We have developed the KleanLabs clean room pass box product line for ISO-14644 or GMP certified applications. All KleanLabs clean room pass through boxes are manufactured in custom sizes and comply with the ISO 14644 standard, providing a safe and efficient solution for material transfer within the clean room environment.
During the design phase, as an experienced clean room manufacturer, we have focused on ease of installation, so that our pass boxes can be built into any kind of structure from modular cleanroom systems through drywall to sandwich panels. Pass through boxes are marketed in passive and active models with a filter which can be integrated into an already-existing ventilation system. This way clean room pass through boxes become a vital part of the clean room with optimal air exchange and filtration.
Clean room pass boxes ensure the safe and hygienic flow of both materials and equipment within the clean room, and also facilitate the flow of material in and out of the clean room, using hermetically sealed spaces to minimize contact with the outside environment. We mitigate the risk of cross- contamination by using a KleanLabs clean room sluice. Moreover, our pass through boxes are highly customizable. For instance, they can be equipped with a UV lamp or its own filtration and ventilation as in case of the active model. By using KleanLabs clean room pass through boxes, you can minimize the unnecessary entries and exits from the clean room environment, thus saving both energy and costs.

Integrated fan/filter units with H14 filtration (99.99%) deliver directed, independent airflow without external ducting.
Mechanical/electronic interlocks (with timer option) prevent simultaneous door opening and protect room differentials.
Options include trolley-ready, threshold-free, 3-door wall connections, and “combi” material/trolley layouts.
Every unit is built to size for your wall thickness, opening, and material-handling workflow.
We design and build ISO 14644-compliant cleanroom products in Europe and ship worldwide.
Kleanlabs designs and qualifies its cleanroom equipment to ISO 14644-1 and EU GMP Grades A–D with defined particle limits for ‘At Rest’ and ‘In Operation’. The four types of pass-through chambers comply with different levels of ISO standards. While static and semi-active pass-through chambers are usually suitable for clean rooms according to the ISO 7 category, active and dynamic pass-through chambers satisfy the requirements of ISO 5 – ISO 6 clean rooms.
Maintaining the highest levels of cleanliness and preventing cross-contamination are paramount in the world of controlled environments. Cleanrooms depend on precise regulation of temperature, humidity, and airborne particles to protect…
Pass-through chambers (also called pass-through boxes) have become a ‘must’ in many industries over the years. When creating a production process, material flow must be designed in accordance with the…
