A practical guide to choosing between dual-inlet and single-inlet centrifugal blowers, comparing airflow, static pressure, cost, noise and maintenance for HVAC and industrial ventilation systems.
Read More CAV vs VAV Fan Systems: Which Airflow Strategy Should You Specify?
Constant air volume (CAV) wins on stability, compliance and low maintenance; variable air volume (VAV) wins on demand-matched airflow and part-load energy. A field-level comparison of both strategies — including the series-stacking trap that unbalances CAV and VAV terminals, and how EC fans with central static-pressure control let both coexist.
