Sistem Air is an Italian company specialising in the design and manufacture of central vacuum systems for residential and professional applications. Today, it is among the leading European manufacturers in the sector, with a commercial presence in over 54 countries worldwide. The system conveys the collected dust through a pipe network to a central vacuum unit, where the debris is gathered and the exhaust air is expelled outside the building, preventing the recirculation of fine dust particles indoors. For over 30 years, Sistem Air has been developing high-performance solutions that combine technology, reliability and attention to detail, integrating seamlessly with contemporary architecture and advanced building systems. At Klimahouse, the company presents a concrete vision of modern living: invisible, quiet and efficient systems designed to improve indoor air quality and everyday comfort, without technical or aesthetic compromises.
