Fan Curves: backward_inclined_24in_1750rpm
Representative fan performance curves for common HVAC fan types — static pressure (in. wg), BHP, total efficiency (%), and sound power level (dB) at multiple airflow (CFM) operating points
| fan family | flow cfm | bhp (hp) | notes | sound power dB (dB) | static pressure inwg (inWG) | total efficiency pct (%) |
|---|---|---|---|---|---|---|
| backward_inclined_24in_1750rpm | 2,000 | 3.8 | Rising curve approaching peak pressure | 88 | 3.6 | 48 |
| backward_inclined_24in_1750rpm | 4,000 | 5.9 | Mid-range; efficiency rising toward BEP | 89 | 3.35 | 58 |
