Modern civil defence shelters require ventilation systems capable of maintaining stable airflow under both normal and emergency operating conditions. The EBL 50 High-Pressure Ventilation Blower with Manual Backup is a radial ventilation blower developed for use in CBRN filtration systems and other air filtration applications where high static pressure is required. According to the manufacturer, the blower is designed to move air efficiently through ducts, filters, blast valve

Modern civil defence shelters and protected facilities require reliable air regeneration systems capable of maintaining safe indoor conditions during periods when fresh air cannot be supplied from outside. The ARC CO2 6000L Modular CO₂ Scrubber is designed specifically for this purpose, providing controlled removal of carbon dioxide (CO₂) while supporting safe occupancy in enclosed environments.

Reliable ventilation is one of the most important engineering systems in civil defence shelters, bunkers and protected facilities. The EBL 36 High-Pressure Ventilation Blower is a compact radial blower designed for ventilation and air filtration applications where stable airflow and high static pressure are required. According to the manufacturer, the unit is tested and certified for professional use and is compatible with CBRN filtration and ventilation systems. Atmas Group

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
