The AMF2 filters remove dirt particles as water flows through multi-layered microfiber cassettes (1). These are attached to collector pipes which allow the processed water to flow from the filter via the outlets (2). Dirt particles that accumulate on and in-between the microfiber layers create a pressure differential. At a preset pressure differential value or time interval, the control unit activates the self-cleaning cycle, described as follows:

The inlet (3) and outlet (4) valves close and the drain (5) valve opens. After the filter vessel empties, the booster pump (6) delivers pressurized water to the shuttle pipe (7) on which the flush nozzles are mounted (8). These nozzles straddle the cassettes and spray both sides of a cassette with high powered jet streams (9) that penetrate the microfiber layers and dislodge the debris (10). When these jet streams hit the plastic cassette support, they reflect outward, carrying the debris off the cassettes and out the drain.

This process ensures 100% effective cleaning. The piston assembly shuttles the spray nozzles across a single row of cassettes on each stroke. When the nozzles reach the end of a row, the turn mechanism forces the filter package to index to the next row of
cassettes. The piston then strokes in the opposite direction, cleaning the cassettes as the nozzles traverse them.

After cleaning all 35 rows of cassettes, the filter is clean. The drain valve closes and the inlet valve re-opens, filling the filter vessel. After the vessel is full, a “filter to waste” valve opens. This eliminates any residual contaminant that may have entered the collector pipes during the flush process. After this, the outlet valve opens and the filter is once again on-line.
