SPECSTAR 110V 1/4 HP 3.5 CFM Single Stage Rotary Vane HVAC Air Vacuum Pump for R12 R22 R134a R410a Systems 330ml Oil Included

This has lasted 3 years no problem. Just don't like that there's no valve at the hose pointsBut great in the field and hasn't given me a problem. For as inexpensive as it was.

Only used once so far but wow this thing is fantastic we will see how it holds up

Great vacuum pump, I was able to reach 500 microns of vacuum quickly.

Used the vacuum pump to recharge AC in a vehicle. Seemed to do the trick but my only concern was that after pouring in the entire bottle of pump oil it barely reaches the min level on the sight glass. Will probably get more to top it off but the function seemed ok regardless.

This 2 stage SpecStar is exactly what I needed for wood stabilizing. I tried a PBAutos single stage RS2 and it worked OK but didn’t last long. This 2 stage Specstar is a workhorse, doesn’t get hot, much quieter and pulls a better vacuum for stabilizing wood in a chamber. I feel very comfortable leaving it run for long periods when making multiple color passes. With the single stage I always worried it was going to catch fire from running so hot.I read several articles that said you didn’t need a 2 stage for wood stabilizing and they might be right about “need”, but WOW what a difference in performance it makes and the SpecStar just works GREAT. I highly recommend starting with this unit if your really want to do wood stabilizing and can really get hooked especially if you start using dyes to create some colorful woods for turning.

Good

Excellent quality machine. Runs smoothly for long vacuums. It is heavy but is worth it.

This was to replace another pump that was actually slightly smaller. I didn't use it much at first. At first it worked Ok, but then after a while it started spilling oil all over the place. I should have returned it then, but I figured it was something I did wrong. I cleaned it up, verified everything put in proper oil to the proper level and it did the same the next time I used it. So not I missed the return window because I got busy on other things and so I lose my money for a pump that is useless. Wish I paid the extra $125.00 over this one and replaced the first pump with the original type... sometimes cutting costs is more expensive.
