Air showers quickly and effectively remove particulate that would otherwise be carried into the cleanroom; high air-flow volume combined with high nozzle velocity provide the power and force necessary for optimal operation.
Whether the goal is high semiconductor yields or a flawless paint finish, controlled environments are integral to manufacturing processes. Air showers are vital to maintaining the clean environment; they help protect operations from the constant threat of air particulate contamination. Semiconductor, medical device, bio-tech, microelectronic, optics, pharmaceutical, aerospace, nanotechnology, and automotive industries require contaminant-free environments and use air showers as part of their operations.
Air showers are self-contained air recirculation systems installed at entrances to cleanrooms and other controlled
environments. Because people and products are the main sources of cleanroom contamination, these cleanroom entry systems quickly and efficiently remove particulate contaminants from workers or products before they enter a clean space.
Air showers blow high-velocity jets of HEPA-filtered air to remove loose particles from people and products before they enter a cleanroom. This decontamination process means cleaner air enters the cleanroom, reducing product defects and increasing production yields.
Additional advantages include longer-lasting cleanroom HEPA (high efficiency particulate air) filters because contaminant loads are lower. Without the pre-cleaning
air showers provide, the main cleanroom air filtration system would absorb the entire contamination load, which increases energy consumption and maintenance costs.
HOW AN AIR SHOWER WORKS
Air showers operate similarly to automated car wash pressure washer systems.1
In an air shower, a worker passes through the entry door and a sensor activates interlock magnets, which lock the air shower and cleanroom doors. Numerous adjustable nozzles blow high-velocity streams of Class 100 filtered air onto workers. The high-velocity air creates a flapping effect on clothing which produces a scrubbing action, removing particulates from cleanroom garments. To ensure all particulates are removed, workers raise their arms and rotate in place. Indicator lights signal the end of the cleaning cycle, and the cleanroom door opens. It takes
four to eight seconds of cleaning time and another two to four seconds for the air shower to purge contaminated air prior
to the worker exiting. Microprocessors control the cleaning and wait times.
