CPS VP4D Vacuum Pump| High-Performance 4 CFM Dual Stage | Compact Design for HVAC/R Applications | Durable; Lightweight & Quiet | Perfect for Refrigeration and AC Repair

I have had this pump for about 2 months. I used it to pump down my mini split 2 times now. The last time I left it run over night and pumped the entire system down to 180 microns. Good little pump. The pump seems pretty sturdy and appears well built. Has multiple ports you can use at the same time reducing pump down time. I recommend this pump and would buy again from this seller. Great product and great service.

A little on the pricey side but worth the money. I do not have an accurate way of testing the vacuum that it can pull but if you get your finger wet and put it over the large opening, you can feel the water boil off in the low vacuum and your finger gets very cold! It definitely is a high quality pump and has not failed on me yet! Evacuates very quickly!

check valve must be broken, pump fills the lines with oil and doesn't pull a vacuum.

Nice pump

This pump sucks. BIG time! It's very well made and quickly builds a vacuum to evacuate A/C systems. It's way more than I needed for occasional use at home, but it never hurts to have awesome tools when you want to do a job!

This pump arrived on time and was well packed for shipping. It is not overly noisy and pulled a great vacuum easily. Appears to be well built and hopefully will last many years with proper care.

shipped in original box that was open ,although everything was still sealed on the inside and looked new,Fast shipping and great price.Put the pump to use the first day on multiple vehicles and it works great would buy again.

Good product and very reliable
