- Typical air flow
- For this class of centrifugal fan, air flow rates commonly range from 5,000 to 20,000 m³/h, depending on the specific impeller design and motor speed.
- Power supply
- Units of this type typically operate on a three-phase electrical supply, commonly 400V, 50Hz in the UK, with power ratings for the motor varying.
- Motor power
- Centrifugal fans in this range often feature motor powers from 2.2 kW up to 15 kW, providing sufficient power for demanding air movement tasks.
- Impeller type
- Ziehl-Abegg ER series fans commonly utilise backward-curved impellers, known for their high efficiency and quiet operation.
- Housing material
- The housing is typically constructed from galvanised steel for durability, with options for stainless steel in specific food-grade applications.
- Operating temperature range
- These fans are generally designed to operate effectively in ambient temperatures ranging from -20°C to +40°C, with some models capable of higher temperatures.
