Gas Filter GF-75 \u2013 ABC Protection Filter for Shelters<\/h2>\n

The GF-75<\/strong> gas filter reliably protects occupants in shelters against nuclear, biological, and chemical (NBC) <\/strong>contamination. It prevents the ingress of radioactive dust, biological aerosols, and chemical pollutants, thereby actively ensuring a controlled and safe air supply. <\/p>\n

Contaminated outside air is drawn in by a fan and initially passes through a particulate filter, where radioactive particles and biological agents are effectively retained. The air then flows through an activated carbon gas adsorption filter, which binds chemical contaminants. As a result, only filtered air enters the shelter. <\/p>\n

Design and Construction<\/h2>\n

The GF-75 gas filter features a robust, powder-coated steel housing <\/strong>designed for long-term use in civil and governmental shelter systems. Its compact design allows secure floor mounting and reliable integration into existing ventilation systems. <\/p>\n

Standards, Certification, and Type Approval<\/h2>\n

The GF-75 gas filter complies with the regulations of the Federal Office for Civil Protection (BABS).<\/strong>
Type testing is carried out by the Swiss Federal Department of Defence (VBS)<\/strong>.<\/p>\n

Approvals <\/strong>(depending on manufacturer): BZS T 92-009; BZS T 75-004<\/p>\n

BSSD ensures that only tested and approved gas filters<\/strong> are used in shelter systems.<\/p>\n

Integration into Ventilation Systems<\/h2>\n

The GF-75 gas filter<\/strong> is designed as a system component of the VA-75 <\/a>ventilation unit<\/strong>. It operates in conjunction with the VA-75 and provides the gas filtration stage for NBC protection<\/strong> within the system. This makes the GF-75 an integral part of the filtered air supply during gas filter operation. <\/p>\n
