Our second choice is another decent choice for any garage or air conditioning technician. But first, it is important to note that this machine is a single stage vacuum pump. Our first choice is at what stage but that does not mean this single stage vacuum pump is not any better. In contrast, it is quite popular, and that says a lot. Don't you think so?
The vacuum pump comes with a robust endurable cast aluminum housing that protects the interior engine and mechanics from any damage. And despite the sturdy construction, the vacuum pump is lightweight. Nothing to worry about in that regard!

Decision
We were surprised to see some of the complaints from the users as we completely disagree with those. It’s true that it has a few shortcomings as it happens in case of other quality products, but they are very much nominal compared to the excellent features it has and the facilities it provides.
