Transformer Oil Filtration Machine




VFD series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. VFD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.



1.  Effective and efficient Dehydration (Degassing) System


2.  High precision Filtering System


3.  Powerful double stages vacuum system


4.  Electrical apparatus controlling System


5.  High quality components


6.  Diverse design in the structures and functions. The machine is available in mobile or stationary options. Various sizes and configurations (alloy shield) available.


Available Style


Fixing type, mobile type with four wheels and mobile type with trailer


Normal appearance type, shelf-covering type and explosion-proof type


Available in different color.


VFD Main Additional Configuration


1. Foam Level Detector

When there is foam in the tank and foam reaches a certain level (resetable), a signal will be sent to the magnetic valve, the magnetic valve will automatically shut on. The foam will be removed quickly. After removing foam, the magnetic valve will shut off.


2. Digital Vacuum Gauge (Pirani gauge)


Measure Scope: 1.0×105 – 1.0×10-1 Pa


Display Type: Digital


Accuracy: ±1.0%


3. Digital Hygrometer(water or moisture in oil tester)


On-line type


Measure Scope: 0—100 PPM


Display Type: Digital


Output Signal: one is PPM, the other is temperature.


4. Digital Flow Meter


Display Type: LCD


Mode: 1) accumulative total value 2) online flow value 3) accumulative total value for each time (reset adjustment)


5. Breakdown Voltage Tester


Printer output


Input voltage: AC 220v


Output voltage: AC 0—80kv


Voltage rising rate: 2kv/s±10%


Test precision: 1.0grade


Test times: 1---9, stirring time: 0---99seconds, stewing time: 0---9 minutes 59 seconds


6. Structure and Appearance


1) Single axle trailer: mounted on chassis with 2 pneumatic tires, 1 pre-leg; covered steel shield, air brake system, hand brake, rear lights, tow-eye etc.
