-Japanese technology for the Japanese environment.

In April 2025, Protect Arts Inc. began marketing the first domestically produced shelter ventilation system in Japan, the AT Barrier. In the field of ventilation equipment for shelters, which until now has been dominated by overseas products, this product, which has been developed, manufactured, and offered domestically, will make it possible to better secure breathing in emergency situations. In this column, we will introduce the importance of ventilation systems and the features of AT Barrier in detail.

Ventilators are "life-saving devices

When you hear the words "nuclear shelter," you may think of thick steel doors, concrete walls, and filter systems. However, "ventilation" is the most important factor to actually make it a safe space for people to live in.
In an enclosed space, oxygen is depleted and carbon dioxide accumulates. In addition, the outside air is more than likely contaminated with radioactive materials and chemical gases,Without safe ventilation, the room is "just a closed room.The first is the
Therefore, in shelters, ventilation systems are not just for comfort,Equipment that plays a central role in life supportIt is.

Conventional wisdom: "Shelter = we have to rely on foreign-made equipment."

The development of nuclear shelter culture in Japan has been slower than in countries such as Europe, the United States, Israel, and Switzerland, where nuclear shelters have been developed as a national policy. In particular,For ventilation systems, we have had to rely on foreign products for many years.was going on.
Although foreign-made shelter ventilation systems have high performance, they are subject to the following challenges.

High unit price and transportation costs
The design is based on European standards, making it difficult to adapt to Japanese housing conditions.
Time-consuming and costly to repair or order replacement parts
Risk of overseas supply network being cut off in case of emergency

In other words, Japan's dependence on imported ventilation equipment has created a situation in which the country is not equipped with the equipment it intends to have.

AT Barrier: Japan's first domestically manufactured ventilation system for shelters

In order to break through this situation, we have developed the "AT Barrier. This is the first of its kind in Japan,Ventilation system for shelters planned, designed, and manufactured entirely in JapanThis is a breakthrough in a field where foreign-made products have been the norm.

Main Features

High-performance CBRNE-compliant filter
Prevention of external contamination by positive pressure ventilation system
Designed with the Japanese environment in mind
Multi-power supply (battery and hand-cranked) for emergencies

These specifications are in the form of "ventilators suited to the Japanese climate," which could not be obtained with imported products.

Why is it important to be "domestically produced"?

Not to mention the performance of the ventilation system,The fact that the product is "domestically produced" itself is of great significance as a contingency measure.We have a

1. immediate responsiveness for repair and maintenance

To complete all processes from manufacturing to support in Japan,Quick response for parts replacement and maintenanceThe "outage period" due to transportation delays and stock-outs is drastically reduced. The "outage period" due to transportation delays or stock-outs is drastically reduced.

2. suitability for housing

Another major advantage is that the design is based on the structure, space limitations, and sound considerations of a typical Japanese wooden or RC house.

3. supply stability during disasters

Even in the event of a contingency, in a situation where international transportation stops,Domestic manufacturing makes it easy to forecast supply and accommodate national and municipal stockpiling plans.It is.

The idea of protecting the air and breathing

Behind the development of "AT Barrier" is the question, "What really protects people in times of emergency? After many measures and studies, Protect Arts Co,Creating an environment where Japanese people can continue to breathe with peace of mind in their own countryWe have been working toward this goal.
Air is invisible. However, it is first and foremost at risk in the event of a disaster. That is why,Protecting the air is "the foundation of disaster preparedness."We believe that the "one" is the most important factor in the success of the project.

Be "prepared" in the true sense of the word.

Until now, in Japan, "the only way to purchase ventilation equipment for shelters was to purchase it from overseas. However, with the advent of "AT Barrier,Independence of ventilation = independence of breathingis now within reach in Japan as well.
Breaking away from dependence on imports and obtaining peace of mind through domestic production. We need to be truly "self-reliant" in disaster preparedness. AT Barrier" is a product that makes this step a reality.
