Notes:

1. At rated voltage, after 3 minutes.

2. At rated voltage, room temperature, 65% humidity, 0 inch H

20 static pressure.

3. At rated voltage, 0 CFM airflow.

4. Measured in an anechoic chamber as per ISO3745/GB4214-84 at rated voltage, with background noise 20±2 dBA at 1 m from the fan intake.

5. Typical rated sped is measured as RPM±600 at rated voltage

6. All specifications are measured at 25°C, 65% relative humidity unless otherwise specified.
