Amiad Water Systems Semi-Automatic Filters

Amiad's exclusive semi-automatic assemblies provide a quick and efficient method for the cleaning of manual filters. Amiad's Scanaway and Brushaway are add-on assemblies designed to upgrade Amiad's steel and plastic filters to semi-automatic operation by adding a simple turn-of-a-handle cleaning mechanism to the filter's screen. Upgrading a manual filter to semi-automatic operation eliminates the need for flow disruption to extract the filter screen for rinsing. With the semi-automatic assembly, the process flow can continue without interruption.

Amiad Scanaway Assembly

The Scanaway assembly consists of a suction-scanner, a hollow pipe with suction nozzles that faces 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, rotating it within 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 causes the scanner nozzles to suction 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 disruption to the flow of process water through the filter.

Amiad Brushaway Assembly

The Brushaway assembly consists of nylon brushes fitted on a frame and inserted into the filter screen. 

A simple handle, located outside the filter, allows the brushing away of particles from the inner screen surface and expulsion out from the filter through the exhaust valve. Brushing is done during the filtering process without disruption to the flow of process water through the filter.
