Special bearings let dc axial fans operate at any angle

October 4, 2017 By Lee Teschler

The CFM-V line of dc axial fans incorporates an innovative omniCOOL system. 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 reducing 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 120 mm delivers airflows ranging CUI CFM-V linefrom 5.4 to 10.8 CFM in the 40-mm 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 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.

With typical MTBF ratings of 70,000 hours at 40°C and multiple speed options ranging from 1,700 to 8,500 RPM, CUI’s line of dc axial fans with the omniCOOL system provide a mix of economy and performance for a variety of cooling needs, including telecommunications equipment, medical devices, and industrial applications.

The CFM-V series is available immediately with prices starting at $3.40 per unit at 100 pieces through distribution.
