Interlocked Pass Box

Introduction:

The Interlocked Pass Box is an auxiliary equipment used in cleanrooms. It is mainly used for transferring small items between clean areas, as well as between non-clean areas and clean areas, so as to reduce the number of times the cleanroom door is opened and minimize contamination in the clean area. Pass-through boxes are widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing plants, LCD manufacturing, electronics factories, and all other places that require air purification.

Product Advantages:

The Interlocked Pass Box provides a robust barrier against contamination during material transfer, offering distinct operational and safety advantages.

1.Mechanical Interlock Device:

The mechanical interlock prevents both doors from being opened at the same time, ensuring safety and peace of mind.

2.Transparent and Wide Glass Window:

The large viewing window provides a clear, unobstructed view for easy observation, ensuring safety and reliability.

3.Sealing Gasket:

Full-perimeter sealing gasket made of safe, non‑hazardous material. Qualified and reliable for airtight performance.

4.Power Interface:

Convenient to use and easy to replace.

5.UV Germicidal Lamp:

Built‑in UV germicidal lamp provides full‑coverage irradiation with no blind spots, effectively eliminating bacteria.

Application Areas:

Designed for critical controlled environments, the Contamination Control Pass Box is deployed across industries where material integrity and zone isolation are non-negotiable.

The cleanroom pass-through boxes are widely used in microtechnology, biological laboratories, pharmaceutical factories, hospitals, food processing plants, LCD manufacturing, electronics factories, and all other places that require air purification.

Packaging & Shipping:

To ensure zero damage during transit, we employ customized industrial-grade packaging: the unit is wrapped in dust-proof PE film, reinforced with thick corrugated cardboard and a wooden frame, and protected with high-strength corner guards. Shock-absorbing materials and secure fastening are applied internally. Each box is clearly labeled with the model number, installation orientation, and fragile warnings. We collaborate with globally recognized logistics partners to offer air, sea, and land freight options, including door-to-door delivery and insurance services. Standard delivery time is 15-30 working days, with expedited options available. Real-time shipment tracking is provided throughout the journey.
