Just as the name suggests, HART’s 20V 4" Clamp Fan comes built with a clamp that allows you to attach it to unusual places such as the edge of a desk, the frame of a treadmill, the hood of a car or even a small pipe under the sink. This fan is the perfect addition to any outdoor enthusiast’s collection. Whether camping in the woods, or relaxing on the beach, this fan provides personal cordless cooling with a clamp that can be mounted virtually anywhere. In fact, the clamp attaches to any material up to 1-1/2” thick, including a 2-by-4 —perfect for picnic tables, sporting events, and lazy days at the beach. Designed to be self-standing, it provides over 180 CFM of airflow while its rotating and tilting head allows you to direct the cool air precisely where you want it to go. And, yes, the 20V battery and charger are sold separately, but the good news is this 20V fan works with all HART 20V batteries. Just swap out the battery from another 20V HART tool and you’re in business. Includes: fan and operator’s manual.
