Uses and Features

The filter adsorption device is a kind of collective protective equipment installed in ships, protective engineering, and vehicles. Its function is to filter and purify poisons, biological warfare agents, and radioactive dust in the outside air, and send them into a confined space for personnel to breathe. At the same time, an overpressure is created inside the system, which prevents the infiltration of contaminated air. The products are mainly used in places prone to leakage and volatilization of poisonous gas or chemical raw materials, such as chemical plants, laboratories, warehouses of hazardous chemicals, emergency shelters, underground positions, civil air defense projects, and other places.
