Review: Good price, works great, Paid for itself the first week. - Nice, Brand name, Light duty pump. Used it 3 times already and found it to be more than adequate. Easily pulls the rated vacuum AS LONG AS YOU HAVE NO LEAKS. Follow proper repair and charging procedures to avoid poor results and shortening the pumps life. Due to the design of the a/c charge hose fittings, it's easy to have leaks that are hard to detect, which will make the pump look weak. Aside from a defective unit, this is probably the issue with a lot of the "won't pull the rated vacuum" reviews on here. Even though Robinair is a BIG name in the industry, I think this unit is priced fair for something made overseas for occasional use. I'm a Certified Master Technician and Instructor with 35 yrs experience and I researched and purchased this unit for home use. I use the more expensive Robinair equipment at work because they are more reliable in a shop environment. Quality control on products made outside the U S is always a problem, but so far so good. BTW, these units do get hot, make some strange noises at times and can give off a mist and smell. Perfectly normal, just means it's working correctly. Review: Great Purchase - This model cost a little more than most but it works great in my vacuum chamber that I set up for stabilizing wood. So far I have used it three times for 12+hour long sessions with no problems. A little noisy but that is expected. Great machine up until now I was renting the free loaner from Oreillys that I considered just purchasing it since I already had it in hand but glad I didn't. The Robinair pulled more suction and just seemed better built. ## Features - Robinair's VacuMaster Single-Stage Vacuum Pump is designed for air conditioning and refrigeration service; featuring a single stage rotary vane design, 8.5 ounce oil capacity, and non-skid feet - 3 CFM free air displacement; factory rated to 75 microns - 1/4 HP, 110V/60Hz thermally protected motor - Features an inlet fitting engineered for maximum airflow, while preventing oil backflow, and finned aluminum surfaces that dissipate heat faster, keeping the pump cooler and extending life - 1/4 inch flare and 1/2 inch ACME inlet fittings, easy to read sight glass, easy access oil fill port, and angled oil drain valve for faster, more complete draining of the reservoir ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005CO9GX6 | | Best Sellers Rank | #163,904 in Automotive ( See Top 100 in Automotive ) #66 in Air Conditioning Vacuum Pumps | | Brand | Robinair | | Customer Reviews | 4.5 4.5 out of 5 stars (759) | | Date First Available | July 11, 2011 | | Is Discontinued By Manufacturer | No | | Item Weight | 18 pounds | | Item model number | 15310 | | Manufacturer | Robinair | | Manufacturer Part Number | 15310 | | Model | VacuMaster Single Stage Vacuum Pump - Single-Stage, 3 CFM | | Product Dimensions | 13.2 x 4.8 x 10 inches | | Special Features | Wheels | | Voltage | 110 Volts | | Wattage | 110 watts | ## Images ![(15310) VacuMaster Single Stage Vacuum Pump - Single-Stage, 3 CFM Silver - Image 1](https://m.media-amazon.com/images/I/914fMuutwLL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price, works great, Paid for itself the first week. *by M***. on February 27, 2014* Nice, Brand name, Light duty pump.

So far I have used it three times for 12+hour long sessions with no problems. A little noisy but that is expected. Great machine up until now I was renting the free loaner from Oreillys that I considered just purchasing it since I already had it in hand but glad I didn't. The Robinair pulled more suction and just seemed better built. ### ⭐⭐⭐⭐⭐ Robinair, a Bosch Automotive Service Solutions brand *by T***P on April 4, 2016* Surprisingly, this pump performs above my expectations for its specs and price tag. The unit comes with a 1/4" fitting already installed for the older R12 1/4" gauges instead of a dual port fitting (both 1/4 & 1/2) as shown in image. I have a set of CPS MA1234 guages that has a 1/4 " female fitting on the yellow hose and they hooked up to the pumps fitting w/o using the supplied r134a 1/2" straight adapter. The r134a adapter should be in the box.. Easy oil fill, dosen't matter if you fill through the oil fill or exhaust port. Requires a 10-30 second break in period prior to first use... Anytime you remove the oil fill cap, always inspect the o-ring as mine fell off the cap and luckily I happened to notice. Also, double check drain plug prior to first oil filling out of box as mine seeped a little oil, don't over tighten, just snug as you may potentially damage o-ring... The pump comes with a hex drain bolt unlike a knurled bolt shown in image... Pump will pull a vacuum within 20 -30 minutes on a/c auto systems. After 30 minutes of operation, the unit is safe to touch ( lukewarm ). I was initially concerned with the plastic handle but it has a solid, sturdy feel. The pump will occasionally mist oil out the exhaust port, more so at vacuum start up or if overfilled. As for oil usage, I performed 5 30 minute vacuums w/o any noticeable oil loss. As for loudness, it relatively quiet and safe for indoor use, minus occasional oil mist... I've only pulled a vacuum on five auto 134a a/c systems since purchasing, 3 of these jobs were compressor burnout replacements while the other 2 were refrigerant loss / leak repairs and the oil has just now shown signs of needing to be replaced. I know every manufacturer recommends you change the oil after every use, they also recommend you use only thier brand oil. As I was saying, during the 5th vacuum I pulled I noted the oil was getting milky during vacuum operation upon visual inspection through the sight glass, although the oil was clear after shutdown. Time to change the oil as that is where all the moisture remains that doesn't get boiled off during vacuum, while the frequency of oil change intervals is debatable.... the oil will need to be changed when showing signs of cloudiness in color, poor performance or you can routinely change after every use as recommended should that be the maintenance interval you prefer, no doubt the pump will pull a quicker vacuum with fresh oil.. The pump comes with a bottle of oil that is enough for 1 1/2 fill ups.... Hint: Buy a pump oil that contains no additives, as additives breakdown and contaminate quicker when mixed with moisture. Also, ensure that you install the dust cap on the pumps fitting while not in use to keep moisture out as failure to do so will shorten the oil life span One thing I've noticed is this pump pulls a vacuum pretty quick for its size, you can hear the change in the pump when the pump has pulled most of hte moisture out of the system. On the 3 a/c systems where I replaced the receiver driers and compressors, the pump pulled a vacuum down to 29 µm and 28 µm on the systems w/o drier / compressor replacement. See pics below of vacuum in progress, oil fill port, sight glass and drain plug..... I would have loved to have bought a higher end pump but funds were tight. None the less, I am very satisfied with my purchase, very smooth transaction...The only shortcoming I found.... Made in China Update: Performed 17 auto a/c vacuums since purchase, no complaints .... ## Frequently Bought Together - Robinair (15310) VacuMaster Single Stage Vacuum Pump - Single-Stage, 3 CFM Silver - TSI Supercool Vacuum Pump Oil, Synthetic, 32 Oz., Clear (V32) - Simple Woodturning Tools - Vacuum Manifold Kit Connects Vacuum Supply to Chuck on Wood Turning Lathe --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/82514893-15310-vacumaster-single-stage-vacuum-pump-single-stage-3-cfm](https://www.desertcart.com.ar/products/82514893-15310-vacumaster-single-stage-vacuum-pump-single-stage-3-cfm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-13*
