With no carbon brushes, the Makita® BL™ Brushless motor runs cooler and more efficiently for longer life, and delivers speeds up to 116 MPH air velocity and a full 459 CFM. Makita’s efficient BL™ Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per battery charge than similar non-brushless tools. Electronic controls efficiently use battery energy to match the changing demands of the application for increased power and speed when needed. A cruise control lever provides management of power and run time.
