Aluminum linear air vents highlight the characteristics of linear design. Aluminum linear air vents can be divided into 0-degree linear vents and 30 degree linear vents, which can be used for indoor linear and circular air supply and return devices. They can be installed on side walls, floors, and ceilings. Aluminum linear air vents are all made of aluminum profiles and can be processed into fixed or detachable, curved angle air vents according to user requirements. The maximum length of the linear air outlet is 3.5 meters. For larger lengths, it can be segmented and connected. To meet the user's selection requirements for the air outlet, the outer frame width of the linear air outlet has two specifications: wide frame and narrow frame.
