The EGO POWER+ 600 CFM Backpack Blower is up to 60* times quieter and weighs half as much as comparable gas blowers. Turbine-fan engineering moves air at a staggering 600 CFM. Variable-speed control allows you to dial the power up or down for superior control, from 260 cubic feet per minute to 600 cubic feet per minute, and the turbo button gives you max power for heavy-debris-clearing power. The Backpack Blower’s high-efficiency brushless motor delivers longer run time, low vibrations and an extended motor life. The advanced EGO POWER+ 56V battery uses industry-leading ARC Lithium? technology to deliver Power Beyond Belief and is compatible with all EGO POWER+ products.
