For the commercial operator, RedMax is easily the industry leader in terms of the selection and performance of power blowers. The EBZ5150 backpack blower features the Strato-Charged 2-stroke engine with ultra-low emissions and high power. With a 50.2 cc displacement and 2.3 horsepower, the EBZ5150 produces a maximum air speed of 171 MPH with tube air flow approaching 487 CFM. The Max Cooled back pad uses air from the fan housing to cool operators and keep them comfortable during hot days. Super wide straps and contoured back pad are oversized for greater comfort. Comes standard with a frame mounted throttle to virtually eliminate downtime due to damaged cables. table { width: 100%; border-collapse: collapse; text-align: center; border: 1px solid black } td, th { border: 1px solid #dddddd; padding: 8px; } Width Weight Height Length 0Inch 227Pounds 0Inch 0Inch
