AHR Expo and its co-sponsors, ASHRAE and AHRI, have chosen the
Rosenberg I-Series Backward Curved Fan as the WINNER in the
Ventilation Category of the 2025 AHR Innovation Awards.
CHARLOTTE, N.C., Dec. 2, 2024
/PRNewswire-PRWeb/ -- The award-winning Rosenberg I-Series
impeller EC fan increases airflow and energy efficiency, while
greatly reducing noise. The I-impeller design features five
backward-curved, hollow-profiled, airfoil section aluminum blades,
with an efficiency-optimized circumferential diffuser. Depending on
fan size and operating point, the new impeller boosts efficiency by
up to 11% and cuts noise levels by more than half compared to older
impellers.
The new design significantly reduces the
turbulent downstream air produced by traditional backward-curved
impellers. The effect of this reduction is to significantly reduce
noise and increase in-application efficiency.
I-Series blades are positioned diagonally and top-flared so that
airflow direction is optimized for the highest efficiency and flow
rates. The new design significantly reduces the turbulent
downstream air produced by traditional backward-curved impellers.
The effect of this reduction is to significantly reduce noise and
increase in-application efficiency.
The I-impeller is statically and dynamically balanced according
to DIN ISO 21940. Noise levels range from a high of just 89 dB to a
low of 68 dB while moving up to 12% more air than earlier
models.
I-Series fans are available with Rosenberg Gen3 and Gen3+ EC
motors operating at up to 7.2 kW of power input. All I-Series fans
are AMCA Certified for sound and air movement performance.
