The Battery Powered Personal Air Conditioner

I found a few fans which are perfect for an office. Because of the small size you can place them anywhere you want.

I recommend it because it delivers a powerful stream of air up to 27 feet, and its adjustable-tilt head pivots for directing airflow where it's needed most. Use the fan on its own as an air circulator all year long or in addition to an air-conditioning or heating system to help save energy and reduce utility costs. Other highlights include a removable grill for quick cleaning, a lightweight design for simple transport from room to room, and a wall-mounting option to help save on space.

This sturdy, attractive fan clips to most surfaces, and its streamline design is ideal for tight spaces. The unit pivots on two different axes (one at the fan base and one at the clip mechanism) and can bend over 180 degrees at the juncture connecting the fan and clip.
