No matter how the external air conditions change, the indoor room can maintain the originally set requirements for cleanliness, temperature, humidity, pressure and other performance characteristics. In order to ensure the cleanliness of the workshop, a filter box is usually set in the clean workshop to control the humidity, temperature and cleanliness of the air entering the workshop before sending it into the workshop. Secondly, there may be an exhaust and ventilation mechanism near the mechanical equipment in the workshop to directly discharge the high-concentration smoke from the source for centralized treatment. Therefore, when building near the workshop, it is necessary to prefabricate various pipelines according to the standards and transport the produced pipelines to the site for installation.
