Regardless of the recovery machine you use, you’ll get a faster recovery if you remove the Schrader cores. You’ll also benefit from using a high-quality filter-drier to filter out contaminants before they reach the machine or the tank.
Bert and Jesus ensure that they have a proper setup with as few variables as possible so that they produce the best, most honest results. The Fieldpiece probes attached to the origin tanks are responsible for showing the pressure throughout the test. There are also gauges attached to the recovery tanks to measure the pressure of those tanks during recovery.
After the scales are cleared, the hoses are purged, and the equal tank capacities are confirmed, the race is ON! NAVAC maintains a comfortable lead over Appion throughout, and the race is over when the first Fieldpiece probe hits zero. NAVAC wins by an easy margin of 9 minutes!
Once the recovery is over, Bert purges the machines to get any extra refrigerant out. He and Jesus share their personal thoughts about each machine.

Just a few comments sticking up for the G5 Twin. With California putting the brakes on HFCs. Having a recovery machine that can recover A2L refrigerants is probably going to be important. The G5 Twin is one of a few recovery machines that can recover A2L refrigerants. I have been looking, but haven’t seen any documentation that the NRDD is rated for A2Ls.
Also as a side note. The G5 Twin doesn’t need to purge, it doesn’t allow refrigerant to enter its crankcase, so there’s nothing to purge. Saving nine minutes is cool and all ,but I’m going to stick with my G5 for now.
