The importance of ventilation systems for bomb shelters and shelters: ensuring air purification in protective structures
The online ventilation store Ventilator specializes in the development and supply of effective ventilation systems for bomb shelters, shelters, and other civilian protective structures.
In critical situations, ventilation in bomb shelters and shelters is one of the most important survival factors. It is the ventilation system that ensures the supply of clean air, maintains the required oxygen level, regulates humidity and removes hazardous substances from the indoor air.
Without effective ventilation, a bomb shelter must guarantee the safe stay of people, especially under conditions of chemical, biological or radiation damage. In this case, only the correct arrangement of the ventilation system — with filters, fans, valves, air filtration and regeneration — allows you to avoid the ingress of toxic substances and aerosols.
A special role is played by filter absorbers, which neutralize chemicals, dust and even small particles of debris that can penetrate after a shock wave. It is also necessary to provide a ventilation system that works autonomously, even in the absence of electricity.
Modern ventilation systems are divided into natural, mechanical and combined. Each type has its own advantages depending on the shelter device. It is important to take into account the location of the shelter, the number of people, as well as the presence of protective structures and supply and exhaust systems.
Reliable ventilation — is not just a technical detail. It is a guarantee of human protection and comfortable heating for the civilian population, who may be in shelters for a long time without access to outside air.
Types of ventilation systems for bomb shelters and shelters: features of air purification and maintaining safety
Ventilation in bomb shelters — is a critically important system that solves a number of tasks necessary for the survival of people in protective structures during emergencies. First of all, ventilation in a bomb shelter must ensure the supply of clean air and a stable level of oxygen in the room. Without regular air renewal, even the strongest bomb shelter quickly becomes unfit for human habitation.
The second important aspect is the removal of carbon dioxide (CO₂), which is formed as a result of breathing. In a closed space, CO₂ accumulates quickly, and if ventilation provides its removal ineffectively, residents experience headaches, weakness, and loss of concentration.
Ventilation systems: requirements for ventilation of bomb shelters
The ventilation system is also responsible for cleaning the air from dust, aerosols, toxic and chemical substances that can penetrate the shelter during shelling, accidents, or terrorist threats. In this case, filter absorbers installed in ventilation ducts help.
In addition, ventilation reduces humidity, which increases from breathing, evaporation and household processes. This helps to avoid the appearance of condensation, mold, fungus and corrosion.
Many modern bomb shelters provide a clean ventilation mode and an internal air regeneration mode when incoming air from radiation dust is limited or impossible. In this case, the filtration system ensures that the air is breathable.
Finally, ventilation helps protect people from shock waves, debris, radiation dust or chemical attack, thanks to protective valves, fans and carefully thought-out system design.
Types of ventilation devices for shelters and bomb shelters: valves and air purification systems
Modern shelters and bomb shelters must be equipped with effective ventilation systems, because it is ventilation that ensures the life of people while they are in protective structures. Ventilation in a bomb shelter ensures the supply of oxygen, the removal of carbon dioxide, the purification of air from harmful substances, as well as the creation of a comfortable microclimate and heating.
Natural ventilation in bomb shelters and shelters: device, features of operation and air purification in the ventilation system
Natural ventilation — the simplest and cheapest ventilation device that works thanks to the laws of physics: the difference in pressure and temperature between the outside and inside air. Fresh air enters through the intake openings, and the exhaust air — is discharged through exhaust ducts.
Advantages:
- Easy installation and maintenance
- Does not depend on power supply
- Minimal costs for equipment and operation
- Works without a fan, electronics and automation
Disadvantages:
- Dependence on weather conditions (wind, temperature)
- Low efficiency in sealed rooms
- Inability to fully purify the air
- Not suitable for shelters with a high level of protection
In a critical situation, natural ventilation cannot always provide the necessary oxygen supply or remove harmful substances. Therefore, it is used only in small storage facilities that are not intended for a long stay of a large number of people.The importance of ventilation systems for bomb shelters and shelters: ensuring air purification in protective structures

Mechanical ventilation system for bomb shelters: types of valves and filters for air purification in protective shelters
A mechanical ventilation system operates using a fan, valves, filters and sensors that allow precise control of air supply and exhaust. It can operate in several modes: normal, emergency or sealed, which is critically important in the event of a chemical, biological or radiation threat.
Main components:
- Supply fans that supply outside air to the shelter
- Filtration modules that purify the air
- Exhaust fans that remove exhaust air
- Check valves that prevent the penetration of harmful substances
- Interior air regeneration systems (in sealed modes)
Advantages:
- Controlled air exchange
- Air purification from toxic gases, aerosols, biological substances
- Maintaining optimal humidity and temperature
- Possibility of operation in filtration mode without outside air flow
- Autonomous operation using batteries or generators
Disadvantages:
- High cost of installation and maintenance
- Dependence on power supply
- Need for regular inspection and replacement of filters
In civil defense bomb shelters, mechanical ventilation is mandatory. Especially in cities, where the concentration of chemicals, emissions and dust is much higher. Systems must be designed for a large number of people — taking into account the amount of CO₂, moisture, heat release and other factors.
Requirements for the design of ventilation systems for bomb shelters and protective shelters: the presence of valves, air purification and autonomous operation
According to state standards and building codes, ventilation in bomb shelters must meet the following criteria:
- Providing clean air in a volume that covers the oxygen needs of all people
- Presence of exhaust and supply ventilation
- Filtration of outside air from radiation dust, chemical and biological substances
- Tightness of channels, filters, valves
- Resistance to shock wave, temperature and humidity
- Possibility of autonomous operation for at least 72 hours
- Air regeneration system in sealed modes
Arrangement of ventilation systems for civilians in shelters and bomb shelters: devices for effective air purification
When designing a ventilation system for a bomb shelter, the following must be taken into account:
- Number of people in the shelter
- Estimated time of stay
- Presence of external threats (chemical plants, potential areas of shelling)
- Type of shelter: temporary, permanent, deep or superficial
- Ventilation device equipment: access to filters, valves, repair hatches
Examples of ventilation systems and filters for air purification in bomb shelters: presence of valves and features of the device
Today, ready-made ventilation systems for bomb shelters are available on the market, which include:
- Filter-absorbing units (FPU-100, FPU-200)
- Vents VC, VRP, VRPD — explosion-proof
- Valves with manual or automatic control

The system may also include CO₂, temperature, and humidity sensors that allow you to monitor the air parameters in the shelter and respond to changes in a timely manner.
Conclusions on the effectiveness of ventilation systems for bomb shelters and shelters: ensuring air purification and protection of ventilation equipment ventilation in protective structures
Ventilation in bomb shelters — is not only comfort, but also the main condition for survival in an emergency. A properly selected and installed ventilation system allows you to:
- Provide oxygen
- Remove CO₂
- Protect from toxic substances
