The need to breathe clean and safe air is essential. The air purification systems we use are military developments and provide the best solution for protection against radioactive waste after nuclear, biological or chemical attacks. To ensure your security, we work only with licensed manufacturers from Switzerland and Israel. Each air purification system is supplied with electricity and contains two spare subsystems. One has an automatic power supply, drawing energy from a battery at times when the power supply suddenly interrupts, and the other subsystem is an emergency hand pump for long-term power outages. Тhis way you can be completely confident that you will breathe entirely purified air in the bunker. Besides that, there are several filters with different functions and degree of permeability, which the external incoming air passes through.
The air purification system is a military development that we officially import directly from the manufacturers in Switzerland or Israel, depending on the needs. All polluted air is sucked out by the fan, which then passes it through a valve. The air passes through a filter that purifies it and it becomes breathable. The system is equipped with an H14A filter of the highest class, a preliminary filter class F9 and a carbon filter capable of removing all known biological contaminants, war gases and nuclear waste from the air.
The systems are equipped with blast-protection valves to protect the bunker from sudden changes in the ambient air pressure. Nuclear weapons create a shock wave that can lead to sudden changes in atmospheric pressure (about 3 kg per square centimetre), which can spread several tens of kilometres from the detonation point. After the shock wave passes, a sudden negative pressure follows. If such waves enter the bunker, they will cause significant damage to the occupants and the equipment. Blast-protection valves are placed at the air ducts and at the exhaust pipes. Under normal conditions, the blast valves remain open and the spring valves close automatically upon high pressure.
