The cargo air shower is a necessary passage for cargo to enter the cleanroom, and it can reduce the contamination problem caused by cargo entering and leaving the cleanroom. The two doors of the cargo air shower are electronically interlocked, which can also act as the airlock room to prevent unpurified air from entering the cleanroom. The high-tech cargo air shower produced by our company is equipped with an intelligent voice prompting system, which can give voice prompts when blowing. The clean airflow filtered by HEPA filter is blown toward personnel from all directions by rotatable nozzles to effectively and quickly remove dust particles, and the air with dust particles is filtered by primary- and high-efficiency filters again and then recirculated to the shower area.
