The 800 cfm ~ 12-amp Electric Turbine Blower is, quite simply, the most powerful electric blower in the marketplace. Other 800 cfm (Cubic Feet per Minute) blowers don~t put out wind power at 135 mph. Physics shouldn~t allow it, but our engineers found a workaround. And even though you~re going to want to blow at that speed all the time, you can use the variable speed control to dial it down. When you need even more power than the 800 cfm/135 mph can provide, there~s the Hyper-Stream nozzle that focuses all the airflow right where you need it. Believe it or not, all that power can be controlled with one hand. The whole unit is only 6.6 lbs., and that amazing Turbine tech creates a wind tunnel that is easy to point. The cord retainer keeps extension cords from pulling apart, even on snags. And you don~t need any tools to put it together. Time to go clear that lawn.
