With the increasing demand for evacuation facilities due to climate change, pandemics, and geopolitical risks, many ventilation systems are manufactured overseas and there are concerns about supply and maintenance. The AT-Barrier is a CBRN-compliant high-performance filter that can be used not only in times of disaster but also for air purification during normal times.
CBRNE-compliant units
ATバリア150は、
CBRNE（化学・生物・放射性物質・核・爆発物）への対応を想定して設計された独自ユニットを搭載。
非常時の汚染された空気を効果的に浄化します。
Peace of mind not only in emergencies but also in everyday life
ATバリアの性能は災害時だけにとどまらず、日常の空気中に含まれる臭気やアレルゲン、PM2.5などの微粒子やガスにも効果を発揮。
平時から安心して使用できる常設型の空気浄化システムとしても機能します。

PM2.5
A cyclone separation mechanism and pre-filter remove coarse particles, and a HEPA filter filters fine particles with high precision. Finally, a chemical filter adsorbs toxic gases and odor components. Step-by-step filtering addresses a wide range of air risks, from disasters to everyday life. It provides a safe and clean air environment.
chemical filter
Special military grade chemical filters are used to filter out gaseous toxic substances such as hydrogen cyanide, hydrogen cyanide, and VX gas. VOCs, odors, and other gaseous toxic substances in addition to toxic gases such as hydrogen cyanide and VX gas The filter physically and chemically adsorbs and removes gaseous toxic substances such as VOCs and odors as well as toxic gases such as hydrogen cyanide and VX gas at the molecular level.
HEPA Filter
Medical grade high performance that removes at least 99.971 TP3T of particulates 0.3 μm and larger HEPA filter is adopted. Viruses, bacteria, mold spores, and PM2.5, PM2.5, and even particulate radioactive materials (a cause for concern in the event of a nuclear disaster).
Pre-filter
Captures coarse particles such as dust, hair, pollen, and fiber debris in the air at the initial stage. Highly durable filter. Substantially improves filter performance and life at the later stages.
Cyclone separation mechanism
Centrifugal force physically removes heavy particles, sand, volcanic ash, and pollen from the air.
A cyclone separation mechanism and pre-filter remove coarse particles, and a HEPA filter filters fine particles with high precision. Finally, a chemical filter adsorbs toxic gases and odor components. Step-by-step filtering addresses a wide range of air risks, from disasters to everyday life. It provides a safe and clean air environment.
Designed to be battery-powered and hand-crankable for use during power outages, it provides reliable ventilation and air purification even in environments where infrastructure is limited, such as disaster areas and evacuation centers. In addition to viruses and dust, it also handles odors, helping to create a safe breathing space. The product is designed to provide both hygiene and comfort even in limited spaces.
- Private shelters for individuals
- Disaster shelters for municipalities and public facilities
- Evacuation centers (schools, hospitals, government buildings)
- Corporate BCP bases (data centers, manufacturing, financial institutions)
- Temporary medical clinics and waiting areas at medical and welfare facilities
In shelters and enclosed spaces, odors such as sweat, excrement, and putrefaction can accumulate, increasing psychological stress and hygiene risks.
AT Barrier 150 is also highly effective in removing odors generated in closed spaces for long periods of time. In fact, we verified the removal performance against typical odor components such as sweat, excretion, and putrefaction odors in a chamber designed for evacuation shelters and shelter environments.
hydrogen sulfide
Hydrogen sulfide is a peculiar malodorous substance, like rotten eggs, that is produced when wastewater or sewage decomposes.
Increased concentrations may affect the respiratory and nervous systems.
AT-Barrier150 was highly effective in reducing the concentration of hydrogen sulfide by more than 90% within about 30 minutes of the start of the test.
methyl mercaptan
Methyl mercaptan is a strong malodorous substance that is produced during food waste, wastewater, and food spoilage. In a demonstration test, AT-Barrier150 removed more than 991 TP3T of methyl mercaptan in 40 minutes.
acetic acid
Acetic acid is the substance responsible for the sour odor produced by sweat, body odor, and decaying food, and can cause discomfort and mental stress in enclosed evacuation spaces. In enclosed evacuation spaces, it can cause discomfort and mental stress. AT-Barrier150 has been shown to significantly reduce acetic acid concentrations by more than 70% in just 10 minutes.
isovaleric acid
Isovaleric acid is a substance that causes strong unpleasant odors resulting from sweat and steamed shoes. In a closed environment, the odor tends to accumulate particularly easily and can cause a psychological burden.
ammonia
Ammonia is a substance with a stinging odor derived from sweat and excretions. In enclosed environments for long periods of time, there are potential hygienic risks such as eye and respiratory irritation, etc. Demonstrations of AT-Barrier150 quickly and effectively reduced ammonia concentrations, which are considered very difficult to remove.
