The Schroeder Industries North American Vacuum Dehydrator uses vacuum dehydrating technology to remove both free and dissolved water, and gases, from oil. In addition to water and gas, the North American Vacuum Dehydrator (NAV) also removes solid contaminants with filtration ranges from 1 - 40 micron standard options. The NAV has a flow volume of 30 gpm and is designed for use with larger applications, such as the conditioning of oil in larger hydraulic and lube reservoirs.
