Rosenberg D-Series: new design for backward-curved fan housing boosts efficiency, reduces HVAC noise.
2024-03-26
Rosenberg’s new D-Series efficiency-boosting airflow guide housing, designed specifically for Rosenberg I-series impellers, increases efficiency by an additional 12+%. In normal operation of a 560-mm backward curved fan, this added efficiency can result in nearly $800 in energy savings per year. The guide housing also reduces fan noise by up to 4 dB, making it an excellent choice for air handling units.
