Product Details
The magnetic rod is the working element inside almost every PML grill and filter — and it's also sold on its own, for anyone building or retrofitting a magnetic separation system. Each rod is a hard ferrite ceramic or high-intensity rare-earth magnet, fitted inside a seamless drawn, heat-treated SS 304L tube, sized and finished to extract maximum holding strength from the magnet inside.
Choosing the Right Intensity
| Grade | Field Strength | Best For | Model Series |
| Low-Intensity | 2,500 ± 500 Gauss | Nuts, bolts, screws, broken washers — larger pieces from a distance | LMR 10–LMR 60 |
| Medium-Intensity | 6,000 ± 500 Gauss | Granule-size contamination, 1–4mm | MMR 10–MMR 60 |
| High-Intensity | 11,000 ± 500 Gauss | Fine ferrous particles down to 1 micron | HMR 10–HMR 60 |
All three grades run 100mm to 600mm in length, 25mm diameter, in SS 304 or SS 316 — the same rods that build up our grills and filters can be ordered individually for a custom rig or as replacements for an existing installation.
Key Advantages
- Precision-Built Tubes
Seamless drawn, heat-treated SS 304L tube, wall thickness optimised for maximum field strength at the surface.
- Three Intensity Grades
2,500 to 11,000 Gauss, matched to your contamination size.
- Standard Lengths
100mm to 600mm in 50mm steps — drop-in replacements for existing grills, or building blocks for a custom rig.
- Food and Pharma Ready
SS 304/316 construction throughout, suitable for hygienic processing environments.
Where It's Used
Plastics, food processing (wheat, sugar, coffee, tea, grains, pulses, flour, spices, milk), pharmaceutical, chemical, ceramic, colours and paints, pigments, ink and refractory industries.
Frequently Asked Questions
Can I order rods to fit my existing grill?
Yes — tell us the length and diameter of your current rods and we'll match or upgrade the intensity grade.
What's the difference between the three grades?
It's the size of contamination each one is designed to catch — low-intensity for larger tramp metal, medium for granule-size particles, high-intensity for fine fines down to 1 micron.
SS 304 or SS 316 — which should I choose?
SS 316 offers better corrosion resistance for aggressive or wet environments; SS 304 is standard for general dry-material use.
