Airflow performance curve
4-79A No3 · 1.5kW · 2900rpm
Calculated curve · Total pressure · 2900 rpm
Calculated value – approximate
Calculated points (approximate)
| Q (m³/h) | Total pressure (Pa) |
|---|---|
| ≈ 1 196 | |
| ≈ 1 131 | |
| ≈ 1 032 | |
| ≈ 896 | |
| ≈ 726 |
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.
