FAQ
Magnetic Filters & Separators — FAQ
What is the temperature limit of magnetic filters?
Standard NdFeB filters work up to 80 °C; SmCo-based filters extend to 300 °C for hot processes.
Are the tubes food-grade?
Yes, we use SS304 or SS316 stainless steel tubes with sealed welds for food and pharmaceutical lines, meeting hygiene requirements.
Do you provide free samples for testing?
Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.
Can the factory produce to my drawing with special tolerances?
Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.
