HOW FAR BEYOND THE EDGE OF THE HOUSING DOES THE AIR SPREAD AND WHAT IS THE DEPTH?
The air leaves the discharge nozzle at very high velocities. The air spread and depth of “air wall” created varies between models. A general rule of thumb is: for units with 1HP motor(s) or less, the air spread is up to 3″ and the depth of the wall of air created is about 18″, measured 6’ from the nozzle. For units with motor(s) larger than 1HP, the air spread is up to 6″ and the depth of the wall of air is about 24″, measured 6’ from the nozzle.
