The FVZ-98M unit is intended for ensuring the filtration, ventilation and air overpressure generation in mobile COLPRO equipment (combat vehicles, APCs, box bodies, containers) and serves for the personnel protection against the NBC weapons impact (chemical agents, radioactive fallout and biological aerosols). The FVZ-98M unit uses effectively the sorption capacity of the collective filter by detection of air quality in the crew compartment through CO 2 sensor and filters only such air volume, which is necessary in the selected unit operation mode. Internal overpressure regulation is attached to the vehicle speedometer.

The FVZ-98M unit can be used in an environment with extreme dust content. It has the system of internal diagnostics. It is possible to install the unit outside of the object or into the crew compartment.

FVZ-98M unit can operate in the following modes:

  • Ventilation (3 stages);
  • Risk of the NBC use;
  • Using of the NBC weapons (contamination);
  • Extra dangerous situations;
  • Hermetic sealing (FVZ-98 unit inlet and outlet closing).
