DEL AOP PRESSURE DROP CHARACTERIZATION
NOTE: Tested on simulated recirculation system using a Pentair lntellio variable speed pump. No back pressure added. Back
pressure will raise the inlet pressure (lter pressure) but reduce the pressure drop slightly. Actual results will vary depending
on pump and plumbing variables.
