Unhtd 15"H 171"W 18"D Alumin Air Curtain: Ambient Air, Std Profile, For 14 ft Opening, 9,944 cfm

Ambient air curtains create a wall of air that helps keep air from one space from entering another without a physical barrier. They are mounted above a door or entryway and use untreated ambient air to create a vertical air-based curtain. This barrier reduces air exchange between the two spaces and helps to keep insects and other pests from crossing the curtain.
