UV222 Pass-Through Box

The UV222 Pass-Through Box is a through-wall transfer chamber for contamination-controlled environments. It installs into a prepared wall opening between a lower-grade and a higher-grade room. Integrated Far-UVC (222 nm) fixtures reduce microbial load on exposed surfaces during a preset cycle,  while integrated HEPA filtration handles the chamber air - replacing manual wipe-down at one of the cleanroom's busiest control points. 

Built for Cleanroom Transfers

Material transfer is a control point in every cleanroom operation. Tools, components and consumables can carry microorganisms on their exposed surfaces, and every transfer is an opportunity for that load to cross a classification boundary.

The UV222 Pass-Through Box applies that control to the transfer itself. Two cycle durations are set at commissioning: a longer cycle for material moving into the higher-grade room — 15 minutes by default, sized for transfers from non-classified areas — and a shorter 5-minute cycle for material moving out. The short cycle can also be run on the empty chamber between transfers. The door on the receiving side stays locked until the cycle completes; if a cycle is interrupted, the door stays locked and the load is re-run.  

Key Features and Benefits:

• Defined exposure on every transfer -  the clean-side door releases only on successful cycle completion. If a cycle is stopped, the door stays locked and the load is re-run. 

• Interlocked doors — simultaneous opening prevented under all normal operating conditions; override only through the service hatch, by trained service personnel. 

• Two configurable cycles  — long (default 15 minutes, dirty-to-clean) and short (default 5 minutes, clean-to-dirty). Durations are set at commissioning and adjustable afterwards. 

• Integrated Far-UVC (222 nm) panels above and below the load, angled toward the centre, with a perforated stainless-steel shelf so light reaches the underside as well as the top.

• Chemical-free at the transfer point — no disinfectant and no residue on the material or in the chamber. 

• Integrated air handling - HEPA filtration with an upstream activated carbon stage and variable-speed fan, running during the cycle, at idle, or in continuous recirculation.

• Pressure configurable to the zones either side, with monitoring ports for external instrumentation.

• LED countdown indication above each door — operators on both sides can see cycle status at a glance. 

• Networked monitoring — an Ethernet connection to the built-in dashboard gives cycle durations, door and interlock state, fan speed, and per-module UV intensity, temperature and uptime. 

• Configurable ventilation rates — adapted to in between any cleanroom grades.
