Re: Nordfab rigid metal flex duct question #dustcollection
¿ªÔÆÌåÓýHere are a few pics of the mess.? The pipe will go up from the right side of the pics, follow the ceiling until a horizontal can clear the HVAC duct and go to the other side.? A branch will run each way along the left side of the I-Beam to the far wall where the RAS is, to the jointer and planer location, and then back the other way to the sander. Another branch will follow the ceiling back down the other side to the saw/shaper and to other machines on? that side of the room.? The angle from the wall to the ceiling is 106 degrees. ? I can use a standard 90 at the collector and not have the vertical pipe be plumb.? My engineer and builder OCD eye would not love that but I could live with it. Where I transition from going vertical to horizontal near the ridge beam, I need slight bend (16 degrees) on each end.? I played with double elbows to get custom angles but that changes the pipe angles to the ceiling and it looks like the cost of two standard elbows and clamps is more than a custom angle and clamps. ? ?

It¡¯s not like that, the way it will be laid out.? Because of overhead doors and the footprint of the shop the collector is on one side next to a 9 ft wall and I need to run the duct up the vault to the ridge.? Once there I can use standard parts.? The roof plane ?is 108.4 degrees to the side wall. Once running up the roof plane I need to get back to horizontal below the ridge beam which extends about 10¡± below the ceiling. ?

On Behalf Of Brian Lamb ? I assume you are running the main branch down the middle at the peak of the ceiling? Standard Y¡¯s should get the branch running down the slope of the ceiling, it¡¯s when you want to come off the slop and have a vertical run of pipe that the issue comes in, correct? Seems like a combination of two 45¡¯s or 90¡¯s at that point will get you any angle you want without resorting to custom fittings. I use spiral pipe and long sweep fittings, and have been known to cut one where I need to get whatever angle I want, then you rivet the short Nordfab rolled edge piece so you can clamp it to your other parts. ? I have a lot of Nordfab ¡°joiner¡± pieces adapted to my spiral pipe to act like quick changes.
