通风道是通风管道的简称，是工业与民用建筑的通风与空调工程用金属或非金属管道。  通风管道是为了使空气流通，降低有害气体浓度的一种市政基础设施。通风管，风管制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品国家现行标准的规定，并应用出厂检验合格证明，材料进场时应按国家现行有关标准进行验收。
Ventilation duct is the abbreviation of ventilation duct. It is a metal or non-metal duct for ventilation and air conditioning engineering in industrial and civil buildings. Ventilation pipeline is a municipal infrastructure for air circulation and reducing the concentration of harmful gases. Ventilation pipes, sheets, profiles and other major finished materials used in the operation and installation of air ducts shall conform to the provisions of the current national standards for design and related products, and shall be inspected and accepted according to the relevant national standards when materials enter the field.
