The VA 150 ventilation system<\/strong> is designed for continuous operation in protective shelters with high occupancy levels. It ensures a reliable supply of breathable air for occupants while continuously removing stale indoor air. This maintains a stable oxygen level and reduces carbon dioxide concentration. <\/p>\n During normal operation, the system supplies fresh air from outside. In an emergency, it can be quickly switched to gas filtration mode <\/strong>without tools. The changeover is performed by disconnecting the flexible hoses, enabling effective filtered air supply in the event of chemical, biological, or other hazardous contamination. <\/p>\n All VA-150 ventilation systems supplied by BSSD are manufactured according to the guidelines of the Swiss Federal Office for Civil Protection (BABS)<\/strong> and are type-tested by the SPIEZ LABOR of the Swiss Federal Department of Defence, Civil Protection and Sport (VBS)<\/strong>.<\/p>\n Approvals<\/strong> (depending on manufacturer): BZS T 87-003, BZS TE 98-005<\/p>\n The specific approval depends on the design and manufacturer. BSSD ensures that only tested and approved systems are supplied. <\/p>\n The VA 150 ventilation system is designed as a powerful standalone unit and is suitable for both wall mounting inside protective shelters and installation in separate technical rooms. For larger facilities, multiple units can be operated together as a coordinated system. <\/p>\n The system connects to a shared air intake equipped with explosion protection valves <\/strong>and an integrated air filter. Installation dimensions are standardized throughout the VA series, simplifying planning, expansion and replacement. <\/p>\n Differences between configurations\u2014depending on the manufacturer\u2014primarily relate to:<\/p>\n Pre-filters<\/p>\n<\/li>\n Airflow measuring tube<\/p>\n<\/li>\n Gas filter configuration<\/p>\n<\/li>\n<\/ul>\n The VA 150 ventilation system is designed for both electrical operation and full manual emergency operation. <\/p>\n Ventilation unit with electric motor<\/p>\n<\/li>\n Reduction gearbox<\/p>\n<\/li>\n Dynamo with sealed 5-watt emergency lamp<\/p>\n<\/li>\n On\/off switch<\/p>\n<\/li>\n Attachable hand crank for manual operation<\/p>\n<\/li>\n Airflow measuring tube with throttle valve<\/p>\n<\/li>\n Hose pair with coupling and four clamps<\/p>\n<\/li>\n Operating manual with protective cover <\/p>\n<\/li>\n<\/ul>\n In the event of a power failure, reliable manual operation remains possible.
