Suction Penalty With Baffle?

[Crow Horse]

I'm still tweaking/shaking down the 2 separators I've made, but with both I've found that there is a slight suction penalty which doesn't make sense to me.  The penalty is small yet perceptible.  Any ideas as why this occurs?

Chuck,
I've used the separator both with and without the baffle, everything else remaining the same.  There is a slight decrease in suction.  Nothing drastic, yet it's perceptible.  Doesn't make sense.  Beats the hell out of me.....

The small fitting in the center is to match the hose I'm using (1 1/4"). The setup is used around my shop desk, generally for basic cleanups as well as the mess my dogs manage to bring in (as well as myself).....

Interesting point.  I suppose the bottom line is "it is what it is", at least for now.  I did have the fore thought to make the internal fitting in such a manner that I can easily change it out if needed.  Maybe when all the other items are taken care of I'll address that issue.  Thanks for the insight.....

I'm a hopeless tinkerer as well.  Most times I try to improve an existing product usually trying to reinvent the wheel.  Sometimes I get bit in the ass and other times I hit a home run.  The law of averages usually dominates....

I'm really pleased with the screw on lid.  It did solve one problem but it created a couple of other minor obstacles but they were fairly easy to overcome.....

I am the same, I have invented a lot of wheels in my time. You would laugh at some of the CAD drawings that I have put together on this subject. But if you don't at least start with the basic design, you will never know if you have an improvement. I haven't built anything yet, but will be setting aside some time soon.

Good luck with your project.

I'm just starting to learn "Sketchup".  I'm being generous to myself by using the term "learn".  If I can master that, it holds great promise in being a valuable tool in my arsenal.......

The beauty of CAD is that once a part is drawn, you can empty the design from your head. If a design has more than 3 or 4 parts, I have great difficulty keeping all the plates spinning in my head. Also the 3D visibility helps you ?see? the problems before you start cutting.

I use Catia V5 in my day job, but can still remember the drawing board days. Ironically, I failed technical drawing twice in school and ended up doing it for a living. The problem with CAD is that you need to use it fairly regularly, otherwise it is like learning from scratch every time you need it.
