Hi Joe -- What is the best measure of a leafblower's power? I am trying to understand why the Husqvarana 350BT is considered more powerful than the 150BT because it appears that the 150BT and the 350BT have the same CFM (494) but the 150BT has a higher air speed than the 350BT. I understand that the 350BT is more durable but I cannot understand why it would be considered more powerful than the 150BT. Thanks.

Quan,
You, my friend, win the perceptive shopper award today. You chose such a fine example too. On paper, the Husqvarna 150BT and the 350BT appear remarkable similar. All of the specifics matching up across the board. Except for that pesky air speed. You may hear a lot of people talk about how important that air speed is, and they are partially correct. Air speed is a direct measure of engine size and power. But the true measure of a good leaf blower is shown by what will move your debris...Air Volume or CFMs.
In the case of the Husqvarna 150 vs. 350, you will see that the 350BT has a more commercial design allowing a similar size engine to work less to achieve the same air volume. This leads to longer run times with less engine wear.
