New in the BMAir collection are the MAO-3 Cab Guard with PAC Smart Control. Specially designed for the increasing demand for compact and smart systems. Under the modern, robust, plastic housing is a uniquely shaped self-cleaning HEPA filter with incomparable capacity. A compact, full carbon filter can also be installed within this unique concept. The new dimensions generate a filter contact time that is superior to the current products in the market. Hazardous substances and vapors do not stand a chance!

The MAO-3 Cab Guard comes standard with the new PAC Smart Control. All data can be read clearly on the 3.5′ high resolution LCD display. With fully automatic filter communication and intuitive operation, the operator can easily send all relevant information via QR code with their own smartphone to the safety manager, project manager or employer. Filter types, serial numbers and events are continuously monitored and securely stored in the standard datalogging module. The PAC Smart Control is IoT ready, which also allows real-time data transfer.

With the new generation of BMAir products, you can manage your supply of filtered cabin air without difficulty or worry!

Patents used for the BMAir MAO-3 Cab Guard

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.

Bottom suction:
The air is sucked through the under-side of the system. Thanks to the vibration of the system and gravity, the coarser dust particles fall down immediately instead of accumulating in the filter. The result is a filter with a longer lifespan.

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.
