Ventilation calculations are based on many factors, including the number of occupants, the location, and the technical features of the facility. Specifically, it is important to consider whether the space is used exclusively as a bomb shelter or serves other purposes during peacetime (parking, operating room, playroom, storage, etc.).
Enclosed shelters are designed to accommodate people for up to 48 hours, making proper ventilation essential. To meet these requirements, the SM-SH-03 supply unit was developed.
Using the SM-SH-03 supply unit ensures a continuous supply of clean air into the shelter, which is a critical factor for survival. Another advantage of this unit is that it comes equipped with a manual fan drive. In the absence of electricity, the manual drive allows the supply unit to continue operating, ensuring reliable ventilation under all conditions.
