HOW IT WORKS
When a flush is activated compressed air flows through the vacuum pump (ejector) and a vacuum is created in the intermediate tank. The bowl is rinsed. The inlet valve opens and the contents of the bowl is discharged into the intermediate tank. As soon as the valve has closed, the system increases the pressure in the intermediate tank. The outlet valve opens and the contents of the intermediate tank is transported into the waste water tank.
