That’s the impressive part of the Venturi kit I bought. It’s got a vacuum regulating switch so it only passes air when it needs to refresh the vacuum. And it’s got a couple PVC storage tanks to create a buffer. It does require you to put some umph into the assembly to be sure it’s as air tight as you can get it. Any leaks are noticeable in how often the system cycles. I’m pretty impressed with its efficiency though!
