5.0 out of 5 stars | For ac system pulls -30 in seconds! Ran for hours no problem.
Size: 4CFM
Even though the oil leaked out and was a big mess on arrival. After the trip to Napa auto parts for premium pump oil. The thing works great. Pulled vacuum on my ac system for hours, no problem. Pulls to -30 in seconds, that’s pretty good for the awesome price tag. But they seriously need to put the oil in a container, no point in preloading a mess for us to clean up. FWI only place I could find pump oil was Napa auto parts, to avoid waiting for delivery of oil. Honestly, a good pump though, and super quiet.

5.0 out of 5 stars | Met my AC needs
Size: 4CFM
I ordered this pump so I could work on several of my cars. It arrived in fine shape, maybe just a little oil leak. It had enough oil to register just above the minimum line. Pulled a vacuum several times and it worked so that I could refill the AC system and get cool air again. Seems to work well at least for a backyard mechanic with only occasional use. Worked fine for my use.

5.0 out of 5 stars | Handy vacuum pump for Automotive AC
Size: 4CFM
I've already used this pump to evacuate and recharge an automotive AC system. It worked fine and the suction was better than expected for 1/3 hp. It does not come with oil so I suggest you purchase vacuum pump oil beforehand. It came with fittings for R 22 and R 134 a as well as other refrigerants. For 20 years I've been using an old compressor I cut out of a refrigerator to vacuum down AC systems so this compressor is quite a treat.

5.0 out of 5 stars | Excellent value single-stage pump
Size: 4CFM
The ratings on this pump exceed everything I saw in its price range. Product shipped quickly and performs excellently. Used to draw a vacuum on an automotive HVAC system. Extended 18 month warranty is a bonus. Does NOT come with pump oil. Must purchase separately.

5.0 out of 5 stars | Works but need to buy oil separately
Size: 4CFM
Works as hoped, used it for auto AC. Not too loud and seems to function perfectly. Does NOT come with special oil so maybe buy at same time or buy a unit that comes with oil so you don’t have to wait to use it like I did
