Filter selection

Substances to be filtered, physicochemical properties of the substances, corrosivity, flow rate, operating pressure, etc

Filter: select the mesh size based on the particle size to be filtered. There are also factors such as pressure and the substances being transported.

In regular work, Y-type connectors are more commonly used for smaller diameters such as DN200 and below, while T-type connectors are used for larger diameters. What could be the reason? When selecting filters, aside from installation conditions, what are the differences between Y, T, and basket types? Thank you~~

Also looking for an answer – the people above still haven’t clarified the question asked by the original poster! ~

The filtering criteria need to be specified so that everyone can help
