Plastic filter type Semi-Automatic

Turn-of-a-handle for cleaning mechanism

The semi-automatic filter installation kits offer a quick and efficient solution for cleaning manual filters.

Scanaway and Brushaway are installation kits for upgrading the plastic filters to semi-automatic operation by triggering a cleaning mechanism to clean the filter surface using a simple hand crank.

Upgrading to a semi-automatic filter eliminates the need to interrupt the water supply and remove the fine strainer for cleaning. In semi-automatic operation, the flow is not interrupted.

The semi-automatic filters are equipped with a blockage indicator so that the status of the fine screen can be read visually without interrupting the flow.

How the “Scanaway” Assembly works

The Scanaway assembly consists of a suction-scanner, a hollow pipe with suction nozzles, that is facing the inner side of the screen. Outside the filter a handle is connected to the suction-scanner, allowing the turning of the scanner in a spiral movement so it rotates inside the screen surface without touching the screen mesh. Opening the exhaust valve at the filter lid creates low pressure conditions in the suction scanner, which cause the scanner nozzles to suck in the dirt particles from the screen surface and expel the dislodged particles out through the exhaust valve. Scanning is done during the filtration process without having to stop the flow of process water through the filter.

How the “Brushaway” Assembly works

The Brushaway assembly consists of nylon brushes fitted on a frame and inserted into the filter screen. A simple handle, outside the filter, allows brushing away particles from the inner screen surface and expel them out from the filter through the exhaust valve. Brushing is done during the filtering process without having to stop the flow of process water through the filter.
