Airflow performance curve
CF-11 No2A · 1.1 kW
Calculated curve · Total pressure · 2800 rpm
Calculated value – approximate
Calculated points (approximate)
| Q (m³/h) | Total pressure (Pa) |
|---|---|
| ≈ 1 200 | |
| ≈ 1 167 | |
| ≈ 1 116 | |
| ≈ 1 046 | |
| ≈ 959 |
The calculated shape uses catalogue ranges. Minimum flow is provisionally paired with maximum pressure and vice versa. These pairs and intermediate values are not confirmed by a factory curve.
