AutoVac’s eye-catching V1 Vacuum Arch provides two designated hose drops to each vacuum stall — one for each side of every vehicle. This V-shaped design is compatible with high speed self-serve vacuums as well as central vacuum systems. And because each lane receives two hoses from one primary separator, our V1 Vacuum Arch is ideal for offering metered central vacuums. Through our propriety IntelliVac technology, the carwash owner determines how much free vacuum time each customer receives. Suction for a particular stall is activated by the customer (either by keypad, coin/token, or ground loop sensor) and when time us up, suction shuts off. Customers can either purchase more time, or leave the stall and free it up for the next vehicle.
