In applications with low pollution and smaller filter replacement intervals usually piston screen changers are used. These systems are primarily used in the post-industrial, post-production and new-product sectors.
Depending on required flow rates and different operating modes, customers choose between the discontinuous version – commonly with one piston – or the continuous one – with two pistons version.
At higher level of contamination and more frequent filter change intervals, a continuous backwash version is available.
