Vacuum Oil Purifier with Complete Accessories The Vacuum Oil Purifier is a high-performance industrial oil purification system designed to remove solid particles, moisture, dissolved water, and air from lubricating oil, hydraulic oil, transformer oil, and other industrial fluids. Supplied with complete accessories, this purification unit provides an efficient solution for oil maintenance, oil regeneration, and contamination control in demanding industrial applications. With a processing capacity of 50 liters per minute, it is suitable for workshops, equipment maintenance centers, power plants, hydraulic systems, and other facilities that require reliable oil purification. Technical Specifications Product Type Vacuum Oil Purifier Accessories Complete Accessories Included Flow Rate 50 L/min Working Pressure 0.6 MPa Vacuum Level ≤ -0.095 MPa Residual Water Content 5–10 ppm Residual Air Content ≤ 0.2% First-Stage Filtration 100 μm Second-Stage Filtration 10–20 μm Third-Stage Filtration 1–3 μm Voltage 380 V AC Frequency 50 Hz Phase Three Phase Motor Power 36 kW Heating Power 24 kW Control System PLC Control Efficient Vacuum Dehydration and Degassing The purifier operates with a vacuum level of ≤ -0.095 MPa, creating an effective environment for removing moisture and air from contaminated oil. After treatment, the residual water content can be reduced to approximately 5–10 ppm, while the residual air content is controlled to ≤ 0.2%. This helps improve oil cleanliness and reduce the negative effects of moisture and air on lubrication performance, hydraulic components, pumps, valves, bearings, and other critical equipment. Three-Stage Precision Filtration The Vacuum Oil Purifier uses a three-stage filtration process for progressive contaminant removal. The first stage uses a 100-micron filter to capture larger solid particles and protect the downstream filtration system. The second stage provides 10–20 micron filtration for finer contamination control. The third stage uses a high-precision 1–3 micron filter to remove very small particles and achieve a higher level of oil cleanliness. This multi-stage design supports stable purification performance and helps protect critical components from particulate contamination. Powerful Heating and High Processing Capacity Equipped with a 24 kW heating system, the purifier provides effective heating during the oil treatment process. Controlled heating helps improve moisture separation and supports efficient vacuum purification. With a 50 L/min flow rate and 0.6 MPa working pressure, the system is designed for high-capacity industrial oil purification and continuous maintenance applications. PLC Automatic Control The system features PLC control for organized and automated operation. Its electrical configuration is 380 V AC, 50 Hz, three phase, with a 36 kW motor. PLC-based operation helps simplify system management, improve process consistency, and reduce the need for frequent manual adjustments during purification. ...

A properly matched oil filter helps remove contaminants carried by engine oil. This supports cleaner oil circulation and helps reduce the risk of abrasive particles moving through engine lubrication passages. Filter performance depends on the filter design, oil conditions, and the service requirements of the engine.
The broad cross-reference list makes the P550779 a useful item for professional parts lookup. Buyers can compare familiar numbers from several brands when reviewing inventory, answering customer inquiries, and preparing maintenance orders. Always verify compatibility before treating a cross-reference as a confirmed interchange.
With a minimum order quantity of 60 pieces, this product is intended for B2B sourcing rather than single-unit consumer purchases. Retailers, filter shops, wholesalers, and service providers can request quotations for their expected quantities and discuss packing requirements before placing an order.
For buyers exploring a Custom Made Oil Filter program, China Everlasting Parts can discuss OEM/ODM requirements and product sourcing needs. Any custom specification, labeling, packaging, or production arrangement must be confirmed with the sales team before it is considered available.
A Diesel Engine Oil Filter or Industrial Engine Oil Filter must match the relevant application, thread, seal, flow, and filtration requirements. P550779 is a candidate for compatible applications, but the exact engine model and maintenance specification should be checked before use. This helps reduce ordering errors and unnecessary returns.
Professional buyers may investigate P550779 for compatible diesel engines, industrial engines, equipment maintenance programs, and aftermarket parts inventories where the listed reference numbers are applicable. The cross-reference list includes brands associated with agricultural, industrial, construction, and engine-related equipment. These references do not mean that every machine from a listed brand uses this filter.
Before ordering, please provide the original filter number, equipment brand and model, engine model where available, and any relevant dimensions. Our sales team can help review the information and confirm the next steps for a quotation.
