This fan easily attaches to columns or poles with included mounting bracket. It has an efficient three-speed open-air over PSC-type ball bearing motor that is permanently lubricated. Quiet metal fan blades are balanced for optimum air distribution and enclosed in steel wire guards for safety with a safety-clutch oscillating mechanism that prevents jamming. A simple push button gives you the option to keep the head fixed in one direction or 70° oscillating operation with the ability to tilt it for perfect air-flow placement. Pull chain on/off.
