Review on 💨 Robinair (15115) VacuMaster Single Stage Vacuum Pump - For Efficient Single-Stage Vacuuming, Delivers 1.5 CFM by Dustin Miller

Mine pulled a blocked manifold with a gauge line set at 30 inHg and hasn't complained about it. I haven't tested it on a large container yet, but will let you know if it fails. This is for a set of R134A air conditioning sensors or similar. You need to buy oil because the instructions say it needs to be changed almost immediately after filling and the first run. After changing the oil as instructed I found that the oil was dirty so it was a good idea to change the oil. The manual also says that the first solution to almost any problem with the operation of the device is to change the oil. Find out.
