Hygiene and well-being go hand in hand with practicality, silence and ease of use. The limits of even the most advance vacuum cleaners are surpassed by centralized vacuum systems that improve air quality in indoor environments with maximum efficiency and simplicity. A system of ducts placed along the entire residential unit culminates in a central suction inlet usually located in the basement of the house or a service room. Thus the air suctioned from any environment is conveyed to the filter bag located in the central unit. Rationality and efficiency for a functional system that guarantees excellent results.
