CUI has introduced its CFM-V line of DC axial fans that boasts superior performance and reliability compared to conventional sleeve bearing fans, thanks to its innovative omniCOOL system. This advanced bearing design bridges the cost-performance gap between traditional sleeve and ball bearing fan technologies. Incorporating a magnetic structure that enables rotor-balancing to minimize tilt, wobble, and friction, the omniCOOL system allows for fan operation at any angle. It also reduces the need for lubricant, further decreasing fan noise and friction. In addition, the bearing system extends operational life by utilizing a specially hardened material that provides additional heat resistance and offers protection against any abrasion that may occur. The series with frame sizes from 40mm to 120mm delivers airflows ranging from 5.4CFM to 10.8CFM in the 40mm series up to 138CFM in the 120mm series. Available with rated voltages of 5VDC, 12VDC, 24VDC, and 48VDC, all axial fans come as standard with auto restart protection and feature options for tachometer signal and rotation detector depending on the model. Static pressure values range from 0.04” up to 0.41” H2O with low rated currents from 26mA to 958mA. All models in the series carry UL/cUL 507 and TUV EN 60950-1 safety approvals while complying with EN 61000-6-1:2007 limits for EMI/EMC. With typical MTBF ratings of 70,000 hours at40C and multiple speed options ranging from 1700RPM to 8500RPM, the company’s line of DC axial fans with the omniCOOL system provide the ideal mix of economy and performance for a variety of cooling needs, including tel ecommunications equipment, medical devices, and industrial applications.
