Ultra‑Precision Mobile Oil Purifier, Achieve NAS4‑6 Oil Cleanness For Servo Hydraulic System
Product Spotlights
Ultra‑precision oil purifier is mobile six‑stage gradient pressure‑driven filtration equipment for scenarios requiring extremely high oil cleanliness. Ordinary mobile oil filter carts can only reach NAS6‑12 grade. For high‑end servo hydraulic systems, precision test‑benches and military‑related equipment, even tiny sub‑micron particles will cause valve jamming, component wear and performance degradation. This ultra‑precision purifier solves this critical pain point.
Contaminated oil is delivered by low‑pulse gear pump to reduce fluid turbulence which may re‑generate fine particles. Heavy‑duty pre‑filter installed at suction side captures large‑size impurities and protects pump. Oil flows sequentially through six‑stage progressive filter chambers, filter density increases step‑by‑step to trap coarse particles first and then sub‑micron fine debris and oxidation colloid. All internal pipelines are thoroughly cleaned during manufacturing to eliminate secondary pollution risk. Treated oil stably reaches NAS4‑6 cleanliness grade. Optional coalescing‑dehydration module removes free water from oil.
High‑precision differential‑pressure gauge is mounted on housing for accurate filter‑clogging judgement. Overflow relief valve and thermal relay provide double‑protection against motor over‑pressure and overload burnout. Quick‑open filter housing simplifies cartridge inspection and replacement without complex disassembly. Universal brake casters support flexible movement between oil drum, servo hydraulic station and test equipment.
Standard housing adopts thickened anti‑corrosion spray‑coated carbon‑steel. 304 stainless‑steel housing is available for strict working‑environment. It supports oil filling refilling, oil‑drum circulating filtration and servo‑system bypass continuous on‑line purification.
It is widely applied in high‑end servo hydraulic stations, ultra‑precision machine tools, industrial laboratories and military‑support oil‑maintenance projects. Every unit will pass pressure tightness and oil‑cleanness inspection before shipment. Custom flow‑rate and filtration precision are supported.
