    Does exactly what it’s supposed to do
    I work in commercial HVAC/R and this is the vacuum pump I have been using. READ THE MANUAL. It’s a good pump. I can pull sub 500 microns pretty quickly. Rarely, is it the pumps fault if it does not. Check your welds, hose connections, and such. I’ve had a couple of times where it just was not pulling vacuum quickly. Those times, the issues have been the oil. Which changes quickly and easily. For the price point, you won’t find as reliable a pump. My coworker got the smaller 5 cfm Robinair pump. He likes his. My 8 cfm pulls down much faster. The trade off is my pump is heavy. I typically have to pull it up on rooftops by a rope. The little rubber feet on my unit also fell off in the first few weeks of using the pump. To me, it’s not a big deal. But again, the price is tough to beat. For less than $400, this unit is outperforming units that cost twice that. I use it in conjunction with the Testo wireless vacuum microns gauge. I use these units almost daily. I provided a few photos of the pump on the job. Surprisingly, this pump is not very noisy.
