On July 22, 2025, the Nihon Keizai Shimbun introduced our AT Barrier series of disaster ventilation systems.

The article featured the performance of the AT Barrier 150, a domestic ventilation system that addresses various risks such as airborne viruses, harmful chemicals, and radioactive particles.

The world's highest level of filtering performance, which combines a cyclone separator, high-performance HEPA filter, and chemical filter, has led to its adoption as "standard equipment" in a wide range of facilities, including shelters, municipal stockpiling facilities, and corporate crisis management centers.

The "AT Barrier" series, which continues to pursue the creation of spaces that protect lives by preparing for invisible threats in the air, will continue to be expanded to a variety of applications and scales.
