Central dust removal systems, also known as central vacuum systems, consist of a vacuum host, pipelines, inlets, and components, and are categorized into household and industrial types. Household system hosts are typically installed outdoors or in equipment rooms, connecting to vacuum inlets in various rooms via sealed pipelines. Anyone can perform full or partial cleaning at any time with simple and convenient operation. During cleaning, dust is drawn into the host through the pipelines, avoiding secondary pollution and noise interference. Industrial systems, such as SINOVAC, employ high negative pressure design (1000–5000mmH?O) and are suitable for industries like electronics, food, and pharmaceuticals, using filter cartridges or fabric bags to filter dust.

Household systems offer suction power up to five times that of traditional vacuum cleaners, capable of removing particles larger than 0.1μm. They are suitable for residences over 100 square meters and require professional design and installation. In many real estate projects, they have become essential equipment for enhancing living quality. Industrial systems utilize multi-stage centrifugal fans or vortex fans, with some configurations incorporating cyclone separators for secondary dust removal.
