Cordless jobsite fans supply a personal, portable cooling source that runs on power tool batteries and delivers targeted airflow that keeps workers cool and reduces their risk of heat stress in hot conditions. They eliminate the tripping hazard of a cord, operate in areas without wired power or nearby outlets, and use brand-specific batteries, which can power other tools of the same brand. Their head tilts to direct airflow, and their speed control adjusts the air output. These jobsite fans resist impacts and are lightweight with a carrying handle that eases transport between locations. A guard encloses the fan blades to help protect them from damage and prevent injuries from accidental contact.
