Product specification:

Single-ended extracting, backward-curved motor impeller. Available in frame sizes 355 to 560 mm. This allows for volume flow rates of up to 16,000 m³/h, max. static pressure increase up to 900 Pa.

Properties & special features:

Energy-optimised for operation in tube and duct fans, in which air is supplied axially and is then forced out again. The diagonal outflow means there are fewer deflection losses than for centrifugal fans. Due to the static pressure increase that can be achieved, they can be used anywhere where an axial fan would not be able to generate sufficient pressure increase.

Motor concepts:

External rotor motors:

• ECblue EC technology with integrated controller matched to the fan
• AC technology
