Long Description
The Prodigy Pressure Relief Collar (PRC) slips over the diffuser inlet to provide a simple and inexpensive solution to control inlet static pressure. A PRC requires a plenum return and is recommended for installations with a constant volume fan. As duct pressure increases past 0.25 in. w.g. calibrated shutters gradually open to release excess air into the ceiling plenum. (Note: The PRC is not available for the PLD Prodigy linear diffuser.)
Note: Image shows item expanded, item will be shipped with shutters closed.
