Model DUB362 has been developed as the most powerful cordless blower, which outperforms competing models. Key Reasons to Go Brushless Brushless motor draws less amps works twice as long. Less heat generation extends battery life reduces frequency of charging batteries. Makita s brushless motor enhances operational performance as well as battery longevity. Less friction increases motor speed and less heat is generated which improves performance and extends machine life. Other features include: Powered by two 18V Li-ion batteries in series to supply energy to the powerful 36V DC motor drive system. Dual battery fuel gauge. High air volume and speed delivered by brushless motor. Longer run time thanks to brushless motor. 6-stage air volume/velocity settings by dial with variable.
