Painted Cold-Rolled Steel Pass Box 1160x1060x1090mm | Extra-Large Cleanroom Transfer

304 SS Pass Box 1160x1060x1090mm | Extra-Large Cleanroom Transfer

Engineered for stringent contamination control, the Convex Door Mechanically Interlocked Pass-Through Window ensures safe material transfer across cleanroom environments while adhering to ISO 14644-1 standards. Ideal for pharmaceutical, biotechnology, and electronics industries, this system combines robust construction with advanced functionality to meet the demands of sterile workflows.
The dual-material design features an outer cold plate baking paint for corrosion resistance and an inner 304 sanding stainless steel finish, delivering a smooth, non-porous surface that resists particle buildup and simplifies sanitization—critical for GMP-compliant settings. The convex door design minimizes recessed areas, enhancing cleanability, while double doors with observation windows provide clear visibility during transfers, improving operational safety and efficiency.
A mechanical interlock system guarantees only one door opens at a time, eliminating cross-contamination risks, a vital requirement in sensitive industries. Durable stainless steel handles ensure reliable, long-lasting performance even in high-traffic cleanrooms. This pass-through window seamlessly integrates into cleanroom layouts, offering a hygienic, efficient solution for transferring sensitive materials, lab equipment, or sterile components. Trust in its precision-engineered design to maintain contamination-free environments while optimizing workflow productivity.
