HYDAC Vacuum Dehydrators
HYDAC FAM 25 Oil Purifier
The HYDAC FAM 25 Oil Purifier operates on the principle of vacuum dewatering to eliminate free and dissolved water as well as free and dissolved gases from hydraulic and lubrication fluids. Since it uses HYDAC offline filter element technology with its high contamination retention capacity and filtration efficiency, the unit is extremely economical. All units have an AquaSensor AS1000 for continuous monitoring of the water content and for controlling the unit. To increase the dewatering capacity, for high viscosity fluids or low fluid temperatures, an integrated heater is provided.
Benefits of the HYDAC FAM 25 Oil Purifier
- Longer oil change intervals
- Improved component service life
- Greater machine availability
- Reduction in the Life Cycle Cost
