9100-IF: VAV Diffuser

Submittal Sheet


The 9100-IF is part of Young Regulator’s “Simple Zone” Product line.  The goal is to make Stand-Alone airflow zoning easier than ever.

The 9100 is a plaque-style diffuser.  It has been designed to maintain the coanda effect, discharging air along the ceiling for predictable, even comfort.


We have added an interface board to make wiring simple and handle the modulation and auto-changeover.
