Pass Box also known as a transfer hatch or transfer box or transfer window is an essential solution for the controlled transfer of materials between environments. Our pass box is intended to reduce the danger of contamination and cross-contamination during the transfer process, thereby guaranteeing the integrity and cleanliness of your controlled areas.

Its dual-door design and interlock system provide a secure and controlled passage for transporting items between areas that have different cleanliness requirements. The interlock mechanism ensures that only one door is open at a time, avoiding contamination or air passing between the dirty and clean areas.
