Multi-blade impeller Cpro

radial-flowlow noise levelcorrosion-resistant

Overview
The Cpro ZAmid® centrifugal impeller combines very low weight with high stability and efficiency. The ZAmid® high-performance composite reduces mass compared with steel, extends component lifetime, lowers power consumption and significantly reduces sound emission. The impeller's three-dimensional blade geometry is designed for demanding temperature, hygiene and air-conditioning applications.

Product specification
Free-running centrifugal impeller Cpro made of ZAmid® with 7 backward-curved, fluted blades, available in diameters 250–630 mm. Free-blowing volume flows up to 30,000 m³/h and static pressure increase up to 2,500 Pa. Versions with hub and inlet nozzle including a volume flow measurement device. GR modules for compact installation in customer systems with horizontal or vertical air feed. ER built-in fans for vibration-damped use in central air-conditioning units with horizontal air feed.

Properties & special features
Impeller with rotating, non-fluted diffusor for very high efficiency and favorable acoustic characteristics. Special 3D blade geometry reduces tonal noise. ZAmid® high-performance plastic enables an operating temperature range of -35 °C to +80 °C and offers high chemical resistance. Fire-protection-certified ZAmid® available to meet DIN EN 45545-2.

Motor concepts

• External-rotor motors: ECblue technology with integrated controller matched to the fan
• External-rotor motors: AC technology
• Internal-rotor motors: PMblue EC (permanent-magnet) with built-in controller
• Internal-rotor motors: AC technology
