What is a pass-through or pass-box?

A pass-through (or pass-thru) is a chamber that allows items to be moved between cleanrooms or between cleanroom and non-cleanroom areas. Less traffic in and out of the cleanroom means fewer chances for contaminants to enter. Pass-throughs can also be designed so that only one door will open at a time. This, in conjunction with higher air pressure inside the cleanroom, forces particles out when the inner door opens.

Contact CE for help determining the correct size and style of pass-through that best fit your situation.
