AquaKV-Pak® depth filter cartridges were developed specifically for the retention of water contamination in transformer and turbine lube oils in addition to the retention of particulate down to sub-micronic levels. Added to the retention capabilities of the Disc-Pak® is an enhanced capacity for the retention of free and dissolved water. Particle retention does not affect water-holding capacity, which has been documented at up to 120 oz. per 9 cell Pak. The AquaKv-Paks® can recondition your dielectric fluids to meet or exceed ASTM and manufacturer’s standards.
