How is filtration precision (e.g., micron rating) defined?
Filtration precision is usually expressed in microns (μm), representing the minimum particle diameter that a filter can effectively capture. For example, a 10-micron filter means it can remove most particles with a diameter greater than or equal to 10 microns. The definition of precision may vary slightly depending on the test method (such as bubble point test, multi-pass test).
What is the pressure differential (pressure drop) of a filter? Why is it important?
Pressure differential refers to the pressure loss between the inlet and outlet when fluid passes through the filter. A new filter has a very small pressure differential. As contaminants accumulate, the pressure differential will gradually increase. Excessively high pressure differential can lead to reduced flow rate, increased energy consumption, and even damage to the filter element or filter housing. Therefore, it is an important basis for determining when to replace the filter element.
What housing material options are available for filters?
LOONG Filtration's industrial-grade filter housings are made of T304 stainless steel (standard) or T-316 stainless steel. They can maintain stable operation for a long time without leakage risks even under long-term, high-temperature, and strong-corrosion working conditions.
