Gas Filter GF-150

Gas Filter GF-150 – ABC Protection Filter for Shelters

The GF-150 gas filter reliably protects occupants in shelters against nuclear, biological, and chemical (NBC) contamination. It prevents the ingress of radioactive dust, biological aerosols, and chemical pollutants, thereby ensuring a safe and controlled air supply.

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.

Design and Construction

The GF-150 gas filter features a robust, powder-coated steel housing designed for long-term use in civil and governmental shelter systems. Its solid construction enables secure floor mounting and reliable integration into high-performance ventilation systems for larger shelters.

Standards, Certification, and Type Approval

The GF-150 gas filter complies with the regulations of the Federal Office for Civil Protection (BABS).
Type testing is carried out by the Swiss Federal Department of Defence (VBS).

Approvals (depending on manufacturer): BZS T 92-010; BZS T 89-009

BSSD ensures that only tested and approved gas filters are used in shelter systems.

Integration into Ventilation Systems

The GF-150 gas filter is designed as a system component of the VA-150 ventilation unit. It operates in conjunction with the VA-150 and provides the gas filtration stage for NBC protection within the system. This makes the GF-150 an integral part of the filtered air supply during gas filter operation.

In particular, the combination of the VA-150 ventilation unit and the GF-150 gas filter ensures compliant switching from fresh air mode to gas filter mode in accordance with BABS requirements.
