Review on 💪 Powerful and Reliable: MASTERCOOL 6 CFM Single Stage Vacuum Pump (Model 90066-B) by Tony Weber

I've used these pumps for years, they work great at creating deep vacuums. I use several of these with 1/2 vacuum hoses in the same system. Pulls up to 500 microns before you know it. I use mine for a year then throw them away with new ones and for the price it's worth it. The pumps are still running after a year and you can reverse the top seals in the pump to extend its life.
