What is a Vacuum Dehydrator? - Hy-Pro Filtration

How does it work? In a nutshell, a vacuum dehydrator heats the oil (130-160F), if necessary, and draws a vacuum (18-27Hg) on the oil. Raising the temperature while drawing a vacuum causes water to flash to steam at a temperature low enough not to cause thermal breakdown of the oil. At sea level, water flashes to steam at 212F.

Understanding Vacuum and Vacuum Measurement

very close together, so the collisions are very short. The distance between molecules is a function of pressure and is known as the mean free path (MFP). 3 As the chamber is pumped down into vacuum and molecules are removed, the MFP becomes greater and greater. As pressure decreases in a chamber, fewer molecules are
