This equipment is used to test vacuum tightness of toilet bowls and bidets.
Through simple and fast operations, you can check whether there are any leakages due to hardly detectable cracks inside the bowl.
The test bench is equipped with a vacuum pump together with pressure accumulator.

B11 is a (Siemens) PLC controlled bench, where the operator needs only place the work piece and caps; the machine then closes the valves, waits for stabilization time and checks actual tightness.
When the test is OK, a green light will appear and send a signal to any peripherals (e.g. label printing).
