For the commercial operator, RedMax is easily the industry leader in terms of the selection and performance of power blowers. The EBZ7500 backpack blower features the Strato-Charged 2-stroke engine with ultra-low emissions and high power. With a 65.6 cc displacement and 3.9 horsepower, the EBZ7500 produces a maximum air speed of 236 MPH with tube air flow approaching 770 CFM. The Max Cooled back pad uses air sucked by the fan housing to cool operators and keep them comfortable during hot days. Wide straps and contoured back pad are oversized for greater comfort.
