General
Amiad’s exclusive Semi-Automatic assemblies provide a quick and efficient way for cleaning manual filters. Amiad’s Scanaway and Brushaway are add-on assemblies built for upgrading 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 turning the water off and extracting the filter screen for rinsing. With the semi-automatic assembly, the process flow is not interrupted during operation. Amiad’s semi-automatic assemblies are fitted with a Clogging Indicator to visually monitor the status of the filter element without disrupting the water flow.

How the "Clogging Indicator" Works
The Clogging Indicator is a special feature mounted on
the filter pressure check points and acts like a “traffic light”. When the pressure differential across the screen reaches a pre-set value of 0.5 bar (7 psi). The red button of the Clogging Indicator pops up to visually indicate that the filter needs to be cleaned. rotation of the brushes to wipe the particles from the inner screen surface. Opening the exhaust valve allows the dislodged particles to then be expelled through the exhaust valve. Brushing is done during the filtering process without interrupting


How the "Scanaway" Assembly Works
The Scanaway assembly consists of a suction-scanner and a hollow pipe with suction nozzles that face the inner side of the screen. Outside the filter, a handle is connected to the suction-scanner, allowing 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 causes 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 interrupting 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 insert d into the filter screen.
Outside the filter, a handle is connected to the brush unit, allowing the flow of process water through the filter.
