The material shows quality in both strength defense against rusting and simple cleaning methods. The double-walled construction enables the Pass Box to survive repeated sanitary cleaning and everyday operation.
 2. Double-Walled Structure: Double walls in models protect temperature-controlled spaces and reduce noise by preventing heat loss and keeping noise away.
 3. Interlocking Doors: The safety interlocking system keeps both door panels closed during transfers so that airborne particles cannot move between chambers.
 4. HEPA Filters: HEPA systems filter incoming air through filters that capture particles measuring down to 0.3 microns to keep only sanitized air moving into the sterilized environment.
 5. UV Sterilization Lights: Advanced models of Pass Through Box now contain UV lamps to kill germs as items pass through before reaching the protected space.
 6. Temperature Control Systems: An internal temperature control system maintains heat or coolness inside the pass box which safely moves heat sensitive items.
