Clean Room Talk-Throughs —
Modular Clean Room Accessories

• Ideal for cleanrooms, laboratory and hospital isolation areas, and other restricted environments
• Mounts on 7.75" (197 mm)-diameter cut-out (custom installation panels available for other cut-out requirements)
• Mechanical model features overlapping clear polycarbonate diaphragms for clear communication and visibility

Terra's Cleanroom Talk-Throughs give you a clear line of communication into your cleanroom. Noncontaminating materials and construction techniques ensure cleanroom compatibility.

The standard mechanical model features a clean plastic frame and a combination of transparent polycarbonate and mylar diaphragms. It allows workers on both sides of a cleanroom wall to communicate freely, thereby reducing the need to enter the cleanroom or to rely on a cleanroom telephone.

The unit is easy to mount in either a standard cleanroom wall or a Terra hardwall modular cleanroom. It requires a 7.75" (197 mm)-diameter cut-out and six screws. The solid thin-mylar diaphragm seals the opening to hold the positive internal air pressure. Max. outside diameter: 10" (254 mm). Diameter of grille: 6.5" (165 mm). Screw hole pattern: 7.25" (184 mm).
