I truly love this vacuum pump, I work on small residential hvac equipment and this has worked very well,I have upgraded the 1/4” flare connection to a 3/8 and am using a vacuum manifold with a shut-off. And the makita 18v batteries work great just make sure you order the charger as well.I ordered a storage bag with hard bottom that holes the pump, batteries,charger and hoses. Just grab the bag and your ready to go.I recommend this pump and be ordering a second one for my other truck.

This thing is so light and easy to carry on to the roof of commercial buildings. I no longer have to wire in an outlet to get power on the rooftops. And it actually works fast. The only complaint I have is the service port is so close to the handle, that my low loss fittings will not screw on unless I loosen the handle and turn it sideways. No big deal though. I can either add an adaptor, or just keep turning the handle. Either way, buy it! You will not regret this purchase. I don't. I've been in the Refrigeration business 25 years. Everything is on the roof of these restaurants.

I purchaed this as I am a mobile auto repair technician. Unfortunetly it didn't last. I used 1 time and it worked great. Went to use it today and the motor smells burnt, and it beeps and shuts off. I was originally planning on keeping it, but this stinks. Hopefully Amazon can make this right

Made my life very easy, love it every A/C technician dream tools

The microns wouldn’t go below 750 on a 2 ton split system. Also ran about 20 mins and got extremely hot. Going to try a again tomorrow wish me luck.

I like the product, but it doesn't come with an instruction manual, which makes me wonder how it works. The case I received has oil leaking out. The model does not seem brand new, it may be a second-hand product.

Very light and fast vacuum works extremely well, I'm impressed with this very portable vacum highly recommended i did more than 5 complete vacuum on a single battery

I've used this to pull a vacuum on a 5 ton rooftop unit. It didn't take long and it still had battery enough for a couple of compressor changes on small coolers. If you do a lot of rooftop work this is well worth the money.
