This adapter can be used with rigid, semi-rigid or flex duct. This product enables the Dayton Blower 6FHX9 to be vented using standard 4' inch diameter circular duct. This is when we realized that we could add value if we made this adapter commercially available. After much research we came to the conclusion that there were no adapters commercially available that would properly transition from the square flange of the blower to a round duct outlet. People started asking us where to get an adapter, so we started looking for an adapter that would work. When we built our spray booth we created our own square to round adapter. We used 24 gauge galvanized steel for the fan mount panel so that we could have top or bottom discharge just by flipping the panel. We externally mounted the blower so the motor windings would not be damaged by harmful paint and solvents. This process is extremely simple, it's literally just 3 wires 1 positive, 1 negative and 1 ground. Don't worry you won't need any prior experience or knowledge of electricity to cord the blower.

These types of blowers do not come corded so you will have to get a grounded power cord and cord it yourself.
