Meshes for filtration are usually manufactured with closely spaced wires. The mesh opening of the filter cloth – also known as the filter fineness or pore size – tends to be triangular and cannot be determined geometrically with simple measuring equipment. The filter fineness can be calculated from the geometry or obtained in tests – preferably under operating conditions. Filter cloths have finenesses of 5 – 500 μm, but depending on the filter cake that forms during the application, they can also achieve much smaller values.
Please feel free to contact us for the flow measurement of your filter cloths. With our modern testing equipment, we can determine the airflow.
We are looking forward to performing customs tests for your currently used meshes – including existing orders for DDD filter cloths, of course.
