How does rotary vane vacuum pump work?

vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guerick. Vacuum pumps have been used in different industries, and different types of vacuum pumps have been developed. Rotary vane vacuum pumps are the most common. The following animation demonstrates how a rotary vane pump works.

Testimonial

“The vacuum worked good on my 2005 Ford Explorer. I didn’t have to add the full bottle of oil to the pump. Pulled a vacuum twice so far one for 30 and one for 2 hours. 3.5 CFM is all that was needed for my SUV.”

Todd Butler

“I used this to pull a deep vaccum on my home air conditioning system when the compressor went out. It did a great job, it wasn’t very fast but perfect for what I needed especially for the price. Definitely a good quality pump for the money.”
