Rosenberg USA is introducing more new ETRI cooling fans to the U.S. market. The new 125D-A DC 120x120x38 mm axial fan family delivers higher airflow with no increase in noise thanks to its saber-shaped winglet blade design.

The new fans also feature a long-life brushless DC motor available with 12, 24 or 48 VDC input for a wide range of product applications, including circuit board cooling, semi-conductor cooling or motor cooling. The 125D-A range provides airflow from 57 to 163 CFM, speeds from 1695 to 4835 RPM with low operating noise from just 30 to 54 dB(A).

Like all ETRI fans, the new 125D-A is highly reliable. L10 life expectancy is 80,000 hours at 40 degrees C (104 degrees F). The operating temperature range is -20 to +70 degrees C (-4 to 158 degrees F).

The housing and impeller of the 125D-A are made from UL 94 V-0 plastic.  Weight is less than 12 ounces. It is CE-approved and RoHS compliant. Options include speed sensor, alarm and special construction to withstand salt spray, dry cold, wet heat, shock and vibration.
