SPL Filter Disc | Stainless Steel Oil Filter Screen for Lubrication & Hydraulic Systems
SPL Filter Disc is a multilayer metal wire mesh filter designed for lubrication oil, hydraulic oil, fuel oil and other industrial fluid filtration applications.
Manufactured from stainless steel wire mesh, brass, copper or other metal filter media, SPL filter discs provide reliable particle filtration, high mechanical strength and good resistance to corrosion and wear.
Available in standard SPL-15, SPL-25, SPL-32, SPL-40, SPL-50, SPL-65, SPL-80, SPL-100, SPL-125, SPL-150 and SPL-200 configurations, as well as fully customized sizes and mesh combinations.
Custom SPL filter discs are available according to your drawing, sample, filter model or equipment requirements.
SPL Oil Filter Disc Manufacturer
Our SPL oil filter discs are manufactured using precision woven wire mesh and supporting metal layers to provide a stable filtration structure.
A typical SPL filter disc consists of multiple layers of fine and coarse woven wire mesh combined with a perforated support layer. The fine outer mesh performs the primary filtration, while the coarse mesh and perforated plate provide mechanical support and help maintain the filter's shape under operating conditions.
This multilayer construction provides a balance between filtration efficiency, flow capacity, mechanical strength and service life.
SPL filter discs are commonly used in oil lubrication systems, hydraulic equipment, marine machinery, diesel engines and industrial filtration systems.

We can manufacture custom SPL filter discs based on:
Inside diameter/Outside diameter/Mesh count/Wire diameter/Filtration rating/Number of layers/Frame material/Support plate/Filter housing/Customer drawing or sample
Multilayer SPL Filter Disc Construction
A typical high-performance SPL filter disc uses a multilayer woven wire mesh structure.
(1) Outer Fine Filter Mesh
The fine outer mesh provides the primary particle filtration function.
(2) Inner Coarse Mesh
The coarse mesh provides additional mechanical support and helps maintain the filtration structure.
(3) Perforated Support Plate
The perforated metal layer improves structural rigidity and supports the wire mesh under pressure.
(4 )Metal Edge or Frame
Depending on the application, the filter disc can be supplied with an aluminum, stainless steel, brass or other specified edge/frame.
Multilayer SPL filter construction is widely described in existing industrial SPL filter specifications, including four layers of woven wire mesh combined with a perforated support sheet.
SPL Filter Disc Mesh Options
Different woven mesh structures， such as plain weaving, twill weaving, dutch weving type. can be selected according to the required filtration performance.
Available mesh counts include commonly used specifications such as:
20 mesh | 40 mesh | 60 mesh | 80 mesh | 118 mesh | 158 mesh | 200 mesh | 264 mesh | 300 mesh | 363 mesh
Custom mesh combinations are available according to filtration requirements.
SPL Filter Disc Applications
SPL filter discs are designed for industrial filtration systems where metal filter media are required.
(1)Lubrication Oil Filtration: Used for removing solid contaminants from lubrication oil and maintaining oil cleanliness in industrial equipment.

SPL Filter Disc vs. Standard Wire Mesh Disc
| Feature | SPL Filter Disc | Standard Wire Mesh Disc |
|---|---|---|
| Multilayer construction | Available | Usually single layer |
| Support plate | Available | Optional |
| Oil filtration | Designed for | General purpose |
| Hydraulic filtration | Suitable configurations available | Depends on design |
| OEM SPL models | Available | Not necessarily |
| Filtration rating | Controlled by mesh combination | Mainly determined by single mesh |
| Mechanical strength | High with support structure | Depends on mesh |
| Custom edge/frame | Available | Optional |
| Reusable | Yes, application dependent | Yes, application dependent |
The main advantage of the SPL design is that filtration and mechanical support can be engineered together rather than relying only on a single wire mesh layer.
Quality Control
Each SPL filter disc should be checked according to the agreed technical specification.
