Flow Control and Filter Mode

The Filter Mode feature provides the ability of overcoming head pressure loss to provide the required flow
through the plumbing. The flow that the unit can provide is limited by the installed plumbing. If more flow is
demanded than the IntelliFlo can provide, it will ramp to full speed and create pressure.

The following example shows a ramp as flow increases from 50 to 75 GPM.
