The Cleanroom Dynamic Pass Box is an active material transfer system designed for the safe movement of small items, tools, samples, and production materials between clean areas or between non-clean and clean areas.
Unlike a standard static pass box, the dynamic pass box integrates HEPA-filtered air circulation and an active self-cleaning system to reduce airborne particles inside the chamber before materials enter the receiving area. Interlocking doors prevent both sides from opening simultaneously, helping maintain pressure separation and minimize cross-contamination.
Constructed with smooth stainless steel surfaces and available with electronic or mechanical interlocking, the system is suitable for pharmaceutical manufacturing, biotechnology, laboratories, semiconductor production, microelectronics, and other controlled environments requiring reliable material transfer.
Shanghai Maya provides customized dynamic pass box solutions according to wall dimensions, material size, cleanliness requirements, transfer workflow, and functional configuration.
