The Biobase AS-1P1S is a critical decontamination solution designed to minimize particulate contaminants carried by personnel entering a cleanroom environment. This air shower serves as an automated passage where high-speed, HEPA-filtered air effectively blows dust and microorganisms off clothing before entry. The system features a photoelectric sensor for automatic operation and a circulation wind design that maintains the cleanliness of the shower area even when not in use. Constructed with double doors featuring an electric interlock to prevent cross-contamination, the AS-1P1S includes an LED display with adjustable blowing times ranging from 0 to 99 seconds. Achieving Class 100 cleanness levels, this air shower is an essential component for laboratories, pharmaceutical facilities, and microelectronics manufacturing plants where strict purification standards are mandatory for workplace integrity.
