NAVAC HVAC Vacuum Pump - Reliable Dual-Stage AC Motor Pump with Lightweight Design for Residential & Commercial Use - Ideal for Evacuation of HVAC Equipment - 15 Microns - Pro Series - 7 CFM Flow Rate

This pump is a huge upgrade over the Robinair 3cfm pump that I have been using for 13 years. You get the three different size fittings on this machine, 1/4, 3/8 and 1/2.Came with enough oil to get you started. You should purchase more oil as you will be replacing it every so often (depending on how often you use this pump), but could be as often as every month.Nice large sight glass, you're able to see the level at a quick glance as well as the condition of the oil.

Pulls a deep vacuum very fast, even with a small hose.

I have been using this pump for a year with my freeze dryer (approx 100 hours). I get good vacuum and all works as expected. It runs for about 12 hours each time I use it.

There are a lot of different options for vacuum pumps. I liked this one because of the quiet, easy and efficient use of this pump. Highly recommend this pump. I use this on a daily basis. Not a complaint at all.

The vacuum pump part of it is amazing all the plastic on it is cheaply builtPulls a 5 ton with 60ft of used line through a 1/2" hose and puller to 300 in 20 minutes good value and it's A2L

With the appion hoses and speed set up, this vacuum pump work great! Pulls deep vacuum in a short amount of time, and is very quiet. Very happy with the vacuum pump

Pump hasn't lasted 60 days I have a meter to test how deep of a vacuum and how quickly out of the box was great after minimal use now won’t pull down to deep vacuum like it did day one. Save your money this is not a quality part granted it’s cheaper but 60 days and it’s already worn out.

Haven’t had many Navac tools but they seem decent. Used vacuum pump next day after arrival.
