Ecofit-brand high-efficiency E-Wheel backward-curved impellers are now available from Rosenberg USA in the popular 192-mm (7.5-in) size. Available in both 115V (PN U24- A4) and 230V (PN U24-B1) models, the new impellers improve the ventilation efficiency and save energy while reducing operating noise. They replace Ecofit PN C10-A6 (115V) and PN J47-A5 (230V).

Ecofit E-Wheel fans feature special airfoil blades made from UL 94 V-0 reinforced plastic. Their unique design allows for airflow of 187 CFM at 1.2-inches of static pressure with an operating noise level of just 60 dB(A) in the 115V models. The 230V models offer 234 CFM with only 56 dB(A) at .8 inches. Maximum airflow is 421 CFM (115V) and 347 (230V) at free air.

The single-phase AC motors for the new fans are CE approved and UL recognized. They are built with standard Class F insulation and Type 2 ball bearings.

Ecofit E-Wheel fans offer smart solutions for many ventilation applications, including air filtration, HVAC, cooling and thermal management.
