Solid Pump!
Style: 3 CFM
Nicely built pump with good quality feeling. Pulled down to 25 microns for my two-zone mini split system in an hour or so with 100LF of lineset. I was on the fence to go with a bigger pump based on some other reviews and info I read but I’m glad I chose the 3CFM pump and had no issues. I used a Appion hose with 3/8” and 1/4” fittings to a JB core removal tool with COS digi gauge.

A micron gauge would make it a lot better and should be included
Style: 3 CFM
This pump works really well. A micron gauge would make it a lot better and should be included. It's very quiet for a vacuum pump. It's heavy duty and the carrying strap is nice too. Having two ports on top makes it easier to hook up different size hoses. Looking forward to adding items to make it even better.

Internal Filter, Gas Ballast, and Large Oil Input Hole Make This A Contender
Style: 3 CFM
Now that Spring/Summer is coming up, it is a perfect time for some A/C repair, refilling. Going into this I have never used a hilmor pump before, nor heard of the brand. After using it, however, I can say I'm impressed enough overall and can say the differences between this one and my existing one (bought at a certain well known discount parts store) are enough to warrant a price hike. Firstly, this doesn't really need to be said if you are looking at this product, however this is for (at least for me) evacuating a car A/C system or checking for leaks/refilling. More specifically, if you need to install a new compressor, or want to do a thorough refill, use this pump along with a A/C hose kit. The pump puts a vacuum on the system so you can read A/C gauges to check for leaks and/or to get all the moisture out of the system. Usually you are looking for around a steady 28/29 reading on the A/C gauge before/after closing the valve on the low/high pressure sides to eliminate the possibility of leaks. For my purposes, this performed well and as intended. The oil level see-through lens on the front is typical on about any pump. The oil load hold is much bigger than my current pump, and is big enough to use a normal funnel. Love the size and location of it (it's near the end of the pump). The cap to the oil input valve is plastic, where I would prefer it was metal, however I wouldn't expect this big of a cap to be metal. Draining is the same as my other ones where there is a drain plug on the bottom. I always change my oil out after every evacuation, and through two evacuations with this, the oil wasn't dirty coming out (nor did I really expect any different) and was easy. Sound level was about the same as my other pump if maybe a tad bit quieter. Pump weighs around 20lbs (~9kg) and is made in China with a 2-year warranty. One very strong plus to this pump is: 1. It comes with an internal filter to keep debris from the pump motor and 2. The gas ballast to let any existing moisture from the oil 'seep' out if it is there. These all tell me that this pump aims to prolong the oil you use in it. Usually we replace the oil after every change to eliminate the possibility of too much moisture in the oil and to keep the pump working longer. Since the internal filter eliminates any possible debris, and the ballast may help eliminate excess moisture, then you may realistically be able to go 2-3 evacuations without an oil change. I wouldn't test the latter however, knowing that these prolonging functions are built-in, it tells me this is probably (hopefully) a long lasting pump. ------------------------- A high quality vacuum pump that works for a typical car A/C hose line system that adds a bit of 'life-prolonging' additions by way of an internal filter and a gas ballast for excess moisture escape. For the potential of a longer-living pump than other manufacturers, the price premium may be warranted. However, more uses are needed to see the actual life expectancy.

Top Quality Equipment and Tools.
Style: 3 CFM
I like to keep everything cleaned up and on top of things on the job so that when it comes time to evacuate the system I can focus on any leaks that might be present or if everything is going good that day sit back and relax a bit before it time to start charging which is my least favorite part of the job. A good vacuum pump makes this faster and less complicated, especially if you do have leaks to find. i've heard of how great Hilmor products are but have never experienced them prior to this. I must say they deserve their great reputation. They remind me of Festool products which are also top quality. You can usually tell a very well made piece of equipment when you see one, and hopefully it operates the same as it looks. In this case it absolutely does. It is powerful, quiet and precise. It draws down the lines fast. The pump is smooth operating. I like how compact, simple and well designed it really is. The included shoulder strap is perfect for transporting it because you can be carrying it along with your other tools all at once. A mechanics backpack ( I like the Veto Pro Pack) and this pairs up nicely. I would like to get some Hilmor accessories to go with it. Their 4 valve aluminum manifold looks great. It is suppose to have a true 3/8" bore thru out for faster pulls. HIlmor also recommends using their hoses as well. The valve core removal tool has a magnet on the back of the plunger to keep the Schrader valve core from falling on the ground, getting lost in the grass or getting dirt all over it. Yes I do want one. I also want to get the swaging kit. I think this is one of those brands that once you get one of their tools you want to start switching out all your stuff. These are all "top shelf" products with a premium price, but I do feel that the extra cost equals faster and more efficient work flows, longer lasting tools, and a more pleasurable job experience. There are always variables to deal with on every job, and I always look to reduce the number of them. Having dependable tools and equipment can remove quite a few of them. This is what I look for in a 5 star rating. Top quality.
