Dc axial fans deliver improved life and performance

CUI’s Thermal Management Group has unveiled the CFM-V line of dc axial fans offering improved performance and reliability compared to conventional sleeve bearing fans.

Using the company’s omniCOOL system the device is intended to bridge the cost-performance gap between traditional sleeve and ball bearing fan technologies.

Incorporating a magnetic structure that enables rotor-balancing to reduce 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 CFM-V series with frame sizes from 40 to 120mm delivers airflows ranging from 5.4 to 10.8 CFM in the 40mm series up to 138 CFM in the 120 mm series.

Available with rated voltages of 5, 12, 24, and 48 Vdc, 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 inch H2O with low rated currents from 26 to 958 mA.

All models in the CFM-V series also carry UL/cUL 507 and TUV EN 60950-1 safety approvals while complying with EN 61000-6-1:2007 limits for EMI/EMC.
