Product Description

Style: 3 CFM

Product Description

The Robinair 15300 has been performance tested to meet Robinair’s high standards. It features power and capacity for a wide range of service applications, a high CFM rating for fast, thorough evacuation and a two-stage rotary vane design. Features: Two-stage Design – Cleans the system more thoroughly than a single-stage pump, the second stage starts pumping at a lower pressure so you can pull a deeper, ultimate vacuum; Oil Drain Valve – Positioned at the bottom of the oil reservoir and angled for faster, more complete draining; Oil Fill Port – Makes adding oil simple since the port is accessible from the front or either side. The sight glass on the front of the pump shows you when enough oil has been added; Heavy-Duty Motor – High torque design for easy startup and efficient operation; and a Die-Cast Aluminum Housing – Cast aluminum housings make the pumps lightweight but durable.

From the Manufacturer

115 volt, 2-stage design. 1/2" ACME and 1/4" MFL intake fitting. No-hassle over-the-counter replacement warranty.

I originally purchased the lower model version, the 15300 3 CFM, and I wasn't really pleased with it and then I come to find that this one the upgraded version is actually a few bucks cheaper..... what? The same pump design but more power for cheaper? Yes. and it works a heck of a lot better too. Will bring any gauge to below -30 Hg within 10-20 seconds. All this being said it is amazing for Vacuum purging BHO. With the older lower model pump it could take anywhere from 5-7 hours to get some oil under 110F to not move, but with this new one I swear I can get it done in 2 hours. This thing is quiet and a beast.

Make sure you read the directions properly when adding oil. You don't just add oil until it reaches the oil fill line. You must turn the pump on, take off the exhaust fitting, and close one of the caps, and leave it running for one minute. After that one minute the oil level should be where the oil is actually at. So you need to run it for a minute to check oil levels, but other than that this thing can run for a long time and will get hot. Not a problem though cause this thing was designed with heatsync technology and stays cool everywhere else except for a few places.

All in all I loved this thing way better than the lower model and it was CHEAPER. Get this thing if you need a pump to pull -30Hg and beyond.

Ordered the Robinair instead of a cheaper no-name brand figuring it would last. The first time I used it, it worked great. Pulled over 29 in of vacuum, nice and quiet, I was very happy with it. But when I got it out a couple of weeks later to use it a second time, it would only pull 25 in. I replaced the oil, but it still would only pull 25. So I talked with Robinair tech support (actually spoke with an application engineer at the factory, not a call center in India! Gotta give them points for that!). Anyway, he thinks one of the vanes went bad and only one stage is working. I'm sending it back for a warranty replacement. Hopefully it's not a design issue and the new one will work fine. Keeping my fingers crossed.

I have been in the HVAC business for about 3 years now and this vacuum pump is not only the fastest I have seen but also the most reliable and affordable. My boss has been doing HVAC for about 40 years out of which he has owned his own business for 27. My boss had been using a 6 CFM Yellow Jacket vacuum pump for which he paid around $400. His Yellow Jacket pump was not only expensive but slow to put a system in a vacuum. Today my boss owns his own Robinair VacuMaster pump and realizes that Robinair produts are not only more affordable, reliable, and durable than Yellow Jacket's.

This thing will easily pull vacuum within minutes at most. I use it mostly to degas material in a 5 gal vessel. It has never failed to pull full vacuum. I see lots of people talking about it pulling 30+ vacuum which isnt likely. Standard atmospheric pressure is 29.92 In. Hg, so your pump is doing its job perfectly if it pulls down to the exact negative of that number (-29 in hg) and this pump has done that everytime for me. Ive run this pump degassing material for 4 straight days at a given time and the pump ran like a champ.
It will not only pull and remove all trace gas from your material but also pull all moisture from your material also. If you run concentrates, then you have stumbled onto exactly what you were looking for! Save time and order yourself a quart of the vacuum pump oil too, youll need it after a few vacuum runs. Change your oil when you notice it starting to get too discolored. After all, its the lubrication for some highly precise veins spinning inside under tight tolerances.

I ordered the Robinair 15800 Vacuum pump Brand new . It was DOA , I followed Amazons instructions for returning the pump.
They returned the pump and sent me out a new one RIGHT AWAY. It works great and good value for the money .

Although there was the hassle in getting a pump that did not work and having to go through returning it,(these things happen).
Amazon's well thought out return system kept My Stress Factor to a minimum.
I Thank Amazon for a great customer service experience even under these circumstances!

Got this for our HVAC division. It's solid construction and quick. Come with three size connections. Bit heavy but it's worth gold in the field. Can't be happier.

This review is not so much about this product as much a reflection of Robinair's business practices through online sales. I have three of their products previous, two two stage 3cfms and this was going to be my second 8cfm. I was buying it because I love the power my 8cfm has over the smaller pumps while being not much louder to operate. So I ordered this vacuum excited to add it to my family of pumps.
When it arrived I noticed something strange. It had thick dark golden oil in the oil sight, right out of the box. I flipped through the instructions (i have never seen this before in a "new" pump) and sure enough in nice bold dark print the Robinair Owners Manual states "item ships without pump oil" and to add pump oil before the inital use of the pump. This residual dark oil freaked me out mostly because the oil Robinair itself sells for use in its pump (and the only oil I use) is almost perfectly clear. The oil in my pump looked more like honey than pump oil. So i drained the pump and refilled it with the new robinair oil included with my pump and tested the pump on my chamber for barely an hour. The pump worked well at first pullling the vacuum to close to 29, then as I let the pump run I noticed to hear a whine or stress sound coming from the motor of the pump, and then it just up and died on the stop, probably within 65 minutes of me pulling it out of the UPS box. Now the reason I wrote this review is because I feel that after examination of my pump, the weird gunk in it when they shipped it to me, and its performance compared to my funcation 8cfm pump, I concluded that this "new" pump has seen way more wear and tear than my old pump. Noticeably after running such a short time the "new" pump has already given the pump oil a burnt smell.
