bad idea to put vortex fan in attic?

so i got a 6" vortex that was in my grow room before but i wanted to clean the room up and dont really have the space for the vortex. i can move the fan to the attic (right above) which would be easy enough to do, just concerned that i may decrease performance or have some issues.

benefit i think would be less noise and probably a cleaner grow room which would make it easier to work in, negative may be lose of air flow.

should i be concerned or just put it up there?

inline fans are intended to mount out of sight, often in the attic. Make sure that you secure it to a sturdy beam, or hang it from chains and attach the ducts with gorilla tape and duct clamps to make a dependable connection. With some basic wiring skills you can shut off power and wire the fan into your 120 power pretty easily or run a long extension cord into the house.

I helped set up a friend and put the 12" Elicent in the attic...works perfect. Doesn't really matter if you put in the room or attic regarding effectiveness IF you basically have the same length of ducting in each possible installation. Duct length increases resistance...thus reducing effectiveness.

Sounds like 6 of 1 or half dozen of another.

My only concern would be, "Out of sight out of mind." Inlines do require some small bit of maintenance. Usually no more than a yearly inspection and a drop of oil. Set it up somewhere you can get to it easily.

My 4", quadruple muffled, was audible across the street to my neighbor's door. But, only with the garage door open. With garage doors closed, there was no noise inside the house or outside the garage. Removing the fan from the growroom to one where no one is allowed to go is a great move.

WHAT? Inline fans don't need a drop of oil ever...maybe the blades need to be cleaned of dust/fuzz buildup but that's it. One reason I used Elicent's more often than Vortex was the noise factor. IME a 6" Elicent is quieter than a 4" Vortex.
Ball bearing motor, permanently lubricated, fan and motor assembly balanced for quiet and vibration-free operation
I dunno...had great success muffling a 6" Vortex using a home made duct muffler out of a stove pipe and lined with cheap foam on top of a cardboard box lined with 'acoustic' foam. The fan was like 6' below the opening and the Vortex 'whine' was totally gone.

well i would be increasing duct length but about 5-6 feet about, the fan would pretty much be right on the other side of the drywall.

looks like i will be climbing up into the attic heh. i found the original mounts i believe to the vortex, not to sure, look like just angle iron, i believe they mount to the sets of 3 screws on either side?

not gonna do any crazy wiring, just extension cord it.

5-6' extra is nothing really for a 6"...the 12" Elicent I mentioned ran off an extension. Hang the fan from bungees and do not directly mount on anything...that right there will virtually eliminate any vibration/low frequency sound stuff transmitting through the walls.

LOL...I've climbed into attics, under houses in crawl spaces, blah, blah...just do it.

While the Elicent doesn't call for oil, it does call for a yearly inspection and cleaning. The easier it is to access the fan, the more likely it is to be serviced. Can't remember the name but, some poster here pointed out the oil hole built in to his fan by the manufacturer for no other reason than to apply oil to the motor.

Elicent runs 5-15 dba quieter than Vortex model for model. Just as your Elicent is quieter than a Vortex, so too is my 4" Elicent about 5-10db quieter than your 6". Quadruple silenced with muffler, insulated duct, fan isolation box and fan speed control on it's lowest setting, it's audible more than 80 feet away. The only person allowed in the garage during the inline debacle took less than 5 seconds to scrunch his nose and ask, "What the HELL is that NOISE!?!" Moving the fan outside the grow area is a great idea.

Warm moist air when it goes into a cold attic will condense water, at least mine does when it goes through a cold room. Which is why I use thin wall pvc sewer pipe for the air duct - its can be hung easily and the water will drain to the lowest point.....
 
I'm in the middle of converting a spare bathroom to a clone/mother/veg area myself. Took out the cheesy bathroom exhaust/light fan, cut the romex cable & wired up a junction box in the attic so i could just plug in the 275cfm 6" Vortex and use the bathroom wall switch to turn it on & off. I added an extra 2x4 to the roof truss for support of the fan, and installed a 6" round alum. dryer vent (with the deflector & flapper removed) on the ceiling to attach the flex duct to. Worked out great.
Air intake is from the cool basement thru a 4"x10" register grate on the floor after i unhooked it from the furnace.
No heat issues yet since i'm only running T12's & T5's but we'll see after i fire up the 400W cmh over the tub area. If I can't keep the temps down i'll get a darkroom vent from B&H Photo for the bathroom door or the 449cfm 6" Vortex & swap 'em out.
You can't hear anything at all with the door closed & only a slight, low decibel air-whooshing sound in the room itself. The Vortex is about 8' away from the bathroom ceiling opening blowing straight across the middle of large attic crawl space i have.
I'd be afraid of using a cheap inline in my attic since summer temps can go up to 120F + , and i like piece of mind with the build quality of the Vortex.
