Cart Pass-Through Chambers

Heavy-Duty Cleanroom Pass-Throughs for Bulk Material Transfer

Cleanroom Specialists’ Cart Pass-Through Chambers are engineered for cleanrooms that require safe, high-integrity transfer of carts, bins, and heavy equipment between classified environments. Built for ISO Class 6–8 applications, these floor-mounted pass-throughs feature fully welded 304 stainless steel chambers, UL-rated leak-proof doors, and interlock systems to minimize contamination and protect your cleanroom integrity.

Designed to support pharmaceutical, biotech, and high-volume sterile processing, our CleanSeam™ pass-through line combines long-term durability with fast, hassle-free installation and optional status indicator upgrades for smarter operation.

🔹 Key Features

  • ISO-Certified Design
    Rated for ISO Class 6, 7, and 8 environments; ideal for sterile manufacturing, pharmacy compounding, and life science applications.

  • Fully Welded CleanSeam™ Interior
    Continuous seam welds eliminate crevices where particles and microbes can collect, ensuring the chamber is easy to clean and sterilize.

  • 304 Stainless Steel Construction
    Corrosion-resistant finish withstands alcohol-based disinfectants, bleach-based cleaners, and regular sterilization cycles.

  • Floor-Mounted Design with Ramps
    Includes (2) removable ramps for seamless cart entry and exit. Designed to handle heavy equipment and wheeled materials without disrupting cleanroom containment.

  • Automatic Mechanical Interlock
    Prevents both doors from being opened at the same time to reduce cross-contamination. Optional Smart upgrade includes green/red visual indicators to notify users when it's safe to open the opposite door.

  • Leak-Rated Stainless Steel Doors
    Access doors feature UL-rated gasketing and heavy-duty lift latches for a secure seal and extended product life.

  • Gasket System
    Santoprene® “E”-shape non-outgassing gasket maintains its shape after compression and won’t warp, crack, or degrade. Mechanically attached to prevent adhesive failure.

  • Anti-Static Windows
    Doors include static-dissipative PVC windows, which prevent particle attraction and improve visibility during material transfer.
