Long and short ducts are included and can be configured 16 different ways for efficient airflow.

The 60155 cooling fan is powered by a detachable, rechargeable lithium-ion battery that can also charge other small USB devices such as headlamps, phones, worksite speakers and more. The cooling fan and battery module include accessory mounts for work lamps and/or safety lights (sold separately).
