Magnetic Filter Bar
A magnetic filter bar is a tool commonly used to clean impurities from liquids and gases. This tool typically consists of one or more magnetic rods that capture and filter impurities in liquid or gas lines to protect equipment from damage.
Magnetic filter rods can filter liquids, gases, powders and solid materials very well. Whether it treats water, oil, fuel or starch, glass, minerals, etc., it can get good results.
Magnetic filter rods have good filtration efficiency. Due to its magnetic adsorption property, it can filter out tiny impurities effectively, thus improving the quality and purity of products.
Magnetic filter rods are easy to clean, maintain and replace. Due to its simple structure, it can be easily disassembled and cleaned to maintain good usage. If it needs to be replaced, simply replace the magnetic filter bar.
Magnetic filter rods are economical and practical. Compared to conventional filters, magnetic filter rods require no additional energy or cost and can perform filtration tasks quickly and efficiently, thus reducing production costs and increasing productivity.

Temperature: The material and housing of a magnetic filter bar should be able to withstand the high or low temperatures of its application environment.
| Grade | Max. working Temp | Curie Temp | Supportable magnetic grade |
| N | 80℃/176℉ | 310℃/590℉ | N30-N55 |
| M | 100℃/212℉ | 340℃/644℉ | N30M-N52M |
| H | 120℃/248℉ | 340℃/644℉ | N30H-N52H |
| SH | 150℃/302℉ | 340℃/644℉ | N30SH-N52SH |
| UH | 180℃/356℉ | 350℃/662℉ | N28UH-N45UH |
| Eh | 200℃/392℉ | 350℃/662℉ | N28EH-N42EH |
| AH | 240℃/464℉ | 350℃/662℉ | N30AH-N38AH |
Curie Temp: also called Curie point or magnetic transition point, is the theoretical working temperature limit of magnetic materials, beyond the Curie temperature, the magnetic properties of magnetic materials will disappear completely.
Max.working Temp: If the maximum working temperature is exceeded, the magnetism of magnetic material will be demagnetized and irreversible loss will occur.
Relationship: the higher the Curie temperature, the higher the working temperature of the material, and the better the temperature stability.
Magnetic force: The magnetic force of a magnetic filter bar depends on the type and number of magnets inside it. A stronger magnetic force improves the filtration efficiency but may also affect the flow rate of the liquid or gas.
Material: The material of the magnetic filter rod should be compatible with the liquid or gas being filtered and should not be subject to corrosion.
Because of its excellent corrosion resistance, stainless steel is a commonly used material in many applications. However, for applications that require a higher level of corrosion resistance, it is equally important to choose a higher grade of stainless steel material. Examples include 316 or 316L, which are particularly suitable for industries such as food or chemical processing, where exposure to harsh chemicals or high humidity may occur.
