VAB VakuumanlagenBau GmbH

VAB VakuumanlagenBau GmbH, located in Muldestausee, Germany, is an ISO 9001-certified system developer for combined vacuum and gravity sewerage networks and an authorized partner of the Flovac Vacuum Sewerage System. The company provides full-scope services spanning process consulting, cost estimation, process guarantee, component delivery and installation, construction supervision, personnel training, maintenance, spare parts supply, and 24-hour emergency on-call service for all known vacuum system brands. VAB's core offering is the vacuum sewer system built to DIN EN 1091, consisting of a central vacuum station housing a vacuum tank, dual vacuum pumps, dual wastewater pumps, and an integrated control and alarm system; a network of vacuum collection piping from DN 80 laid in sawtooth profile with localized jumps to overcome elevation differences; and pneumatically actuated vacuum valves at each wastewater inlet that open automatically when wastewater accumulates in the house connection shaft, transporting it via air acceleration before closing again. For small-scale applications, VAB offers the Mini Vacuum System using one or two rotary lobe pumps to generate vacuum, housed in concrete or PE shafts of 2,500 mm diameter for shallow groundwater conditions. VAB also specializes in modernization of aging vacuum installations, operational management of existing systems, and expansion of vacuum networks, with particular expertise in challenging terrain including high groundwater, flat landscapes, hard rock, drinking water protection zones, and areas requiring sealed, zero-exfiltration wastewater transport.
