Important Note:
When choosing a pressure drop to size the WARDFLEX® system the minimum operating pressure of the unit must be
considered. Choosing a pressure drop that will reduce the supply pressure below the minimum operating pressure of the unit will
cause the unit to perform poorly or not at all.
Example:
System Supply Pressure: 7 inches W.C.
Unit minimum operating pressure: 5” W.C.
The use of a 3 inch W.C. pressure drop would result in a minimum inlet pressure at the unit of 4 inches W.C. In this case an
alternate pressure drop of 2 inches or less should be selected to meet the minimum operating pressure of the unit.
