The Husqvarna 145BT backpack blower is lightweight, not too loud, and packs a good deal of power. The 40 cc engine offers 2.7 hp. This blower moves air at 311 cfm and a speed of 175 mph at the tube. The sound level per ANSI B175.2 standards is 75 dB(A), so make sure to wear your ear protection. The high velocity of air flow allows the operator to quickly handle leaves, grass, and other debris. The ergonomic design of the 145BT is focused on comfort. The padded backing, hip pad, and backpack straps make this 19.4 pound blower a breeze to handle. The two cycle engine starts easily due to the handy air purge, and the RPMs are controlled via a trigger throttle mounted on the tube. The large 1.6 liter see through fuel tank will allow the operator to spend more time moving debris, and less time refilling the tank.
