Low pressure loss, typically ≤ 0.018 MPa.
No consumables – no need to replace filter bags or cartridges; the filter screen can be used for life, saving operational costs.
High adaptability – suitable for a wide range of water qualities and operational conditions.
Uninterrupted automatic backwashing – filtration continues during cleaning, making it ideal for continuous processes.

When selecting a self-cleaning filter, the filtration precision is a key consideration. These filters typically cover a filtration range of 50–5000 microns. For filtration requirements below this range, it is recommended to consider alternative filtration technologies.
