Description of the RFX

The RFX is an abbreviation of REDucer of Fluid OXidation and is a hydraulic powered
degassing and dewatering unit. The RFX demands only small space, has low power
consumption and low weight. The RFX is made for permanent installations in mobile
machines as well as in stationary systems, where the oil condition is of great concern.
