Tube magnets also name magnetic tube,magnetic filter bar,magnetic filter rod that consist of 304 or 316 stainless tube and strong permanent magnets ,such as Neodymium magnets,SmCo magnets, Ferrite Magnets. They are basic magnetic elements for grate magnets,magnetic grid,drawer magnets, rotary grate magnets, hopper magnets,magnetic grate separators,liquid trap magnets for removing ferrous metal from bulk solids and powders materials,such as milk powder,chocolate, grain, flour, chemical powders or granules, plastic, pigment etc.the max magnetic force of magnetic tube can up to 13000Gs, which is very fit to catch very fine ferrous contamination from fine powder or liquid materials. welcome contact us for detailed information Call Us Today! 86-574-27667267 | Email:


Magnetic filter bars can be installed at every required location in systems used to transport solid or liquid product. The filter bars are comprised of an extremely power- ful Neodymium magnet system in a watertight stainless-steel housing.
Features :
1. Standard bars is 25mm(1 inch) in diameter and any length per customer’s request,the Max length up to 2500mm, square or other magnetic tubes with different shapes and dimensions are also available.
2. HANGSENG MAGNETECH magnetic bar usually made of seamless 304 stainless steel tubes or 316 stainless steel tubes can be fine polished and full welded to meet food grade or pharmacy application .
3. Usual max working temperature is 80℃, we can offer up to 350℃ to meet your special applications.
4. Various ends-nail head, thread hole, double screw bolt and other kind ends are also available.
5. By using ferrite magnets or different grade rare earth magnets,different magnetic strength are available to meet
every customer’s requirement, the highest magnetic strength of Diameter 25mm(1 inch) tubes can achieve 13,000GS(1.3T).
Applications :
Magnetic bars are the main part of different magnetic grate separators. They can effectively remove ferrous chips and
metal particles from loosely packed, free flowing materials.
