For the commercial operator, RedMax is easily the industry leader in terms of the selection and performance of power blowers. The EBZ7100-RH backpack blower features the Strato-Charged 2-stroke engine with ultra-low emissions and high power. With a 64.9 cc displacement and 3.9 horsepower, the EBZ7100-RH produces a maximum air speed of 205 MPH with tube air flow approaching 586 CFM. The Max Cooled back pad uses air from the fan housing to cool operators and keep them comfortable during hot days. Tube mounted throttle allows the operator to easily adjust air flow from gentle breeze to hurricane force.
