Before placing the air duct in place, the water level and elevation of all supports should be checked, and the firmness of the supports should be checked. There are two methods for placing the air duct: direct and lifting. For ducts with small cross-section and low orientation, manual positioning can be used, which only requires the installation of simple scaffolding. When the cross-section of the air duct is large and the pipe section is long, methods such as pulleys, chain blocks, and large ropes can be used for lifting. Century Star introduces that in order to facilitate the positioning of the air duct, it is generally used to hang the air duct on a scaffold and then lift it onto the air duct bracket

全部通風工程需求和水簾合作運用，在夏日酷熱的時分可將車間內溫度控制在28攝氏度以內。但人體的涼快感受可與空調比較，稍長時間對著水簾的人會感受冷而受不了。

All ventilation projects require cooperation with water curtains, and the temperature in the workshop can be controlled within 28 degrees Celsius during the scorching summer heat. But the coolness of the human body can be compared to air conditioning, and people who face the water curtain for a slightly longer time will feel cold and cannot bear it.

通風管道在運輸過程應有防止損傷風管的保護措施。榫接風管的連接在榫口處涂膠粘劑，是為增強接頭處的強度。當風管采用地面預組裝后架空安裝時，限制預組裝的長度是為了遮免風管因自重產生的彎曲而破壞構件接口。玻璃纖維復合板風管端口為切割面時，在裝配法蘭連接件前應將管端切口面用膠帶或膠液進行封堵，才能防止玻璃纖維外露和飛散。

Ventilation ducts should have protective measures to prevent damage to the ducts during transportation. The connection of the mortise and tenon air duct is coated with adhesive at the mortise to enhance the strength of the joint. When the air duct is installed overhead after ground pre assembly, limiting the length of pre assembly is to prevent the bending of the air duct due to its own weight from damaging the component interface. When the end of the fiberglass composite board air duct is a cutting surface, the cutting surface of the pipe end should be sealed with tape or glue before assembling the flange connection to prevent the fiberglass from being exposed and flying.
