This BMAir filter pressurization system is equipped for installation on the roof of construction machines. The MAO-4XL is based on the BMAir MAO-4HC. The difference between the two is that the MAO-4XL has a larger filter capacity, and can thus perform longer under much heavier working conditions.
Additionally the MAO-4XL and the MAO-5, with an even larger filter capacity, fit into the same frame. In order to upgrade the security level when working under extreme working conditions, the two systems can be easily switched.
