According to different application scenarios and requirements, we can supply magnetic filter bars with various diameters, gauss values and connectors, supporting a full range of customized solutions.

Magnetic filter bar is a simple, practical and widely used magnetic filter. It adsorbs surrounding ferromagnetic particles to remove iron impurities and protect downstream equipment. You may follow the steps below to select the proper magnetic bars:
Calculate Magnetic Field Strength
The accurate calculation of magnetic field strength is highly complicated. The following data is summarized based on our experience for your reference.
| Dry powder | 7000-8000gauss |
| Slurry | 9000-10000gauss |
| Nanoparticles | 大于12000gauss |
2. Determine the Dimensions of Magnetic Filter Bars
·Diameter: Magnetic bars are made of standard stainless steel tubes. The outer diameters and corresponding maximum gauss values are listed in the table below:
| Dia. | 6000Gs | 7000Gs | 8000Gs | 10000Gs | 11000Gs | 12000Gs |
| Ø16 | √ | |||||
| Ø19 | √ | √ | ||||
| Ø22 | √ | √ | √ | |||
| Ø25 | √ | √ | √ | √ | √ | √ |
| Ø28 | √ | √ | √ | √ | √ | √ |
| Ø32 | √ | √ | √ | √ | √ | √ |
| Ø38 | √ | √ | √ | √ | √ | √ |
·Length: Customizable length, maximum up to 1 meter.
3、Operating Temperature: Normally ≤80℃.
If higher temperature resistance is required, we can customize ferrite magnetic bars or samarium-cobalt magnetic bars, which can withstand temperatures up to 400℃.
4、Installation: The following installation types are optional according to different mounting requirements:

5. Magnetic Grates Display
Customizable on the number of magnetic bars, overall dimensions, gauss value and other parameters as required.
