Milwaukee 0820-20 M12 12 Volt Lithium Ion Cordless Mounting Fan, Tool Only

Milwaukee 0820-20 M12 12 Volt Lithium-Ion Cordless Mounting Fan – Tool Only

The Milwaukee 0820-20 M12 12 Volt Lithium-Ion Cordless Mounting Fan is designed to deliver portable airflow for cooling, drying, and ventilation in work areas where corded fans are less practical. Built with a 6 inch blade, this cordless fan produces air speed up to 14 MPH and airflow up to 400 CFM, giving users a compact but effective option for moving air around jobsites, workshops, service vehicles, and maintenance areas. Its cordless design makes it easy to place where airflow is needed most without relying on nearby outlets or extension cords.

This Milwaukee jobsite fan is built for flexibility as much as airflow. It features integrated magnets, a 2 inch spring-loaded clamp, keyholes, and pass-through holes so it can be mounted in a variety of ways on framing, ladders, carts, shelves, and other work surfaces. The 360 degree rotating head allows users to direct air exactly where it is needed, while three speed settings provide better control for different tasks and environments. Compatible with all M12 batteries, this battery powered fan is a practical solution for professionals and advanced DIY users who need a portable fan for indoor or outdoor use. Batteries and charger are sold separately.
