Air Curtains & Screens (Manufacturing) is a subdivision of the Industrial and Commercial Fans and Blowers and Air Purification Equipment (Manufacturing) industry. This industry involves the manufacturing of air curtains and screens that are used to separate two different environments while allowing the free flow of air. Air curtains are typically used in commercial and industrial settings to maintain temperature control, prevent the entry of insects and dust, and reduce energy costs. Air screens, on the other hand, are used in residential settings to provide a barrier against insects and other outdoor elements while allowing fresh air to circulate.
