Adding to answer above, I used to use an old R-12 Refrigerant tank (about the size of a grill propane tank) to act as my vacuum reservoir. This allowed me to pull the correct amount of vacuum and the tank would help that vacuum to last longer, so I didn’t need to run the pump continuously. FWIW, I used to vacuum-bag wood veneer and fiberglass/spectra/carbon cloth onto Styrofoam airfoils when make RC sailplanes. Too much vacuum would crush the Styrofoam and distort the desired airfoil.

Also, you could always piggyback more than one vacuum reservoir can for added capacity.
