The 570 and 580 backpack blowers pack a punch, with air speeds of 236 mph and 206 mph and air volume of 770 and 908 cfm respectively. Both frame mounted and tube mounted models are available.
Husqvarna has overcome one of the greatest design challenges of creating more power without adding additional bulk by increasing the efficiency of the fan. Other improvements include the formed back pad to provide the operator with greater comfort for long periods of operation.
Gary Cooler, Husqvarna product manager says “we’ve been able to boost the output of the blower without sacrificing quality or durability.”
Additionally, with Husqvarna’s new large, commercial-grade air filter, the engine can work for longer periods between maintenance. The extra-large fuel tank also allows more time for blowing instead of filling.
The throttle lock allows operator to set throttle speed without maintaining finger pressure on the trigger.
All models come equipped with X-Torq® engine technology that utilizes dual intakes; one for the clean air and one for the fuel-air mixture. First a barrier of clean air presses out the burnt gases, then the fuel-air mixture is flushed in. The result is a more powerful engine, up to 20% reduced fuel consumption and a drop in emissions — of up to 60 percent, compared to conventional two stroke engines.
