Keeping Quiet

sunnydog · Jul 10, 2008

Have a way to quiet things down.
Just installed a vortex 8" blower in my cab.
Got the blower in a rubbermaid silenced by inch thick solid rubber( it's some stuff used to line horse stalls with,VERY HEAVY,VERY DENSE) and fiber glass insulation.
It runs REAL QUIET now.
However, the AIR rushing through the insulated flexi hose STILL made way to much noise for me.
SO...... What I did was run the 8" hose inside of 10" ins. hose and achieved near silence! Some what pricey option, but is working real well for me.
Hope this helps somebody.

Do you mean you slipped the 10" hose over the whole 8" run, like a really thick hose? Or do you mean you used the 10" as a muffler at the end of the run?

Slid it over, doubles the insulation.
I found the entire hose was giving off noise.
Seems to be a 50-75% improvement.
My wife agrees!

Nice. I had used the cheap, thin blue pipe insulation to wrap my hosing before. It probably cut a half db off the top. I'll have to try your method. Did you use insulated or just plain flex?

Can anyone shed some light on acoustic ducting?
Its a lil bit more per meter,is anyone usuing it?

8bitNES · Jul 10, 2008

Is acoustic ducting different than insulated? If they're the same then considerably more than regular ducting, as far as hose pricing is concerned. Its not like 5x more. If acoustic differs from insulated I'd think that acoustic would cost more since in most cases things labeled acoustic come with heavy price tags.

Insulated ducting has fiberglass-like padding sandwiched between 2 layers of whatever the plastic duct is made of. Basically regular hose wrapped in insulation and wrapped again in the plastic material.

Its does have insulation,but its being sold as acoustic so I recon the insulation maybe be differant,ill have to check that next time im at the store.

Hi, D.H. No, both already have insulation. They make a pretty nice fit together.
6" into 10" is looser fit but works real well,also.
It seems they will match up in 2" increments, ie,4 into 6, 6 into 8, 8 into 10, etc. Space accomadates the insulation jacket.
A bit bulky,but still more neat and tidy than wrapping duct with blankets,etc. and MUCH quieter!

Has anyone measured the db level before and after on those vortex fans? Raistlin - Great books

Nice rig.

Sunnydog - Thank you for this thread.

Thanks for the thanks!
I just tried this today for the first time.
Don't know how many db's. but it is a pretty big improvement.
If my "grow area" was away from my "live area" I probably would not care so much, this just helps make things more livable.

Does the fan get hot at all? I've got some squirell cage fans that kind of make me paranoid (hot as some ballasts)...looking to replace them.

No,not at all.
Hot fans would freak me out. I think I would replace those,ASAP.
I've used those in the past, I do not remember them getting so hot, airflow should cool the motor.
My :2cents:

Pretty much same as mine, what I did was encircled the fan with 1" rubber sound deadner, wrapped with bungee cords, this shit weighs a ton! then stuffed the rest with glasswool insulation.
Fan is BARELY AUDIBLE.

I used a rubbermaid, put a pillow in the bottom, a blanket around the fan, and a pillow on the top. Then a lid.

Seemed to work out pretty good.

Thank you so much as soon as home depot opens up I am buying 10" so I can wrap all my 8" double over I can hear so much noise actually coming through the ducting even with the insulation and i remember what a difference it was going from normal 8" to big old insulated ducting. Only makes sense that doubling it up would make double the difference. I also hear a fair amount escaping from my 5ft tall carbon filter.
