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 content of the bowl is discharged to the intermediate tank. As soon as the valve has closed the system creates overpressure in the intermediate tank. The outlet valve opens and the content of the intermediate tank is transported to the waste water tank.
