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. ...
The Hydraulic Filter 4688140 is a replacement hydraulic filter element developed for heavy-duty Hitachi excavators and construction equipment. It is also referenced by Hitachi part number 4253230 and can be cross-checked with aftermarket numbers including Baldwin PT23560, Fleetguard HF29151, and HiFi SH60430. Public cross-reference information confirms these numbers as corresponding hydraulic filter applications.
Designed for demanding equipment maintenance environments, this filter helps remove contaminants from hydraulic oil before they can affect sensitive hydraulic components. It is suitable for professional maintenance programs, aftermarket replacement supply, and bulk purchasing by retailers, wholesalers, filter shops, and after-sales service providers.
Hydraulic systems in large excavators operate under demanding working conditions. Dust, metal particles, and other contaminants can enter hydraulic oil during operation or maintenance. A properly matched filter element helps control these contaminants and supports cleaner hydraulic fluid circulation.
This product is identified by 4688140 and is also associated with Hitachi 4253230. It can be used as a reference when sourcing an aftermarket replacement for selected Hitachi excavator hydraulic filtration applications. Always verify the original part number, filter dimensions, and equipment configuration before ordering.
For distributors and service companies, choosing a Cost Effective Hydraulic Filter Replacement can help control routine maintenance costs while maintaining a consistent supply of replacement elements. With a minimum order quantity of 60 pieces, this model is suitable for wholesale purchasing and inventory planning.

This Hydraulic Filter for Construction Equipment is specified for selected Hitachi EX-series excavators, including:
Public application references also identify 4253230 as a hydraulic strainer/filter application on EX1800 and EX1800-2 machines. Because equipment configurations can vary by model, serial number, and hydraulic system position, buyers should confirm the original part number and dimensions before placing an order.
When an original part number is unavailable, Hydraulic Filter By Size can be an effective starting point for product identification. The 4688140 replacement element has an outside diameter of approximately 84 mm, a height of 162.5 mm, an inside diameter of 38 mm, and a gasket outside diameter of 82 mm. These measurements can help purchasing teams compare replacement options and reduce the risk of ordering an incorrectly sized filter.
The filter is manufactured according to a defined dimensional specification for selected heavy-duty hydraulic applications, with a compact cylindrical design and controlled sealing dimensions.
Accurate dimensions and multiple cross-reference numbers make product identification easier for distributors and maintenance suppliers. The replacement format also supports aftermarket sourcing for machines where regular hydraulic filtration service is required.
For retailers, wholesalers, and after-sales service companies, a dependable replacement supply can simplify maintenance planning, reduce purchasing delays, and help maintain an appropriate inventory of commonly requested hydraulic filter elements.
Independent published cross-reference data connects 4688140 and 4253230 with PT23560, HF29151, and SH60430. Fleetguard application information also lists Hitachi 4253230 and 4688140 with the EX1800 and EX1900 series, providing useful verification for professional buyers. :contentReference[oaicite:2]{index=2}
