiency in hood airflow. *For more details, please refer to the PDF document or feel free to contact us.
