Are air showers effective? Yes, air showers are effective in reducing particle contamination in cleanroom environments. They use high-velocity air jets to remove loose particles, such as dust and fibers, from individuals and objects before entering or leaving the cleanroom. The air showers are designed with multiple air jets that blow from various directions, ensuring comprehensive particle removal. The effectiveness of air showers depends on several factors, including the duration and velocity of the air jets, the cleanliness of the air, and the design and construction of the air shower unit. By controlling these variables, air showers can effectively minimize the introduction of contaminants into the cleanroom.
