First in Japan. Press release on AT Barrier, a domestically produced ventilation system for underground shelters.
At Protect Arts Co., Ltd., we are a Japan-based manufacturer specializing in the design and production of ventilation and air purification systems for disaster preparedness, civil defense, and emergency response spaces such as shelters and government facilities.
A Pioneering Development in Japan
This is the first domestically produced ventilation system in Japan designed specifically for underground shelters with CBRNE protection. It is a one-of-a-kind development that meets military-grade performance standards to defend against threats such as radioactive gases, chemical weapons, and biological aerosols—all achieved with Japan-made components and specifications.
Combining Practicality and Performance
Designed to operate with tool-grade batteries, this system can be deployed immediately even in situations where power is unavailable, such as during blackouts or in remote locations. Its odor removal performance has been validated through testing that simulates long-term occupancy in shelters and temporary spaces, making it a highly practical ventilation system that also considers hygiene and psychological well-being.
Confidence in Japan-Made Quality
To eliminate "unreachable" and "unrepairable" during disasters. We have established a fully domestic system—from design and manufacturing to inspection and after-sales support—ensuring rapid response and stable supply even in times of emergency.
