Structure Composition<\/p>\n
An automatic lift pass box generally consists of a cabinet structure, lifting system, interlock system, control system, purification & disinfection system and sealing system.<\/p>\n
The cabinet is mostly made of SUS304 stainless steel, with smooth inner walls. Round corners and dead-space-free design are adopted at the bottom and corners for easy cleaning and dust accumulation prevention. Transparent tempered glass viewing windows are fitted on both side doors to observe the internal status conveniently.<\/p>\n<\/li>\n
The lifting system is composed of a motor, guide rails, door panel, transmission mechanism and sensors. The door panel moves up and down along the guide rails driven by the motor for automatic opening and closing. Some models are equipped with lifting platforms to adapt to material transfer at different heights.<\/p>\n<\/li>\n
The interlock system includes mechanical interlock and electronic interlock. Mechanical interlock realizes physical locking through connecting rods or latches. Electronic interlock adopts electromagnetic locks, control boards and indicator lights to ensure both side doors cannot be opened simultaneously.<\/p>\n<\/li>\n
The control system usually includes dual-side control panels, door opening buttons, foot switches, sensor switches, indicator lights and intercom devices. Operators can select the control mode according to on-site habits.<\/p>\n<\/li>\n
The purification and disinfection system can be equipped with UV germicidal lamps, fans, HEPA filters, air shower nozzles or laminar air supply units for surface disinfection of goods and self-cleaning of cavity air.<\/p>\n<\/li>\n
The sealing system comprises door seam rubber strips, door frame sealing strips and cavity sealing structures. It guarantees the airtightness of the cavity when the door is closed and reduces air exchange between clean zones and non-clean zones.<\/p>\n<\/li>\n<\/ul>\n

Main Functions<\/p>\n
The core functions of the automatic lift pass box are isolation \u2014 purification \u2014 transfer<\/strong>. During transfer, one side door opens first; goods are placed inside and the door is closed. After the disinfection or self-cleaning procedure is completed, the other side door opens for goods pickup. The two doors are always interlocked and cannot be opened at the same time. The electric lifting door reduces manual door-opening actions and the risk of contact contamination. Safety devices such as infrared anti-pinch and touch rebound prevent personnel pinching or goods damage. If fitted with laminar flow or air shower function, clean airflow can be formed inside the cavity to reduce particles brought in by goods. If equipped with UV lamps, the cavity and goods surface can be disinfected when the doors are closed.<\/p>\n Core Parameters<\/p>\n Key parameters for selection: internal & external dimensions, cleanliness class, filter configuration, air velocity, interlock type, lifting control mode, safety protection, material & sealing, power supply, power and noise. The standard type is mainly for isolated transfer. The air shower type removes dust on goods surface by high-speed clean airflow, with nozzle wind speed generally above 20 m\/s. The laminar self-cleaning type maintains high cleanliness inside the cavity; the working zone wind speed is about 0.3\u20130.5 m\/s, and some models can reach ISO Class 5.<\/p>\n Application Scenarios<\/p>\n![\"\"](\"https:\/\/www.bacintl.com\/wp-content\/uploads\/2026\/10\/Parameters-Application-Scenarios-767x431.jpg\")
