Our Pressurized Filtration Systems are standard equipped with an A.O.C. control. This monitoring device controls air quality in the cabin. The system is designed to maintain a preset value of 120 Pa. in the cabin. The A.O.C. will automatically turn on when the vehicle is started. At the same time the A.O.C. checks the presence of filters in the unit. It will give a signal if there aren’t any filters present. We offer different types of A.O.C. controls. We started with the A.O.C. Green V2, then the A.O.C. V4 Basic, Plus and Premium. In 2016 we developed a new A.O.C., the A.O.C. Green V3. This control is almost equal to the V2. While the maindrive of the V2 is mounted inside the pressurized filtration system, the maindrive of the V3 is mounted inside the A.O.C. so it is no longer part of the filtration system. Optional for all variants:

• An external warning signal which is installed on top of the cabin. This warning will activate if:
  • the level of contamination is too high,
  • there are no filters in the unit,
  • the pressure is too high or too low.
• An additional module is available with multiple gas sensors to measure more gasses in your cabin.
