Pass-Through Chambers for the Modern Pharmaceutical Cleanroom
Germfree has leveraged our decades of facility design experience to develop a pass-through (airlock) that is uniquely engineered to meet the demands of a modern pharmaceutical cleanroom. All stainless steel construction with coved interior and exterior corners and a pharmaceutical grade finish make these pass-through boxes the most cleanable and robust on the market.

Application
For use in hospital and pharmaceutical cleanrooms to maintain control of particulates as materials are passed from one room to another. Pass-through boxes reduce traffic within the cleanroom while expediting the transfer of product, supplies and equipment. These units are designed to fit seamlessly into both new and existing cleanroom facilities.
