I make sure all my machines stay in top working order but pay little attention to the dust collectors, other than emptying the bags and cleaning the filters. Reading stuff about them here has kind of inspired me to do better.

Both my Grizzly 2hp and Jet 1100 have the 5” flexible tubing from the fan to the filter/bags. I know if I would have spent more money the collectors have solid metal tubing. Is it possible and is it worth the effort to change the flex to solid of some type? I’m not even sure if anything is available to do this. The Jet has the cartridge filter and the Grizzly a bag. I converted the Jet to 220V and I’m thinking about getting a cartridge for the Grizzly, which may help.

I have the machines in opposite corners with about 20’ of flex tubing running down a wall. I use y’s and blast gates to connect to my different machines. I’m thinking about changing the long run of tubing to solid plastic pipe but will still have use flex to connect to my various machines as some have to be moved to use. Would this be worth the effort?

Any advice is appreciated.

I don’t know if those short pieces of flex between the impellers and bag housings make a lot of difference, but 20’ of flex sure can.

The mantras of dust collection piping are (1) The shortest runs possible; (2) The fewest bends possible (and sweeps instead of elbows); (3) The smoothest interior walls possible; and (4) Well sealed joints (and seams if you use HVAC ducting)

I run a Jet 1100 with 4” sheet metal ducting. All the duct joints and seams are covered with electrical tape, and I only use flex duct to connect my tools to the metal duct. I’m giving serious thought to removing the “Y” at the impeller housing and going to 6” sheet metal ducting with 4” drops to the machines. I get pretty good collection now, and should get better collection by going to 6” ducting.
