Silent fan = low CFM

Moving air is noisy. If it's really an issue then build a muffler for it. If it is STILL an issue, cover the fan in fat matt anti vibration matting.

^This.
For me, i have a 10" fan that runs about quarter speed and the fan is silent. Only noise is the air moving through the ducting. Could switch to insulated ducting, or a muffler.

That's what I'm talking about. I'd buy 6 inch with 600 m3 and use a speed control.I think it's the best choice.

the lowest DB in a 6 inch inline fan (400 cfm) is active air

the new video out i found is this

get a box fan they are so much better then the "turbo" type fans they pull just as strong but are way quieter

You could easy get a 600cmh or even a 1500cmh, a lot of the noise is caused by the size of the ducting as its the noise of the air traveling down the pipe fatter pipe means less noise but most box fans are a lot quieter and produce less vibrations then the turbo style fans.

Thanks for information,but how to set up a carbon filter with cool tube in the box ? plus extractor fan..It's impossible in my box 1m2.

hang the carbon filter u have that matches to the speed of the fan......at the very top of the area then hook the ducting to the other side of the cool tube


carbon filter.....ducting......cool tube......ducting ........fan.........ducting ....ejection point

But in one line - carbon filter + extractor fan would be more silent than your method,justugh,don't you think ?

the method i told u is the common one
u get the smell controlled plus the heat in the tent and the cool tube is cooled all off one fan on one line

sound is not my issue heat from the equipment keeping the area cool and under the FLAIR radar ..................as far as noise to me it sounds like a 12 inch fan going on medium or high ...........and if i want that less i can always make a muffler box to slide over the fan itself ( just have to monitor the temps if gets over 130 the fan will kill it self for safety)


u do not want to hang a fan in a tent.........think about it the heat from the light is collected and passes back into the tented area .....the noise lvl is higher do to it being inside a reflective surface close together (think tub and waves in water) ........the fan alone is near 20 lbs most tents areas can only do 50 to 70 of gear inside (only gorilla can do 300 lbs)....plus u have vibration from the fan that can make the crossbars slide out of place

Thanks for information, Okey, I'll make that method so the extractor fan should be outside ? by the way the carbon filter has to be ducting to cooltube from which side? from socket cooltube's?

the point of the cooltube is to pass air over the light to remove as much heat from it as it can

the carbon filter is the start point this cleans the air before u get rid of it the cooling the light and removing the heat is a secondary action

the side u want it on is up to u personally i leave it on the side that is open (u can put hand down the tube and remove/add bulbs side) that way u can just unclamp it and the air is still being sucked in turn the light off wait 5 mins and u can change it out reclamp the ducting back on from carbon filter and u are done
