The technology behind the solution

  • 1. Air inlet

    FS 35’s air inlets are located on the sides on the front for unobstructed and optimal intake. The inlets are protected by a front cover to minimize the sound level of the unit.

  • 2. Filtration of particles

    With the help of a multi-stage mechanical filtration system using ePM1 50% (F7) and High Protection HEPA 13 filters, airborne particles are captured and removed from the air. Carbon filter for gases and odors can be added as an option.

  • 3. Cleaned air is returned to the environment

    After the air has been cleaned from harmful particles, it is returned to the room. The air outlet, located on the top of the unit, is designed to efficiently distribute the air in the room.
