Manual self-cleaning filters are intended to be used in waste water, even if it contains sand, and in all those cases where a non-stop filtering action is required.
Their special feature is that they can be cleaned without being removed.
Once the filter has reached its max. clogging level, just open the drain valve and turn the handle onto the filter to clean it and restore its original filtering rate.
An inner scanning system sends dirt particles into the tube, thus ensuring longer cleaning intervals.

手动自清洗过滤器被制造用于废水处理，即使废水中含有沙子并且在需要不间断过滤动作的情况下。
它们特殊的特点是不拆卸就可以被清洗。
一旦过滤器达到最大堵塞水平，就打开排水阀并将过滤器上的手柄转动以便清洗过滤器及恢复原来的过滤能力。
由于有内部扫描系统，灰尘颗粒进入管道，从而确保更长的清洗间隔。
