The present invention relates to a filter module, and more particularly, to a tangential flow filter module and a tangential flow filter assembly using the tangential flow filter module.

In recent years, the production and application of microspheres have become increasingly widespread, and the basic requirement for the application of microspheres is the uniformity of particle size, so a screen is usually used to sieve the microspheres to obtain microspheres of similar size.

However, the common screen meshes are usually made by weaving, so the size of the screen holes is difficult to grasp and the precision is poor. In addition, when the screen is used for a long time, the screen hole will often be blocked, which will seriously affect the screening effect.

Therefore, one objective of the present invention is to provide a tangential flow filter module and a tangential flow filter assembly using the tangential flow filter module, which can improve the filtration precision and efficiency of microspheres.

According to the above objective of the present invention, a tangential flow filter module is proposed. The tangential flow filter module includes a plurality of plate units connected in series.
