Product Overview

The SENIX 4QL® 49cc Backpack Blower is engineered to provide professional-grade performance in a homeowner-friendly design. Featuring a powerful 49cc, 4-cycle engine, it produces an impressive 425 CFM of airflow at speeds up to 195 MPH, making it highly effective for clearing heavy, wet leaves, grass clippings, and stubborn yard debris.
