Milwaukee 0821-20 Brushless 18 Inch M18 Job Site Fan

Product Description

The Milwaukee Electric Tool Corp 0821-20 is an 18-inch brushless job site fan built for the M18 battery platform. The brushless motor drives an 18-inch blade that moves air over 50 feet at speeds up to 13.5 MPH, delivering ventilation, cooling, and drying performance comparable to corded units. A reinforced metal base and shroud provide impact, water, and dust resistance for demanding job site conditions. The integrated AC plug allows connection to a standard extension cord when battery runtime is not practical. Electricians, HVAC techs, plumbers, and general contractors use this fan during active work and post-service drying operations.

The 0821-20 is designed for job site use where portable, high-volume air movement is required. It suits both residential and light commercial applications including crawl space ventilation, attic work, post-flood drying, paint and adhesive curing, and general crew comfort during hot-weather service calls. The fan operates on any M18 battery pack. Runtime up to 5 hours on the high setting is achievable with the M18 HD12.0 battery pack. The interlocking stackable design supports efficient transport and storage in service vehicles.
