Portable Oil Filter - MXP5E-1

Portable Oil Filter MXP5E - Data Sheet #1996

Superdri® Handcart Filter System


The MXP5E comes with all the features needed for proper use of Velcon Superdri® Cartridges for dissolved water removal from transformer oil. Parallel flow through the two filter housings assures the proper flow rate through each SD-718 Superdri® cartridge. The unit is also valved so that series flow is possible for non-dissolved water oil handling applications, such as removal of dirt and free water. Use FO filter cartridges in the first housing to remove dirt particles. An Aquacon® cartridge in the second stage removes free water. The flowmeter/totalizer feature allows the user to calculate the approximate lifetime of the Superdri® cartridges without an on-line moisture monitor. For dissolved water removal from transformer oil, the MXP5E is an economical alternative to more costly heat and vacuum systems.


Vacuum-type LTCs To use the MXP5E on energized vacuum-type LTCs, it is important to have a means for removing air from the system’s filters, piping and hoses before circulating the oil. Velcon recommends adding optional vacuum pump (PN 103Y026) when ordering the MXP5E for this application.
