Air Shower

Air showers are used to clean particles off personnel before they enter a cleanroom. It utilizes high-pressure, HEPA- or ULPA-filtered air to remove dust, fibrous lint, and other contaminants from personnel or object surfaces. To reduce the number of airborne particulates introduced, the forceful "cleaning" of surfaces is necessary before entering clean environments. They are typically used for higher classification cleanrooms (ISO-5 /class 100 cleanrooms, ISO-6 / class 1000 cleanrooms) and are very popular in the semiconductor industry. Common geometries or types of air showers include cart, single-door, straight, tunnel, L-shaped, S-shaped, U-shaped, and three-door air showers.
