Pass Box

Yorco Pass Box Introduction

A Pass Box is an essential requirement for Clean Rooms, OT’s and other Sterile Areas. These have Doors on Both sides. These are used to transfer materials between two clean rooms of different cleanliness classes or from a non-sterile area to a sterile area or vice versa.

These form an air lock and when one side door is opened to keep or remove material, the other side door automatically locks so there is no through pass of air from one area to another. It is also used in BSL labs to prevent Hazardous organisms escaping out during material transfer.

Pass Boxes are two types (i) Static or Passive Pass Boxes (ii) Dynamic Pass Boxes

Static Pass Boxes are air locks with UV sterilization inside.

Dynamics Pass Boxes on the other hand provide HEPA Filtered Vertical Air Flow air inside and protect the material being transfer from any contamination. When one door is opened the HEPA filtered air under positive pressure inside is partly allowed to escape out, giving an air curtain effect outer door opening and preventing outside contaminated air to enter the Pass Box and eventually escape into the other room when the other side door is opened.
