Husqvarna 356BT 52cc 2-Cycle, Low Noise Backpack Blower
If you value quiet operation above all else, than the Husqvarna 356BT 52cc 2-Cycle, Low Noise Backpack Blower is what you'll need. This is literally the quietest blower on our list due to a specially engineered exhaust and noise-dampening housing making it a great choice for early weekend mornings. It's no slouch in the blowing department either at 177 mph while an air purge button allows easy starting of the engine.
A centrifugal air injection system keeps dust and dirt out of the carburetor, and it’s also one of the more fuel efficient blowers available. Although it weighs almost 23 pounds, this backpack blower has an adjustable handle and padded shoulder and hip straps for operator comfort. It comes protected by a two year warranty and while not inexpensive, this is the blower to get if you want relative peace and quiet.
