The vacuum level needs to be adjusted. We use our vacuum pressure valves inline with the vacuum pump and the process. Our vacuum pressure valve acts as a restriction to the process by limiting the amount of vacuum. The vacuum generator method is used when a vacuum pump is not available or only shallow vacuum
