During normal operation of the Flow Guard filter, unfiltered liquid flows into the lower portion of the vessel and passes through the filter elements into the upper part of the tank. There, a portion of the clean liquid remains in the tank's built-in reservoir for backwashing. The balance of the clean liquid flows through the clean liquid outlet.
The regeneration cycle begins by isolating the vessel from the dirty liquid inlet and the clean liquid outlet. The reservoir's backwash outlet line is opened and pressurized air forces the clean liquid back into the lower portion of the tank. This high-pressure, high-volume flow effectively cleans the filter elements. The backwash liquid is then removed from the vessel through the backwash liquid outlet. The entire clean-up process requires no more than 5 seconds to complete.
At the conclusion of the regeneration, or backwash cycle, the dirty liquid inlet is reopened and liquid flows back into the vessel to purge any air before the outlet line is reopened for normal operation.
