Dust Collection Question

Hi All,

I've enjoyed lurking on the forum for several years, and continue to be impressed with the amount of knowledge shared. I have a question, that may end up in more opinions than answers, but thought I'd try. I've just reconfigured my Harbor Freight dust collector to incorporate the Oneida SDD, and a Wynn filter. I'm pleased with the performance, and overall setup. I modeled my setup after a recent posting I saw here. I have a 10' section of 4" flex hose that I'm able to use for most of my machines. I also have a 8' or so section of 5" flex hose left over…..what I'm wondering is if it's worth it to use the 8' section of 5" and then attach a 1-2' section of 4" to attach to my machine ports. I realize I could just go buy a 5-4" reducer, and try it myself, but I'd rather not buy another fitting if it's not worth the bother, not to mention the 5" hose section is more cumbersome to tote around. Thoughts?

Thanks,

I think you'll be fine with the 4" hose. I use that throughout my shop. I just picked up some 5" hose because the 5"-4" reducer won't fit the 5" ports on my new machines and I needed a bit more hose.

The SDD has a 5" inlet so you already have the reducer if you're using a 4" hose. It will make a difference but not much, maybe a 3% or so increase in flow.
