The roller automatic outfeed pass box is a closed automatic material transfer device for areas with different cleanliness levels. It is integrated with powered roller conveyor, electronic interlock for double doors, sensor detection and PLC control system. Optional modules include laminar flow purification, air shower and VHP vaporized hydrogen peroxide sterilization.

Based on airlock isolation principle, the equipment ensures both doors cannot be opened simultaneously to block air convection between zones of different cleanliness and reduce cross-contamination.

After materials are loaded and the inlet door is closed, the system performs purification or sterilization in preset procedures. Once the process is completed and qualified, the powered rollers start automatically to convey totes or materials out for unmanned transfer. It can connect with upstream and downstream automatic conveying lines, complying with GMP and ISO14644 standards. Widely used for material outfeed in sterile pharmaceutical, medical device and biosafety laboratory cleanrooms.

Sealed chamber: SUS304/SUS316L inner tank, sealing strips, pressure-bearing airtight structure;

Powered roller conveyor module: electric rollers inside the chamber and at the docking section, drive motors, photoelectric sensors (material detection);

Double interlocked doors: inlet side and outlet side, electric/pneumatic interlock (core safety mechanism);

Purification unit (optional): HEPA high-efficiency filtration, laminar air supply, air shower nozzles, VHP vaporized hydrogen peroxide sterilization module, UV ultraviolet disinfection;

Automatic control system: PLC + touch screen, differential pressure / temperature and humidity sensors, audible and visual alarm, data logging;

Docking interface: capable of connecting with production line roller conveyors at front and rear to realize automated on-line discharging.

Automatic conveying and discharging: Powered rollers replace manual pushing and pulling, and can connect with upstream and downstream assembly lines for continuous discharging, suitable for heavy turnover boxes and bulk materials;

Contamination isolation airlock: Used for transfer between rooms of different cleanliness classes, reducing the frequency of cleanroom door opening and protecting high-grade clean environments;

In-chamber purification / bio-decontamination: Dust removal, sterilization and reduction of microbial load (air shower / VHP / UV available as optional items);

Safety interlock protection: Double-door interlock, differential pressure abnormality alarm, timeout alarm and fault shutdown;

Traceable process: The PLC records transfer batches, time and sterilization / air shower parameters to support GMP audit trails;

Airtightness maintenance: Sealed doors plus differential pressure monitoring to prevent air leakage and escape of dust / microorganisms.
