Review on π 3CFM 1/4HP Single-Stage Rotary Vane Vacuum Pump, 110V HVAC Vacuum Pump for Air Conditioner Maintenance, Food Packaging, and Medical Experiment, with Manual Valve & Oil by Giles Lacoste
Worked best in A/C line repair tools
I did a lot of research and finally settled on this pump. I used it to vacuum a mini split unit and it got it down to -30psi. Crafting requires a minimum of -10 but is awesome. What is confusing is that it has two oil filler caps. You can use any of them, but you'll have to guess why and which ones to use until you come to the conclusion that it doesn't matter! But it is one of the screw head. Otherwise it worked great! There was just enough oil in the kit to fill the MAX line, so don't spill it.
- High efficiency
- Negative result available
