Description

Technical Field

[0002] An air duct is a pipeline system used for air transportation and distribution; there are two types, composite air ducts and inorganic air ducts, which can be classified according to cross-sectional shape and material; according to cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and oval air ducts.
