The Industrial Centralized Lubrication System Oil Filter is a filtration component designed to remove solid contaminants from lubricating oil before it enters pumps, distributors, metering components, and lubrication points in centralized lubrication systems.

It is suitable for industrial machinery requiring clean and stable oil delivery through centralized or automatic lubrication circuits.

Product Features

Fine Particle Retention
Protects tight-tolerance dosing valves and progressive dividers by trapping micro-particulates, preventing mechanical jamming and erratic lubricant distribution.

Pressure-Resistant Construction
Built to withstand continuous working pressures up to 45 bar, maintaining full structural integrity during oil delivery pressure surges.

Compact In-Line Integration
Directly installs into main or secondary lubrication supply lines, eliminating the need for bulky mounting brackets or auxiliary piping adapters.

Low-Flow Circuit Optimization
Specifically calibrated for low-flow automated delivery systems (up to 3 L/min), ensuring thorough filtration without causing excessive line pressure drop.

Washable Metal Media
Multi-layer sintered stainless steel element offers superior mechanical rigidity and can be ultrasonically cleaned, significantly lowering lifetime MRO replacement costs.

Centralized Lubrication System Compatibility

Progressive Lubrication Systems: Installed upstream of progressive metering blocks to ensure debris-free cycling of divider valves.

Single-Line Resistance Systems: Fits into main delivery lines to protect injectors and metering orifices from sludge accumulation.

Automated Machine Lubrication: Shield central pump units and solenoid valves from recycled oil contamination.

Direct Point-to-Point Lines: Connects directly prior to critical friction points on spindles, guideways, and drive chains.

Quality Control & Testing

Material & Thread Verification: Spectrometric analysis for metal purity; 100% plug/ring gauge inspection on G1/8 ports.

Pressure & Leak Testing: Every unit undergoes hydrostatic testing to guarantee integrity at 45 bar working pressure.

Element & Traceability Inspection: Bubble-point testing verifies 3 μm pore uniformity; batch IDs are laser-engraved for full tracking.

FAQ

Q: How do I choose the right centralized lubrication oil filter?

A: Select the filter based on the existing system configuration, filtration requirement, oil flow, operating pressure, connection, and available installation space.

Q: Can I use this oil filter as a replacement for another brand?

A: Yes. Replacement compatibility can be evaluated using the existing filter model, dimensions, connection, filtration specification, or a physical sample.

Q: Can you manufacture a filter based on a sample?

A: Yes. Sample-based production is available for OEM replacement applications. The sample can be evaluated for dimensions, connections, filter construction, and required performance.

Q: What is the minimum order quantity for OEM oil filters?

A: MOQ depends on the filter specification, customization requirements, and production arrangement. Standard and OEM orders can be quoted separately.

Q: Can I order samples before placing a bulk order?

A: Yes. Samples can be arranged for specification verification and installation testing before bulk production.

Q: What information should I provide when requesting a quotation?

A: Provide the required quantity, existing part number or drawing, application, filter specifications, connection details, and any OEM requirements available.

Q: How long does it take to produce a customized oil filter?

A: Lead time depends on the product specification, customization level, and order quantity. The confirmed production schedule is provided with the quotation or order confirmation.

Q: How are centralized lubrication oil filters packaged for export?

A: Filters are individually protected and packed in export cartons. OEM labels, shipping marks, and customized packaging can be arranged for bulk orders.

Q: Can you supply replacement filters for long-term maintenance programs?

A: Yes. We can support repeat orders and replacement supply based on an approved specification, sample, drawing, or OEM part number.
