  • It's a bit different than the normal
Size: 8CFM2S
What I expected was this thing to run for 30 to 45 minutes as needed and then close my gauges to hold and then shut the unit off myself. What happens is it runs until it can't pull anymore and then it shuts down and closes its own valves which is very weird. It holds pressure and if there is a leak it will kick back on. But it runs for about 15 to 20 minutes I think the longest I've had it running was 25 on a 95 ft line set. Seems to be working great though just a little bit different than the normal. ... show more

  • The pump is a bit rattly…
Size: 5CFM2S
I was pleased to see thee pump arrive..hurrah! Then I read the manual and see “DOES NOT SHIP WITH OIL” And then read further to the phrase “DO NOT RUN WITHOUT OIL OR THE PUMP WILL OVERHEAT”. (Enthusiasm wanes). So i go back online to order the only oil they recommend…($150 per quart!!!)….’come-oooon maaaan!’ And end up ordering a decent premium oil for $18 quart…and find out the Harbor Freight compressor oil for $10 per quart will do perfectly! Put in the correct amount of oil and plug in then switch on..grinding rattling noises for the first 10 minutes as the sloppily machined bits shave off rough spots and smooth out. I didn’t expect a sewing machine but I paid a lot extra-DOUBLE- the cost of the cheap one so I would have a long-life machine….which I highly doubt by the sound of the start up. The caps all have to be replaced with brass caps and O rings to seal when not all ports are in use. The plastic caps are a joke and do not hold vacuum.. If you only want to use this for your air conditioning unit on your car once every couple of years this will work fine. If you’re trying to build your own milking machine or a vacuum chamber for a wood shop or metal shop….keep shopping….or better heat gut an old throw away refrigerator and hook up the refrigeration pump using the vacuum side…that what I’m going to end up doing as I sit this on the shelf as a pretty lesson in supply side economics and disappointment. ... show more

  • Order metal caps... you'll thank me!
Size: 7CFM2S
Good: It seems to be overkill to use 7CFM pump on a small mini-split but I had other uses that it'll work great on. I liked how it had a universal adapter built into the head... Other: However, no one seems to sell the 3rd of the 3 brass caps used for sealing the unused port. Totally out of stock of the convenient 3-pack-on-a-chain on Amazon, though that's not Autogen's fault. If you offered accessory kits like the Schrader valve removed and adapters+hoses, might get some upsell. Bad: The plastic caps are pretty certain to not hold a strong vacuum, making an otherwise nice pump fail to perform as well as it can. I finally found the 3rd cap (that is only used for AC unlike the other two flare fittings) and got it working. ... show more

  • Received a damaged or defective item.
Size: 8CFM2S
The media could not be loaded. I received the product I ordered in a timely manner. I did not use it as not everything was in place. Finally, I tried to use it. The word is ‘Tried’. It did not work. It hummed; the cooling blades did not turn. Apparently, it was either defective. I suspect someone swapped a good one with a damaged one. I drained the oil I added and repackaged. I contacted Autogen to consult how to repair. Autogen customer service was very nice and wanted to send a replacement. I probably should have taken the replacement offer. I returned the vacuum pump bought a different 2 stage pump as I needed to do my work quickly. If my vacuum pump, which is a very cheap one, breaks down, I would replace it with one by Autogen. After all, AS by a trust worth maker is important. ... show more

  • IT CAME UNDER-FILLED WITH OIL
Size: 5CFM2S
The pump arrived with barely enough oil. With low oil level, the pump was noisy and inefficient. With the oil at the top of the allowable range it is much quieter. You should have a container of vacuum pump oil on hand when this pump arrives. When used with low restrictions (no schrader valves, and no core depressors) and a short big bore hose with a 3/8" SAE fitting on the pump end this pump does not heat up excessively. I am consistently able to achieve a vacuum of below 200 microns. I suspect that the reviewers whose pumps are overheating are using restrictive hoses and fittings which make achieving a low vacuum difficult with any pump, thus causing the pump to run longer etc. I deducted a star for flimsy plastic fittings that go on the unused ports. ... show more

  • Vacuum pump
Size: 8CFM2S
I've been a mechanical contractor for 46 years and have used many vacuum pumps. For the money this is one of the best pumps I've used.

  • Buy additional oil!
Size: 7CFM2S
If your vacuum pump is like mine, it will arrive with the oil pre-fill coating the inside of the bag and box it came in. In other words, but pre-oiling the pump, it all just leaks out during shipping and it will come empty but covered in oil.

  • Not a 2-stage, but great customer service
Size: 5CFM2S
After an oil seal went bad on it, I finally opened it up. To my surprise, it is NOT a 2-stage pump. It is only a single stage. That explains why I struggled to get lower vacuum. Update: The customer service from the seller was Exceptional! Was willing to work with me to be able to to get me up and running properly. They are currently looking into what happend with this particular model, and as to why there was a discrepancy. On a side note, the 7CFM model IS a 2-stage out of the box. ... show more
