Filson Vacuum Dehydrators(VAD) are designed to remove as much as 90-95% of all dissolved water, as well as 100% free and emulsified water from petroleum and synthetic-based fluids, resulting in levels of water often below 10-20 ppm. Filson portable vacuum dehydrator can remove 100% of free gases and at least 90% of dissolved gases, as in transformer oil purifier and lube oil purifier.
- Highly efficient in air and gas filtration
- Higher water removal efficiency—as low as 20 ppm
- Dimension and arrangement design flexibility
- Heaters to increase dewatering performance
- Easy handling and automatic supervision using the PLC control

Filson Vacuum Dehydration Oil Purification Systems
In order to safely monitor oil dehydration system and maintain absolute fluid cleanliness, our vacuum dehydrators are equipped with automatic PLC controls and series of electrically controlled switches that will shut down the vacuum oil purifier if the operating parameters go beyond the normal limits. With the maximum flow rate of 200 l/min, vacuum dehydrator oil purification systems come in a number of different sizes and flexible designs with three-stage filtration, but they all have the same basic working principle.
Principles of Filson Vacuum Dehydrator Operation
Contaminated oil enters the oil vacuum system and passes through heaters that raise its temperature to about 60°C. It is a critical procedure for cold or high viscosity oils. Oil is then dispersed to a distillation column where it is exposed to the vacuum. It is degassed and dehydrated then pumped out through the vacuum chamber’s bottom section. The oil passes through a hydraulic pump into the particulate removal filter. The final product is clean and dry oil re-enters the reservoir or system via the outlet port.
