The power of hurricane force winds-yet easy on the ears. The "Q" stands for quiet because the QB blowers have had the industry's lowest noise levels for the last ten years. They're loaded with professional features like our exclusive, lightweight 14-blade fan that eliminates the tiresome "gyro" effect; a proprietary curved radius housing that reduces air turbulence and provides unparalleled strength; shock isolation mounts to reduce irritating vibration; pneumatic front and rear wheels (N/A on QB553HC) with grease zerks; commercial-duty throttle, and a unique foot-operated deflector. We challenge you to find any blower with as much value or better weight-to-performance ratio than the one and only Quiet Blow!
