Museum Air Shower (for artifact archives, document repositories, ancient book storage) and cargo shower products are versatile local purification devices installed between clean and non-clean areas. When personnel or goods need to enter the clean area, they must pass through this device. Air is filtered through high-efficiency filters and then ejected from rotating nozzles in all directions onto people and goods, effectively and rapidly removing dust particles from the surface of personnel and carried items, thereby blocking dust from entering the clean area. The device also functions as an airlock, preventing untreated air from entering the clean zone and avoiding air convection between clean and non-clean areas that could affect the environmental parameters of the clean area. The materials used for air shower equipment include steel plate with baked paint structure, wall panel structure, stainless steel plate structure, etc. Air shower methods include unilateral showering, bilateral showering, bilateral and top showering, etc. Options for door operation include automatic, manual, and interlocking functions. Multiple air showers can also be combined into an air shower passage according to needs. Air shower (cargo shower) rooms can be custom-designed and manufactured based on site conditions and user requirements. Door opening and closing methods include manual single-side doors, manual double-side doors, automatic double-side doors, automatic rolling doors, revolving doors, overlapping automatic doors, etc. For security considerations, explosion-proof glass access control designs can be added, giving the air shower dual functions of purification and safety. The museum air shower is installed at the main entrance of the artifact storage room, filtering and removing dust carried by personnel and goods through air showering. It also serves as an airlock, preventing air convection inside and outside the storage room from affecting the constant temperature and humidity environmental parameters. The air shower series products developed, designed, and produced by our company, after introducing and digesting Japanese technology, have reached international advanced levels in structure and craftsmanship, material selection and automation, function and quality, etc. They are widely used in various fields such as cultural relic protection, electronic communications, instrumentation, aerospace, pharmaceuticals and food, automotive manufacturing, fine chemicals, etc.
