Air blower S

centrifugalHVACfor ventilation

Overview
Anywhere air needs to be moved, ZIEHL-ABEGG is in their element. The proven single- and double-inlet centrifugal fans from the S series with AC technology in a compact housing are suited for a wide range of applications such as clean rooms or controlled residential ventilation, providing reliable performance and efficiency. Thanks to their high number of blades, they achieve a high performance density with low noise emissions.

Product specification
Single-ended and double-ended centrifugal fans in a compact housing with forwards-curved blades. Available impeller diameters: single-sided 280–400 mm and double-sided 200–400 mm. Volume flow rates up to approx. 14,000 m³/h and static pressures up to 1,150 Pa.

Properties & special features

• Compact housing design and high output density
• High number of blades for low acoustic emissions without disruptive blade-tone
• Optimum motor cooling and compact design due to voltage-variable external rotor motor integrated in the impeller
• Housing variants available with discharge flange and fastening brackets

Motor concepts

• AC technology (external rotor motors)

Model examples
Typical variants include RD (double-inlet centrifugal fan) and RG (housing with blue motor).
