RIDGID introduces the R860721 18V Cordless Hybrid Jobsite Fan (Tool Only). The new Hybrid Jobsite Fan is 40% more powerful than the predecessor model R860720, with impressive air movement speeds of 670 CFM and 1070 FPM. Even with such high-power, the fan maintains quiet noise levels with a decibel level of less than 50 dBA. Using an 18V 6.0Ah MAX Output Battery (R840060), this fan can deliver over 7 hours of runtime on the max speed setting. The hybrid feature on the 18V Hybrid Jobsite Fan allows the fan to run on any RIDGID 18V battery or an extension cord to keep the fan running even longer. Using the integrated extension cord slot, the cord can be tucked flat under the unit while plugged in. For maximum usability and convenience, the fan offers 10 different mounting options. As always, the RIDGID 18V Hybrid Jobsite Fan is 100% compatible with all RIDGID 18V batteries. The R8609021 fan includes the Hybrid Jobsite Fan and Operator's Manual. Batteries and charger sold separately.
