With the new nozzle technology available today the induction systems supply fan static pressure can be dramatically reduced (often by 1.0 - 3.0" w.c.) when retrofitting an entire system with new induction units. In addition the primary airflow can often times also be reduced (within the constraints of the ventilation air requirement).

The net result of these decreases in static pressures and primary airflows due to the use of the new induction units is lower fan energy consumption and operating costs.
