Used to minimize human entry and exit during the transfer of items in a clean room.
A pass box is used to minimize the entry and exit of people, which is the main source of dust generation, when transferring items in a clean room. We offer various types in different box sizes. As optional features, we provide sterilization lamps, intercoms, buzzers, display panels, and reinforcing legs and frames for the main unit. Additionally, the "Air Shower NPB-868J," which includes four jet nozzles attached to a standard pass box, further purifies the items and materials being transferred. Furthermore, the "Circulating Air NPB-868R" prevents contamination inside the pass box by continuously circulating the air, thereby purifying the transferred items and materials.

Company information
For sites that produce and process precision machinery, dust, dirt, and chemical substances, even if they are so fine that they are invisible to the eye, are formidable enemies. Recently, from the perspective of strengthening management through HACCP (Hazard Analysis Critical Control Point), efforts are being made in food and pharmaceutical factories to remove airborne particles and microorganisms, maintaining indoor cleanliness. Therefore, clean rooms that can remove substances at the micron level have become indispensable in these manufacturing processes. At Nitto Refrigeration, we have consistently designed, produced, sold, and provided services for clean room system equipment for over 30 years, integrating cooling technology, air purification technology, and temperature and humidity control technology at a high level.
