Airtight passbox with electronic interlock

The equipment transfer passbox, also referred to as a pass-through, is an important piece of equipment that allows equipment and materials to be transferred between two zones with differing cleanliness levels or classes. It prevents contamination during equipment transfer.

• Passbox doors and casing comprise a hermetically sealed welded assembly
• Inner casing in 304 L stainless steel, satin-finish, polished, 220 grain
• Outer casing in electrogalvanized steel with powder coating (thickness 80 microns), anti-corrosion coating as per RAL colour chart

• Airtightness provided by a cellular EPDM single-hardness static seal fitted on all four sides of the frame
• Lever handle available with stainless steel faceplate lock or stainless steel pull handle
• Flush hinges with anti-friction bearings, polished stainless steel
• Sound and thermal insulation with expanded rockwool core M0 (density 130 kg/m³) or non-combustible aluminium honeycomb core (optional)
