Sizes Added to Backward-Curved Impeller Line

Rosenberg has recently expanded its high-efficiency E-Series backward-curved impellers to now include sizes from 12.4 to 22 inches with either AC or EC motors.

The unique airfoil blade impeller increases energy efficiency by up to 4% and reduces noise by 3 to 5 dB(A).

Recommended for computer room air conditioning and air handling (CRAC/CRAH), or energy recovery.
