Elitech SVP-7 7 CFM 2-Stage HVAC Vacuum Pump with Intelligent App Control, Touch Screen & Leak Detection - Perfect for AC Repair, Refrigeration Service and Automotive HVAC Maintenance

This replaces a 6 cfm that I thought was pretty good. This one is awesome . I can't imagine why you wouldn't love it. I milk 2 goats (3 next year) one at a time. But, I could definitely milk 2 goats simultaneously. Building a new milk stand!Para hacer vacío en una unidad de HVacScreen work great vacuum works great constantly leaks where the micron gauge hooks to the pump great tool till you have to fix over and over about 3 months use installs and repairsReaches less than 500 micron in less than 15mins sometimes though you will wait a good hour to achieve 500 micron or less…..but be rest assure anything 1000-1500 micron is achieved very quickly ……and shows u the vacuum graph too. Great vacuum with BluetoothGreat pump but..... micron gauge doesn't work properly besides that its a great pump. Tried contacting manufacturer gave me some bow about how the micron gauge works on this unit. Great idea but in action still needed to buy a micron gauge in which I was trying to avoid purchasing. It does detect a leak though. Great function. But pump said 400 microns and external micron gauge said 1200 which indicated a leak in the system. Pump did detect a leak but microns didn't even came close to the external micron gauge. In my understanding any thing isn't a leak. I am still confused. But other then that it is a great pumpI've used small single and 2-stage vacuum pumps for years to pull down vacuum bags for composite parts, and it was time for yet another vacuum pump. I was ready to pay more for a more serious pump, when I came across this gem. The pump's performance specs seemed perfect, and the added digital readout and bluetooth app seemed very useful.I've used the pump about 30 times, mostly to evacuate air from a 2 gallon outgassing chamber, and for a couple of vacuum bagging projects. The pump performs extremely well, pulling down vacuum faster and deeper than my other small pumps. The fittings on the pump were the same as my other pumps. The build quality of the pump seems better than most.What amazes me is the LCD display actually shows the pressure at the vacuum inlet, and it can also graph the pressure change over time. It also shows both the pump and the oil temperatures, and sounds an alarm (?) if they reach a preset maximum. It has many other features that I haven't even used yet. The bluetooth apps works great, and I can view and adjust the vacuum set points remotely, and probably do a lot more. Because of the robust display and information on the touchscreen, I will have trouble going back to using "dumb" vacuum pumps.My old vacuum pump stopped working after 20 years got this one for a replacment so far I love it very easy to use works fast and micons are shown right on the pump so I no longer have to use a external gadge wish there was a gard over the screen but love the pump hope it last as long as the firstI can pull it to under 300 microns in less then 10 minutes! Real time saver! It also show if there is a possible leak in the system!
