The Robinair RA15601 is most definitely a premium vacuum pump, and most definitely something to compare to other vacuum pumps. This model includes a two stage design, where a deeper ultimate vacuum is produced due to the second stage pumping at a lower pressure. The vacuum pump has a simple to use isolation valve to isolate the pump from the system under vacuum to provide a simple way to measure the rate of rise.
