Rosenberg USA has introduced a new version of its popular ETRI 148VK AC axial cooling fan. The new 148VK Rev. E features a wider temperature range: (-40°C/+85°C; -40°F/+185°F), the addition of an integrated self-tapping screw on the ground boss to facilitate mounting, and the tropicalization of fan motors.
The 148VK Rev. E is a high-performance fan designed to provide reliable cooling world-wide. Its new construction will accommodate a wide variety of installations. Its expanded range of operating temperatures allows it to operate in very cold or very hot environments. Tropicalization protects the 148VK in climates with high humidity or particularly severe environmental conditions.
The 148VK is built with an aluminum body and a UL 94V-0 plastic impeller. Total weight is just 0.8 kg (1.78 lbs.). The new fans outperform competitive models in airflow by 9% and life expectancy by 33% to 50%.
The ETRI 148V Series includes six models offering airflow from 104 CFM to 252 CFM, compared to 228 CFM maximum for competitive fans. Life expectancy is 80,000 hours at 40˚C, compared to 60,000 or 40,000 hours for lesser competitive fans.
Measuring 172mm x 150 mm x 38 mm, the fans are stackable and feature terminal connections. They are also available with flying leads. Ball bearings are standard. Options include speed sensors, salt spray protection, shock and vibration protection.
Maximum rated noise for the 148VK ranges from a low of 36 dB(A) to a high of just 57 dB(A). Standard models are offered in either 115 or 220VAC, 50 or 60 Hz. They are approved to applicable UL, CE and UKCA standards. Some versions are GAM T1 listed or can be reinforced for non-standard applications. They are also available for 3-phase input power. Thermal protection is standard.
Rosenberg’s ETRI brand fans are recognized as performance leaders in equipment cooling, avionics, marine and railway applications. Accessories include finger guards, filters, and power cords.
