This D25 x 200mm Magnetic Rod has a threaded M8 Hole, with an outside diameter of 25mm and a length of 200mm. By using N50 grade it has a high Gauss reaching 11,000-12,000. They are widely used in the food and dairy industry to protect their product from ferrous metal contaminant. From large magnetic separator systems to small single drawers these rods are able to extract any ferrous contaminant.
2. Length can be up to 1,000 mm and even longer per customers' requirements.
3. Standard fixation with female threads of M6, M8, M12 or male threads of M6, M8, M12, or inch threads according to customers' requirements.
4. Customized designs are welcome
5. Laser welding and normal welding (argon protecting welding) optional.
6. Easy to assemble/remove the tubes with the standard threads on the tube' ends on/from the frame.
7. Maximum flux density can reach 12,500GS on the rod surface
8. Application: Food industry / Dairy industry / Chemical industry / Water treatment / Heating solution / Plastic industry / Textile industry / Pharmaceutical industry
