(1) Air supply, including ventilation, such as fresh air and exhaust, this range is very wide, such as the factory floor, production site air, due to the generation of harmful gases need to be discharged outside, but also need to send outdoor air to the room. At this time, it is necessary to use an air delivery pipe with a large flow rate and a small pressure. The spiral fire damper is very suitable. Generally, a galvanized iron pipe is used, and a stainless steel pipe is used in a corrosive and particularly humid place.
