Hi! This is Rick Pedley, and welcome to PK Safety Supply!
Today I'm going to be talking about the Ecko brand K0805. This is a confined space blower that is 8 inches in diameter. It has a metal housing, a grab handle on the top and pushes air in one direction. That is, this direction. So if you want to push or pull, you just flip it one way or the other. There's no switch on this. It's an economy-minded product, so plug it in, it's gonna go.
It's gonna move 880 cubic feet per minute in what we call "free air," that is, without ducting. When we add a duct, that adds some amount of friction, so it does reduce the amount of airflow. Adding a 90-degree bend further reduces this. For example, a 20-foot house with one 90-degree bend reduces it to 672 cubic feet per minute. Still, a fair amount, but this is for a relatively small confined space.
It comes with a 12-foot cord, a three-prong connector on the end. This has a one quarter horse power motor, and what's kind of neat about the way they make the Ecko fans is the cast aluminum impeller, or fan, inside. This allows it to move much more air than a simple four-bladed fan on some less expensive models I've seen on the market.
The way you use this is with ducting. The eight-inch ducting is available in either 13 or 25 feet. The ends are the same on either one. A helical coil spring, double-coated PVC on nylon and a belt strap. And the way this works is that we just slide it on. No more to it than that. Very easy, and once it's on the fan, we just tighten it up and that's all there is to it.
We then take this cord, plug it into our outlet and the fan's good to go. It does make some noise, no doubt about it, but it's pushing a lot of air. Volume, not pressure. It's very important to understand the difference between those two.
