Product Details
High-flow, high-contamination fluid applications — grinding coolant, honing and milling fluids, hydraulic oils under heavy load — need more than a single-stage magnetic trap. The PML Self Cleaning Filter is a two-chamber, self-purging design built for exactly that: fluid enters the first chamber for primary filtration, then flows into a second, slower chamber where final filtration takes place before the cleaned fluid returns to your process.
What Clean Fluid Delivers
Running fully filtered fluid, free of micron-sized ferrous particles, directly improves surface finish and fluid flow on precision machining operations — while cutting scrap reduction costs and downtime caused by contaminated coolant or hydraulic fluid.
Standard Range
| Model No. | Height A (mm) | Diameter B (mm) | Flange CTC C (mm) | Elements | Flow Rate (L/min) |
| SCF1 | 835 | 200 | 540 | 6 | 500 |
Larger models (SCF2 and above) step up in height and diameter to handle higher flow rates — tell us your required throughput and we'll confirm the right model.
Key Advantages
- Two-Chamber Design
Primary and final filtration stages in one unit for consistently clean output, even on high-contamination fluids.
- Self-Purging
Reduces the operator intervention needed to keep the filter performing at rated capacity.
- Built for High Flow
Designed specifically for high-flow, high-contamination industrial applications like grinding and honing coolant loops.
- Improves Process Quality
Cleaner fluid means better surface finish, less scrap and fewer unplanned stops.
Where It's Used
Grinding, honing, milling and fine-finishing coolant systems, plus liquid pharmaceutical products, liquid chemicals, liquid food products, lubricants, coolants, hydraulic oils and slurries.
Frequently Asked Questions
How is this different from the standard Magnetic Filter?
The standard filter is a single-chamber design; this Self Cleaning Filter uses two chambers — primary and final filtration — specifically for high-flow, high-contamination applications like grinding and honing coolant.
What flow rates does it support?
Standard models start at 500 L/min and scale up — tell us your required throughput and we'll confirm the right model or a custom build.
Does it need manual intervention?
It's designed to reduce operator intervention versus a standard filter, though periodic maintenance checks are still recommended for high-contamination duty cycles.
