Review on 🔧 High-performance AUTOGEN 4CFM Single-Stage Air Vacuum Pump - Ideal for HVAC/Auto AC Refrigerant Recharging Manifold Gauge Set by Robert Tirona

Gauges work great and aren't cheaply built. As well as some other brands. Sadly I have to say. The vacuum didn't work. After all that running around looking for a good vacuum oil pump. Filled it up and let it run for a few minutes before hooking it up to the sensors. (To keep the oil circulating) Thought maybe it smokes to keep the oil running but after I shut it off. Leave to cool so it dries well. I connected it to the sensors to start the process. The vacuum did not tremble and began to smoke again. (This time with a burning smell.) Worth the money if only the vacuum worked.
