Product Drawing
The product drawing shows a DC axial fan with dimensions and mounting details. Key dimensions include:
- Overall size: 92 x 92 x 32 mm
- Mounting hole diameter: Ø 100.1 ± 0.3 mm
- Mounting hole spacing: 82.5 ± 0.2 mm and 89 ± 0.3 mm
- Fan thickness: 32 ± 0.15 mm
- Impeller diameter: Approximately 92 mm
- Mounting screw hole diameter: 4.5 ± 0.2 mm
- Corner to corner dimension: 310 ± 10 mm
- Depth from mounting surface to impeller: 22 ± 0.15 mm
- Depth from mounting surface to motor housing: 4.3 ± 0.15 mm
- Overall depth including mounting flange: 6 ± 1 mm
The drawing indicates the airflow direction is exhaust over struts and the direction of rotation is clockwise when viewed toward the rotor.
Performance Curves
The performance curves illustrate the relationship between airflow (m³/h and cfm) and static pressure (Pa and in H₂O) for the 3314 NN DC axial fan. The curves show:
- Curve 1: Represents the fan's operating point at various airflow rates.
- Curve 2: Shows the fan's power consumption in Watts at different airflow rates.
- Curve 3: Indicates the sound pressure level in dB(A) at different airflow rates.
- Curve 4: Displays the sound power level in B at different airflow rates.
The graph indicates that at maximum airflow (80 m³/h), the static pressure is approximately 0 Pa. As airflow decreases, static pressure increases. Power consumption is relatively constant across the operating range.
