LV(lube oil purifier,oil filtration,oil purification,oil filtering,oil recycling,oil treatment,oil regeneration,oil reprocessing,oil filters)series is suitable especially for purifying and restoring hydraulic oil, machine oil, coolant oil and other lubrication oil. The most breakdown of machinery which has lubrication oil system results from contaminated lubrication in which has water, gas, impurities etc. LV series can rapidly remove water, gas, particulate matters and impurities from lubrication oil and improve properties of lubricating oil so as to greatly extend lifetime of machinery which has lubrication system
