Enhance your 40V System with the 40V HP Cordless Backpack Blower Kit. Using 40V HP technology, this backpack blower delivers more power than a 51cc gas blower, making it a true gas replacement. The HP Backpack Blower delivers up to 52 minutes of runtime with the included (2) 40V 6Ah lithium batteries. 40V HP technology combines a brushless motor, advanced electronics and high-performance lithium technology, to easily tackle wet leaves and heavier lawn debris with 730 CFM and 165 MPH. That is gas performance with just the pull of a trigger. No gas, no maintenance, no hassle. Designed with noise dampening foam, this Whisper Series blower is engineered to be 85% quieter than gas and even other cordless blowers, so you can work anytime without disturbing others. A variable speed trigger and turbo button allow you to control the output of air so you can dial back when in delicate areas like blowing leaves from mulch beds and engage the turbo button when clearing tougher debris. Add on the customizable speed tip for increased air speed. Best of all, it is part of the RYOBI 40V System where any 40V battery works with any 40V product. This 40V HP Blower kit is backed by the RYOBI 5-year manufacturer’s warranty and 3-year manufacturer’s battery warranty.
