Review on 🔧 CPS Pro Set VP6S Premium Series 6 CFM Single-Stage Vacuum Pump with Gas Ballast Valve, Dual Voltage 115 / 230V by Loren Jacobson

I have had this pump for several years. This product works great until winter. When the ambient temperature is low, this product will not work, it will not turn on. I called CPS and they told me they would offer a "cold weather kit". So you have to buy something extra to make their product work. We're not talking about winters in Maine, I live in Virginia and every winter this pump fails and our company has to use a different pump. I regret the purchase and definitely do not recommend it to anyone. There are other vacuum pumps for the same money or less that outperform this pump. When it gets 40 outside, this pump is terrible. The only reason why it gets stars is that it works well when it is warm and can usually be used for 3 seasons over several years.
