Introduction The EBL 300 High-Pressure Ventilation Blower is a radial blower designed for use in CBRN filtration systems and other ventilation and air filtration applications. According to the product description, it generates airflow at high static pressure, allowing air to move through ducts, filters, valves and other ventilation system components. Atmas Group The EBL 300 is designed for applications where airflow must be maintained against the resistance created by filtrat

Introduction The BVNC 40 Overpressure Blast Valve is a normally closed valve designed to maintain and control differential pressure levels inside a shelter while protecting the internal space against external blast-wave pressure. According to the product description, the valve operates automatically. When positive pressure inside the shelter reaches a predefined overpressure level, the valve releases air from the protected space. This function supports controlled air release

The AFU 1200 is an advanced NBC / CBRN (Chemical, Biological, Radiological and Nuclear) filter designed for use as part of air filtration and ventilation systems installed in safe rooms, civil defence shelters, bunkers, industrial facilities and other protected environments. According to the product information, the AFU 1200 is a standard filter for use in CBRN filtration systems. It can also be integrated into other types of compatible systems or used to replace existing fil

Ventilation openings are an important part of protected facilities because they must allow the movement of air while maintaining the required level of protection against external hazards. The BVNO 1000 Blast Valve is a normally open, dual-action automatic valve designed for ventilation systems in protected spaces. According to Shelter Shop, the valve allows air to move in and out of the protected space during normal operation and automatically closes the air opening when expo

Maintaining breathable air quality inside enclosed shelters is one of the most critical aspects of life-support engineering. During prolonged operation in lock-up mode, carbon dioxide (CO₂) generated by human respiration gradually accumulates and must be removed to maintain safe atmospheric conditions. The ARC CO2 4800L is a professional carbon dioxide removal system (scrubber) developed by Atmas Group specifically for civil defence shelters, bunkers and industrial protected

Modern civil defence shelters, bunkers and protected facilities require ventilation systems that maintain normal airflow while automatically protecting the protected space during a blast event. The BVNO 2900 Blast Valve is a normally open, double-action blast valve designed to automatically close under blast wave pressure, protecting the interior against both the positive and negative phases of a blast wave. According to the manufacturer, the valve is intended for ventilation

Modern civil defence shelters, bunkers and protected facilities require ventilation systems capable of maintaining continuous airflow while automatically protecting occupants during blast events. The BVNO 2600 Blast Valve is a normally open, dual-action automatic blast valve designed to permit unrestricted airflow during normal operation and automatically close when exposed to blast wave pressure. According to the manufacturer, the valve protects the internal space from both

The DPG-A Differential Pressure Gauge is a mechanical instrument designed to measure and monitor differential pressure in protected shelter environments. According to the product description, the gauge is intended for monitoring the pressure difference between shelter compartments, such as the main shelter chamber and an airlock, as well as between a protected area and the outside environment.
