6-blade impeller Vpro

low noise level

Overview
ZIEHL-ABEGG designs the Vpro impeller for versatile industrial and cleanroom applications. The unit combines compact installation options with a blade geometry optimised to reduce tonal noise while maintaining high volumetric flow and efficiency.

Product specification:
Free-running Vpro impeller with 6 backward-curved, fluted blades in frame sizes 190 to 630 mm. Impeller made of high-performance composite material. Version available with inlet nozzle. Volume flow up to around 18,000 m³/h (free blowing). Maximum static pressure increase up to 1,300 Pa. GR module for compact integration in customer applications/devices for horizontal and vertical air feed.

Properties & special features:
High volumetric flow rates and high efficiency. Low acoustic power levels due to special three-dimensional blade geometry and reduced rotational tone. Suited for low-pressure applications.

Motor concepts:

• External-rotor motors: ECblue EC technology with integrated controller matched to the fan
• AC technology

Typical applications
Packaging and production machines; cleanroom workstations; cleanroom ceilings / ventilation-filtration modules (FFU).
