hilmor Vacuum Pump 3 CFM, 1947970

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.

Keep up on your oil changes and make sure that your voltage is correct, it will always treat you well.

The 9cfm is a beast! It pulls a good low micron vacuum in no time. If anything it's over built which is great if you want a hard working piece that will last years. One tip, buy the carry strap. This thing is heavy but the hilmore strap is amazingly comfortable. I bring this thing up 3 story access ladders no problem and no sore sholder. Great vacuum pump!UPDATE: Still going strong. After a year and a half and a 100 installs this thing is bullitproof. With clean oil it works like the day I got it. With a 1/2" hose it pulls sub 100 microns in no time. It's the fastest pump in the company beating out the NAVEC guys who paid more. Love it.

The machine starts to leak once up to operating temperature.The filler cap leaks, made of plastic and threads into a casted base.The threads are almost nonexistent in the casted base.Oil drain plug leaks not matter how tight it is.The filler cap has a rubber molded cover that basically falls apart once pump gets hot.Would like to get my money back.

This has made my job much easier and quicker

First use today. Using it to evacuate a pressure vessel with wood immersed in oil(the final finish). Lovely foaming bubbles. Seems like it works fine. Quite quiet. I think it will turn out to be a quality tool. More in a couple of years.

Company won’t provide tools and said I need to provide everything for installs. Since it was coming out of my pocket, I wanted to buy something good that will last. I’ve been using this daily for a few weeks now and I absolutely love it. Combined with my dedicated Appion vacuum set up, most residential systems only take a few minutes to pull down to 300 or less. A faster pull down means I get to watch my decay longer without losing time. This is the vacuum pump to get if you need quality and value for your money

This thing is the favorite of all my guys. They love to use it. It is light weight, fast and oil changes are pretty quick and it uses so little oil compared to some of the other pumps we have. Highly suggest it.
