Air showers are used as purification equipment in industries such as pharmaceuticals, healthcare, raw and cooked food processing, precision instruments, instrumentation, and aviation. Their main purpose is to remove dust, hair, and other particles from the surface of operators' clothing using clean air before they enter the workshop. Primary and intermediate-efficiency filtration removes these particles, preventing them from entering the workshop and ensuring hygiene standards are met to improve product quality. Air showers use a PLC intelligent control system with automatic sensing and air showering functions. The air shower time and blowing speed can be adjusted within a certain range.
