Robinair (15115) VacuMaster Single Stage Vacuum Pump - Single-Stage, 1.5 CFM

I picked this pump up about 2/3 months ago solely to use for vacuum forming kydex, while a lot of companies recommend high HP pumps for kydex I’m limited to available amps on my breaker since I work out of an apartment, tried another pump before this that used about 9 amps and couldn’t get it to work at all and figured id try this pump but with worries it wouldn’t displace enough air or have a strong enough pump to get a defined mold, however like I said I’ve had it for 2/3 months and haven’t had a single issue and it works wonders for running a small business. Would recommend for people getting into vacuum forming

Have to replace the AC compressor in two cars. Instead of paying someone to vacuum and recharge, just spend the money to get a vacuum pump and a gauge set to do it myself. It pays for this vacuum pump and the gauge set for doing just one car. This comes with the proper fitting to attach to the yellow line of the gauge set. I did not know that it actually comes with a bottle of pump oil. Before it arrived, I was calling all over for the pump oil. No hardware stores, home centers, or many auto parts stores carry it. Finally found it in the NAPA auto parts store. It was a present surprise to find a bottle of pump oil in the box when this arrived.It does the job even with 1.5 CFM capacity. Just vacuum the system for half and hour after replacing the compressor and the accumulator, then shut off the gauge valves and let it sit for half an hour to make sure there are no leaks before recharging. Works great.

This worked really well for the job I needed it to complete. It was able to pull 30in vacuum on the system that I was working.

I am a nearly 30 year veteran mechanic and have used recovery and recycling machines for most A/C jobs but have used the vacuum pumps a few times over the years and this one is as good as any I have used. I purchased this one for my own personal use at home and it comes with vacuum oil and 134a adapter fitting.It is by no means the best but at the price point I think it is a great value. Overall I am satisfied.

As other reviewers have noted mine came with dings from rough handling- and though this is not any kind of commercial grade vacuum pump it is fairly expensive for the the size and vacuum capacity. The damage was definitely not do to shipping so there is an manufacturer handling issue before boxing. There was a small dent on the motor housing end cap and also a bent fin. Paid more for the Robinair brand but not inspired by the arrival condition although it was small cosmetic damage. It came with enough oil for one use and an extra fitting to hook up to an r134 gauge. Seems to work fine and to be well built.

I have used Robinair products professionally for 11 years and this vacuum pump meets all my expectations. It's quiet, runs relatively cool, with low vibrations. Pump came with 1/4" flare fitting on the inlet, an adapter to the automotive style fitting, and vacuum pump oil. I have used this on a couple of vehicles so far (one of which was a Suburban with rear a/c) and have no complaints. I was able to pull 28" of vacuum with this pump in a few minutes and hold vacuum for 45 minutes. Be aware this is a small pump (1.5 cfm) and consequently takes longer to pull a vacuum which is fine for personal use, but would recommend a larger pump for shop use. I'm very happy with this product and would recommend it to others.

I RECIEVED THIS IN ITS OWN BOX i did not open it or use it until now and it is past the 30 day window i turned it on and the fan in the motor hits the housing and makes a loud noise very disappointed i guess shipping is not very good or was sold broken

I've never worked on an A/C system before so this was new territory for me. I've done just about everything from brakes to full engine builds/installs.Anyway, my work car lost it's A/C, so rather then pay someone else to do this job, I purchaased this with a set of guages and dove in. Glad I did. The pump drew down the system in a timely manner, and I was glad to see the oil was includued. This isn't something I plan on using much, but it paid for itself after one use. My A/C is back up and going again, and more importantly, it was repaired correctly!
