OIL DEHYDRATION EQUIPMENT FOR HYDRAULIC & LUBE
Vacuum Dehydration Oil Purification Systems for Sale
Precision Filtration Products supplies industrial vacuum dehydrators from 1–100 GPM for removing free, emulsified and dissolved water from hydraulic oil, turbine oil, lube oil, gear oil and other industrial fluids. Systems are available in standard and explosion-proof configurations and can achieve water concentrations as low as 20 PPM in multi-pass operation.
Our superior engineered design features maximize the water extraction rates from your oil. Utilizing top-quality components and workmanship ensures years of maintenance-free operation and performance.
Our Vacuum Dehydrator Oil Purification Systems (VDOPS) have the ability to develop high-vacuum and high-flow speed for dissolved water and gas removal. The VDOPS has a high negative-head capacity and is flexible with design dimensions and process arrangement. We will listen to your needs, then customize a vacuum dehydration system to your specific application.
It has been well documented that there are harmful effects to the components on rotating equipment caused by particulate and moisture contamination in hydraulic and lubrication oils. End-users can dramatically increase the life of the critical wear components and in-turn minimize downtime and maximize profitability.

FAQ’s
What is a vacuum dehydrator used for?
A vacuum dehydrator is used to remove water from industrial oil. These systems are commonly used for hydraulic oil, lube oil, turbine oil, gear oil, and other compatible fluids where water contamination can affect performance, reliability, and equipment life.
How does a vacuum dehydrator remove water from oil?
A vacuum dehydrator removes water by using heat, vacuum, and controlled oil flow. Under vacuum conditions, water vaporizes at a lower temperature, allowing moisture to be separated from the oil without exposing the fluid to excessive heat.
What types of water can a vacuum dehydrator remove?
Our vacuum dehydrators are designed to remove free, emulsified, and dissolved water from oil. This makes them useful for applications where standard filtration, settling, or draining cannot fully remove moisture from the fluid.
Can a vacuum dehydrator remove water from hydraulic oil?
Yes. Our vacuum dehydrators are commonly used to remove water from hydraulic oil, especially when the oil appears cloudy or milky, or when oil analysis shows elevated water content.
When should oil be dehydrated instead of replaced?
Oil dehydration may be practical when the primary issue is water contamination and the oil is otherwise suitable for continued use. If the oil is severely oxidized, chemically degraded, or contaminated beyond recovery, oil replacement may be required.
How quickly can PFP put a vacuum dehydrator on-site?
Lead times for a permanent vacuum dehydrator system depend on the required flow rate, system configuration, fluid type, available inventory, and project requirements. PFP can help review your application and determine the best equipment option for your oil purification needs.
For urgent water contamination events, maintenance outages, or short-term oil dehydration projects, a vacuum dehydrator rental may be the fastest option. View our rental options or contact PFP with your applications details and jobsite location so our team can review availability.
