The Best Velocity for Moving Air Through Ducts | Energy Vanguard
Jun 26, 2019 · The first thing to know about the velocity of air moving through ducts is that the slower you get the air moving, the better it is for air flow. That was the main point of my last article. In fact, the title asked the question, "Is Low Velocity Bad for Air Flow in Ducts?” And the answer was that, in terms of air flow, you really can’t get the air moving through the ducts too slowly.Learn More
