For the commercial operator, RedMax is easily the industry leader in terms of the selection and performance of power blowers. The EBZ8100-RH is our most powerful backpack blower and features the Strato-Charged 2-stroke engine with ultra-low emissions and high power. With a 71.9 cc displacement and 4.4 horsepower, the EBZ8100-RH produces a maximum air speed of 201 MPH with tube air flow approaching 685 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 control allows the operator to easily adjust air flow from gentle breeze to hurricane force.
