Fan Curves: mixed_flow_fan_18in_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 (%) |
|---|---|---|---|---|---|---|
| mixed_flow_fan_18in_1750rpm | 1,000 | 1.5 | Low flow; efficiency rising; mixed flow characteristic - no pronounced stall | 85 | 1.72 | 45 |
| mixed_flow_fan_18in_1750rpm | 2,000 | 2.1 | Mid-range; efficiency rising to BEP | 86 | 1.6 | 57 |
