The BMAir MAO-7HC Truck is especially designed for the transport sector, because a robust pressurised filter system is necessary to thoroughly deal with pollution and safely transport hazardous substances. The design of this system is streamlined and can be mounted on practically any truck roof hatch. This way, drivers are optimally protected against polluted substances.

Like the BMAir MAO-6HC, the MAO-7HC has been renewed in comparison to its predecessor. Both systems are equipped with a higher filter capacity. The system is available for various vehicles, including:

  • DAF / Ginaf CF
  • DAF / Ginaf XF
  • Volvo FM
  • Scania 4-serie
  • Mercedes Actros
  • Mercedes Arocs
  • Renault T/K
  • Iveco Eurotrakker

The BMAir control system regulates the pressure in the cabin automatically and has patented filter recognition. The display of the system indicates when the Combifilter needs to be replaced. With the exception of replacing the filters, the system is completely maintenance free.

Naturally, the filtering function of all systems and filters are tested in an external laboratory. In addition, we comply with the EMC guidelines; these tests are carried out independently by TÜV Rheinland.

As worldwide market leader and trendsetter in the field of pressurised filter systems we guarantee compliance with the legal health and safety regulations. However, we do not settle for just compliance; we like to go the extra mile when it comes to the health and safety of machine operators.

Patents used for the BMAir MAO-7HC Truck

  • Filter recognition:
    Thanks to communication by means of patented filter recognition, the machine driver or safety expert can easily see on the display which type of filters are installed and how many hours these will theoretically last. This means it is no longer necessary to manually open the pressurised filter system, which reduces the risk of contact with pollutants and/or toxic substances to a minimum.

Our systems are delivered with controllers to be used in the cabins. This way, the machine operator has more protection during work activities in polluted environments. The system, being a protection device, warns the machine operator when caution is called for. You can choose between a standard model and a more customisable model with additional functions.

Our pressurised filter systems can be equipped with various filters. For extra comfort and convenience, we offer combifilters that provide protection against specific substances and vapours or gases, depending on the nature of the work activities and the concentration of the polluted substances in the hazardous work environment. The combifilters are always equipped with a P1 coarse dust filter, a P3 H13 HEPA toxic particulate filter and, if desired, an advanced carbon filter. The active carbon filter is constructed together with experienced chemists and has a very high absorption and filtration effect.
