Page 13: Blower Sizing
INSTALLATION CA-Series Indoor 2.2 BLOWER SIZING Most “low airflow” problems in the field are caused by under-sized blowers. Systems can under-perform if the designer does not make sufficient allowance for duct leakage, variations in duct layout from ideal design, less-than-ideal blower outlet conditions, dirty filters, and the like. In general, ventilation systems with energy-recovery components tend to need blowers with relatively high static pressure curves. -
