Central dust vacuum cleaning systems provide an efficient, cost-effective solution by replacing portable vacuums with a centralized setup managed from a single point. Installed as a pipe network in industrial facilities, these systems connect to a central unit with a waste collection chamber and vacuum blower. Dust from floors, machinery, and production areas is directed to a remote collection container through wall-mounted pipes. Automatic flap valves and operator-mounted suction devices allow multiple users to clean simultaneously. Various hoses and nozzles enable effective cleaning of floors, corridors, and machinery, with low maintenance and clog-free operation. Units are generally located in basements or storage rooms, with suction pipes distributed across the facility.
