Atmos-Tech Pass-Thru

The through wall Pass-Thru system protects the integrity of even the most critical Cleanroom environments while allowing convenient access to adjoining rooms. The Pass-Thrus interlocking system allows only one door to be opened at a time which allows the Cleanroom air pressure to be maintained and minimizes particle migration. All Atmos-Tech Pass-thru units are constructed with smooth interior and exterior surfaces to allow for proper cleaning and sanitizing.
