ASA Series
Personnel Entry Clean Air Shower

Applications

• Pharmaceutical Prep
• Semiconductor Manufacturing
• Microelectronic Fab & Assembly

Designed to remove surface contamination from personnel entering a cleanroom. Shower is automatically actuated upon entry, releasing a bath of clean air from the side walls and ceiling. After a timed duration, the shower shuts off and allows exit. The HEPA filtered air is 99.99% efficient on .3 microns, and is re-circulated for containment. Available in two configurations: Model S (straight-thru, illustrated), and Model L (providing right angle passage).
