A reverse flow rinsing fluid filtering device, particularly for large diameter piping. Housing (12) has inlet port (14), outlet port (20) and a battery of filtering discs divided into three groups D1, D2 and D3 by partition rings 80a and 80b. In the rinsing stage, when the filtering discs become separated from each other, the discs of each group are supported on one of the partition rings thereby reducing the effect of the self-weight of the discs
