Selecting A Vacuum Pump. Speed and Maximum Pressure Vacuum pumps are often rated on the flow capacity which is stated as CFM (cubic feet per minute). This references the speed at which the pump is capable of moving or removing air and is most often measured at zero pressure. A pump rated at 1 CFM will be fine for flat panel work on vacuum bags .
Dry pumps can also be fitted with booster pumps to achieve higher capacities and wider vacuum ranges. One distinct advantage is the absence of oil in these mechanisms. Any lubrication is normally contained away from the pump swept volume and is less susceptible to contamination.
