Default Anyone using a 6" vortex inline with a 4" reducer?

I was all set to start ducting. My plan was to use a 6" inline vortex fan with a 6" to 4" reducer right at output side of the fan that will be attached to 4" PVC pipe.

I was planning to use 6" ducting elbow from the fan to the hood.

Then the HD guy told me that I was loose too many CFM reducing to 4"

Anyone else doing this? Will I loose too much CFM reducing to 4" form 6"?

6" PVC is not at the big box stores and its kind of... big....

here is a link to a picture in my build thread. http://www.homebrewtalk.com/f170/just-another-electric-brewery-build-thread-317746/index2.html#post3978218

I recommend checking out this site:

http://www.freecalc.com/ductloss.htm

This will let you enter your duct length / size and the number of reducers and elbows and it will tell you how much loss you'll have.

Stick with 6 if you can. 4" will halve your flow rate. Have you looked into metal ducting?

I have but then I gotta buy crimping tool and cutter which looked like $75 bucks! Looks like I'll just have to suck it up.

Self-tapping screws, tin snips and some aluminum tape should be all you need. I've only worked with it replacing my cooktop so may be wrong.

I think you can get pre-crimped on one side if you don't have to run it too far.
