    Additional Information

    The Thompson Filter's internal flow patterns are responsible for making our unique product so effective. As water flows up through the filter housing and deflects off the surface of the conical shaped filter screen, sediment is effectively forced back down, away from the screen, into the large debris reservoir. The sediment is then easily removed through the flush port. Effective separation of the water and the sediment is achieved while minimizing debris contact with the screen.

    The Filter/Strainer vessel is purged while online and in operation. By opening a valve on the flush port, all debris in the lower reservoir is purged from the vessel, as shown. Backflushing or taking the unit off-line is not required to perform this flushing procedure.
