Taiho-door inflatable type

By filling air inside the rubber seal and expanding the rubber, the door and frame are tightly sealed. This door is easily installed, has a short installation time and high flood protection performance. Since there are no steps, which is a characteristic of locations where watertight doors are installed, they are ideal for areas where an unspecified number of people would use this door. We have a small demo machine at our Tokyo office, so please feel free to come by and see it. 

• In use
• When the water pressure was at 15m, the seal was intentionally retracted to allow water to leak through the sides of the door. The water can be stopped by expanding the seal again.
