| Automatic Filtration System Process
 Inlet opens allowing a flow of water from the inlet manifold into the filter, through the 5 elements of filtration, to the outlet manifold and out to the field.
Backflush Process
Inlet is closed. Drain port opens allowing clean water to flow from the outlet manifold in the opposite direction into the filter. The discs are cleaned, particles are flushed out from the filter through the drain manifold.
When the filters are loaded (with particles) the difference of pressure between the inlet and the outlet of the Galaxy rises. A differential pressure gauge detects the critical difference of pressure pre-programmed transmitting a signal to the control unit which begins the backflush process of the filters in the battery one after the other.
Only one filter at a time is cleaned, while the remaining filters in the Galaxy Automatic Filtration System continue to supply clean water to the downstream for the backflush process.
Automatic Filtration System Product Advantages
• compact, simple design.
• Automatic, self-cleaning, self-flushing system triggered by pressure differential and/or pre-set time.
• Equipped with new spine for maximum performance and low maintenance.
• Simple installation and operation.
• Short backflush cycle - saves backflush water.
• Flushing cycle has a regulated volume, short and environmentally friendly, minimizing the use of flushed water.
• Innovative design captures and stores large amounts of solids - reducing the need for backflushing.
• No interruption of flow during backflush cycle.
 Automatic Filtration System Applications
• For surface and well water
• For systems requiring high volumes of water
