Vacuum Drainage - Central Vac Units

Model L380 - Evac Horizon System

The Evac Horizon System uses differential air pressure to transport waste water upward, to the overhead piping network, unlike the conventional gravity flow of underground drainage piping. Vacuum is generated by (3) 5HP liquid-ring pumps in the collection tanks and throughout the entire vacuum piping network. Waste water is collected and held in (2) 40-gallon tanks, then later discharged at a predetermined volume, to the building sewer system. Power Options: 460V | 230V | 208V
