Pass Box by Kambic
Pass box for contamination-free transfer
Designed for optimal performance in and out of cleanrooms
At Withnell Sensors, we provide a range of pass boxes brought to you by Kambic. These transfer hatches are designed to effectively control the ingress of particulate contamination into cleanrooms and other controlled environments. Maintaining contamination-free conditions is crucial for the integrity of your products and processes. Kambic pass boxes allow materials to be transferred into the controlled environment without the need for personnel movement, significantly reducing contamination risks.
Why choose a Kambic cleanroom pass box?
Enhance production efficiency: At the exclusive UK distributor of Kambic, we bring you pass boxes that are custom-designed and built to the highest standards. These units feature high-grade AISI 304 stainless steel interiors and mirrored polished exteriors, which makes them ideal for the most demanding environments across the pharmaceutical, semiconductor and food industries.
Advanced contamination control: Kambic cleanroom pass boxes are engineered to minimise personnel traffic as this is typically the primary source of contamination. They also protect the external environment from contamination egress, making them suitable for biological safety laboratories. The large radius corners ensure that the pass box offers easy cleaning and sealing, while the tempered 12mm glass door and innovative, power-free mechanical interlock provide reliable operation.
Customisable and easy to install: Kambic’s range of pass boxes comes equipped with all the necessary installation parts, included as a standard procedure. Yet, there are a variety of accessories available ensuring that you can customise your cleanroom pass box to meet your specific needs.
