Cleanroom Pass Box by Kambic
Cleanroom Pass Box for Contamination-Free Transfer
Designed for optimal performance in and out of cleanrooms
At Withnell Sensors, we supply a high-performance cleanroom pass box range from Kambic, designed to support contamination-free transfer between controlled and non-controlled environments. These cleanroom pass boxes (also referred to as transfer hatches) are engineered to minimise particulate ingress and maintain cleanroom integrity across a wide range of applications.
Maintaining strict contamination control is critical to product quality and process reliability. A Kambic cleanroom pass box allows materials to be transferred in and out of the cleanroom without personnel movement, significantly reducing contamination risk and improving operational efficiency in cleanroom environments.
Why choose a Kambic Cleanroom Pass Box?
Enhance production efficiency: As the exclusive UK distributor of Kambic, Withnell Sensors provides cleanroom pass boxes that are custom-designed and manufactured to the highest standards. Each unit features a high-grade AISI 304 stainless steel interior with a mirrored polished exterior, making it suitable for demanding cleanroom applications within the pharmaceutical, semiconductor and food industries.
Advanced contamination control: Kambic cleanroom pass boxes are specifically engineered to reduce personnel traffic, which is one of the primary sources of cleanroom contamination. They also prevent contamination egress to the external environment, making them suitable for use in biological safety laboratories. Large radius internal corners support effective cleaning and sealing, while the 12mm tempered glass door and innovative power-free mechanical interlock ensure reliable, safe operation.
Customisable and easy to install:Each cleanroom pass box is supplied with all required installation components as standard, ensuring straightforward integration into your cleanroom facility. A wide range of optional accessories is also available, allowing your cleanroom pass box to be customised to meet specific process, layout and compliance requirements.
