💨 Robinair (15115) VacuMaster Single Stage Vacuum Pump - For Efficient Single-Stage Vacuuming, Delivers 1.5 CFM Review

Haven't had to use it yet. I lit it and filled it with oil. Be sure to fill in the included oil slowly as you don't want to go past the fill line. Don't take the whole bottle.

They did very well. This device could reduce the vacuum to nearly 30 inches in a minute. After that, he had no problem working for more than 30 minutes to dehydrate him. I am very happy with this purchase. Not only that, my air conditioner now works better than it did when I bought the car new, works with new or old fittings with or without the adapter that came with it.

Perfect for my home garage. Excellent vacuum cleaner. I've learned to do my own air conditioning job and even though I've spent a few hundred dollars to buy the necessary equipment I've saved so much and more, I have a recovery tank and an air purge pump so whenever I need something – something checked in on any of my vehicles, I can restore the coolant, get the job done, and return it all at almost no additional cost.

I've used this on two different cars after repairing the air conditioning compressors in both so it's already paid off! This quickly creates a deep vacuum that is very close to 30 inches of mercury. Run it for 10 to 20 minutes and charge it again. Both machines are still blowing cold. The unit came with oil and a few small adapters to connect it to the A/C manifold and it runs fairly quietly. I would buy it again if I needed a different vacuum pump for anything.

Arrived damaged although the box was in good condition. Mostly cosmetic, but new should still be new. I unpacked it. Once oil was enough. Buy extra oil. Turned it on for a preliminary test to make sure it works and sucks. Everything looked fine. Smoked a little but from what I've read it's normal and to be expected for this type of pump. As soon as he created a vacuum, the smoke would slow down or stop. Will update the stars if there are performance issues.

I decided to invest in air conditioning instead of paying a garage to fix the air conditioning on my car. I chose this vacuum pump based on the reviews and am very satisfied. The pump works great and the price is right. It's very quiet and drains my car's system quickly. The kit includes a plastic bottle of vacuum pump oil, enough for one fill. It is recommended to change the oil after each use. The fitting on the compressor is a standard size R12 1/4". An adapter for the larger R134 fitting is

This item is amazing. I thought it would be loud like other similar brands but this pine is actually very quiet. I could fall asleep next to him. Only a slight hum can be heard during operation. I haven't set up my entire vacuum wood stabilization system yet, but so far I'm very impressed with this unit. Everyone I've asked about different brands, this one has always been the winner for budget vacuum pumps. This is MUCH better than all other cheap Chinese brands rebranding the same device. In…

Mine pulled a blocked manifold with a gauge line set at 30 inHg and hasn't complained about it. I haven't tested it on a large container yet, but will let you know if it fails. This is for a set of R134A air conditioning sensors or similar. You need to buy oil because the instructions say it needs to be changed almost immediately after filling and the first run. After changing the oil as instructed I found that the oil was dirty so it was a good idea to change the oil. The manual also says that

Pump came in a sealed box, drain plug had been snapped off and some of the threads on the housing were damaged, the hardware store next door had the correct screw, wiped the case, cleaned enough for a new screw, but had to use the oil that came with the unit to flush the sawdust out of damaged threads, used half the oil I bought to warm up the pump and drain it again to make sure there weren't any metal shavings left in the pump , first vacuum didn't hold which made me unsure if the pump was…
