The FilterVac stationary, portable and mobile High Vacuum Transformer Oil Purifiers (Model VPH) are used for transformer oil degasification, dehydration, filtration and optional de-acidification. The VPH works equally as well with other electrical insulating liquids such as silicone fluids. The VPH Process is able to increase and maintain the oil’s dielectric strength by removing free and soluble water, free and dissolved gases and particulate matter. The standard Transformer Oil Purifier is designed for processing oil in workshops, storage tanks or directly in energized or de-energized transformers.FilterVac offers a variety of Transformer Oil Purifier flow rates and options to suit every customer’s requirements. Optional features offered are conventional Fuller’s Earth filter(s) or column(s) for acidity and colour rectification.

In addition, FilterVac offers Transformer Oil Purifiers to treat cable oils (Model VPH-C) including many other applications outside of the electrical industry. For example, electronic and radar equipment, vacuum pump sealing oils, brake fluid and refrigeration oils.

FilterVac manufactures customized Transformer Oil Purifier to meet your specific transformer oil purification and transformer oil filtration needs.

FilterVac offers many options with the VPH system including operation on Live Transformers. Utilizing the LM Option (Level Monitoring), the VPH Transformer Oil Purifier does not alter oil level in transformer. This avoids potential oil drainage from the transformer while it is energized. FilterVac supply a Valve Assembly Box that contains automatic valves and air eliminators. This Portable Valve Box Assembly is installed adjacent to the transformer, connected to the transformer inlet and outlet as well as to the VPH system inlet and outlet hoses.
