Husqvarna 590BFS Left Hand Throttle Gas-Powered Backpack Blower, 1245 CFM

Description

Need extreme blowing force with left-hand frame throttle control? The Husqvarna 590BFS Backpack Blower 970-55-11-01 delivers 1,245 CFM air volume to clear massive commercial acreage. The 79.9cc 5.0HP gas engine generates 54 Newtons blowing thrust, though the left-hand hip throttle requires a few hours of muscle memory adaptation for right-handed operators.

Husqvarna molds the backpack chassis from structural high-density polymer, isolated from the engine block by 4 heavy-duty steel dampening springs. The 79.9cc 2-stroke engine runs at 7,300 RPM to spin the commercial centrifugal impeller. The tool weighs 27.8 lbs dry, occupying a storage space measuring 22in long by 20in wide.

Centrifugal Impeller Thrust Dyno Testing

Bench tests measure 54 Newtons continuous blowing force at 7,300 RPM at the pipe discharge tip. Dynamic pitot tube testing confirms 1,245 CFM air volume at 230 MPH air velocity. Sound meter readings register 78 dB at 50ft distance. Engine cylinder temperatures stabilize at 295°F during full-throttle testing in 86°F shop yard ambient air.

Left Hand Throttle Usability Service Protocol

The frame-mounted throttle lever shifts with 2 lbs of hand force, holding set engine speeds without slipping. Do not buy this machine for indoor facilities, small residential patios, or towns with gas equipment bans. Inspect and clean the primary pleated paper air filter every 25 running hours.
