Western States Sales, a distributor of cleanroom equipment and supplies introduces 30 styles of cleanroom pass thru’s. The Pass Thru is designed specifically for transferring of parts and equipment in and out of a cleanroom. This in turn reduces the need for people to enter the cleanroom and reduces the contamination. The pass through chambers are used in less critical controlled environment areas to the most stringent cleanrooms.

A standard single door pass through is available in polypropylene or stainless steel.
The stainless steel pass thru is constructed using welded, extremely strong and easily cleaned. The complete unit is metal with the exception of the safety glass viewing window. A mechanical interlock prevents both doors from being opened at the same time which keeps the cleanroom from loosing any pressure. The polypropylene pass thru is ideal where corrosion is a concern. The standard pass thru is a wall mount.
