These enclosed chambers use powerful bursts to remove particulates from people and transport carts. Pass-throughs with an air shower and room entrances serve to protect critical and non-critical areas. Because personnel is the biggest source of contamination in cleanrooms, most methods of contamination reduction (including air showers) were designed to accommodate them. Depending on their purpose, air showers can be of different sizes and constructed. They are used by many industries. How do air showers work? Learn more below! Design and operation of an air shower Modular air shower chambers or tunnels use high-velocity streams of HEPA or ULPA-filtered, HEPA- or ULPA filter air to remove surface particulates as people and/or parts enter the antechamber/buffer room.
