Mastercool 6 CFM Single Stage Vacuum Pump 90066-B

So far so good! It is working great!!!

This is the exact same item as the one another brand uses. Begins with snap, and ends in on. Save them dollars.

I have been using these pumps for many years, they work great to get down to a deep vacuum. I use multiple of these vacuums with 1/2 vacuum hoses on one system. Pulls down to 500 microns before you know it. I use mine for a year and then retire them with a new one, and at the price point it is worth it. The pumps still work after a year and you can flip the apex seals in the pump to get longer life out of them.

Good product that can get the job done. Shipped with less oil than what was needed but I had some in storage. I wouldn't say its quiet but it to offensive or anything.

Nice light weight pump for the money. Pumps a system down pretty fast. The only thing I don’t like is the fact that this pump is made with cheap materials. You can’t throw it around like the more sturdy pumps. The metal cover over the motor fan is vey thin and damages easily as mine has done twice. It should be kept in a box in between uses or when being transported. I like the fact that it is light and pumps a system down quickly and didn’t cost a lot. Time will tell if it was a real bargain. It has performed well the 20 times I have used it.

Works fine

We purchased this pump to run our milking machine for our cow. It is not heavy duty like the pumps my husband uses in his HVAC job, but the price tag was much, much less. It did the job we needed it to do. We only used it a few months before drying our cow off, but it will be put back to work soon after calving season. I will update this review if needed.

Bought this after trying to do lots of research it seemed promising but I got it today and straight out of the box doesn’t even turn on. Defective…. Really frustrating as I needed this today for a job I was working in.
