The Makita 36V Lithium-Ion Lithium-Ion Cordless Blower (model UB360DWB) has a variable 2-speed motor (0-10,000, 0-17,000 RPM) for optimum speed control and a maximum air velocity of 208 MPH with up to 30 minutes of continuous run time on a single charge. Added benefits include lower noise at only 86 dB(A) and zero emissions, making it ideal for applications in residential areas. The UB360DWB requires none of the maintenance associated with comparable gas-powered blowers: simply insert a charged 36V Lithium-Ion battery and the tool is ready for work.
