- Typical Airflow Capacity
- For this class of centrifugal fan, airflow can typically range from 5,000 to 20,000 m³/h, depending on static pressure requirements.
- Power Supply
- Units of this type commonly operate on a 400V, 3-phase, 50Hz supply, with motor power typically ranging from 5.5 kW to 15 kW.
- Impeller Type
- NPA series fans typically feature backward-curved impellers, known for high efficiency and non-overloading characteristics.
- Construction Material
- Casings and impellers are commonly constructed from robust mild steel, with options for stainless steel in specific food-grade applications.
- Noise Level
- Noise levels for centrifugal fans of this size typically range from 80 to 95 dB(A) at full load, requiring consideration for workplace acoustics.
- Mounting Orientation
- These fans are commonly designed for various discharge orientations, allowing flexibility in ductwork connection.
