A micron rating indicates the ability of a liquid filter to remove contaminants of the particle sizes. Micron rating together with the associated beta ratio and efficiency are very important factors to describe the performance of a filter.
A filter rating of "15 micron" has some ability to capture particles as small as 15 microns. To make a micron rating be truly useful, it is essential to know the filters' removal efficiency of the specific particle size.The two most common terms used to describe the micron ratings are nominal and absolute.
Nominal Micron Rating expresses the ability of the filter to capture particles of a specified size at an efficiency between 50% and 90%. But it may range anywhere from 50 – 98.6% efficient at removing a specific particle size.
Absolute Micron Rating means that the filter is capable of removing at least 98.7% of a specific size particle. This rating is more informative than the nominal micron rating.
Usually MAISHI WIRE MESH MANUFACTURE GROUP will offer both the nominal and the absolute micron ratings. Typically the nominal rating is a 50% efficiency rating. However, this should be verified if not given to you.
If you got the micron rating from another manufacturer, it is important to ask if it is the nominal or absolute rating, as well as the percent of efficiency rating and contaminant capacity. This will allow you to better assess the performance of the filters being compared.
MAISHI produce and supply high quality mesh products and offer innovative services for those industries and processes that require a high level of specialization in application: printing, filtration, clothing lining and composites. Our market gradually turned to international trade from domestic sales since 2000. MAISHI products have been exported to more than 90 countries and regions around the world. And we have more than 500 global partners.
