Shovels, cranes, fork-lift trucks, dump trucks and dredging equipment can all be used for heavy to very heavy remediation work. Optimal protection against the polluted substances that are released during remediation is crucial for machine operators. The BMAir MAO-5 offers them purified cabin air and therefore a healthy work environment.

The system can contain a carbon filter of up to 31 kg and can be supplemented with P1 and P3 dust filters. The very large filter volume makes the BMAir MAO-5 suitable for work activities in which high concentrations of dust are released. The extremely good value for money makes this system also very attractive. No other system offers so much protection for such a low investment.

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-5

  • 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.

The MAO-5 in a nutshell

  • The largest filter content
  • For heavily polluted environments
  • Very robust design and mounting frame
  • Available in various colours
  • Extra filters for specific sectors can be added to the system
  • Includes a BMAir control system
  • Maintenance free
  • Certified

Type of system

Pressurised filter system

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.
