Need a quiet fan

[Bobb11]

Hi all the inline fan I have for the tent is a grow lush one and I can hear it at the other end of the street. Can someone advise me on a good quiet fan

Cheers

Depends on your price range really. I have heard good things about the Fantech Silent range, and while looking at their site I see they now also have a Whisper Jet series which is quieter again. The difference is the Whipser Jet also comes with attenuators. I'd bet both types are pretty expensive.

Couple fan with acoustic ducting

Filter fan acoustic ducting

I have a 200mm in line

Solely to exhaust heat from clones under fluo

I have a fan speed controller on that and I can hear the inline over everything else

All the best

Thank you for the quick response

If money is an issue for ya , I made a great silencer box out of an old esky. Cuts noise by 50% and still pulls full power.

I cut 2 holes in either end for ducting and the fan is easily accessible through the lid. Could be an option till a top shelf fan can be obtained.

Cool idea

Keep your fan man, you can kill the noise.

 

Like Conetar I also built a silencer but used MDF, Dynamat & glasswool insulation + insul. ducting. Then built a muffler at the outlet using a 20 litre bucket, chook wire for the 'tunnel' and glasswool to fill the void between bucket & tunnel. My growlush mixed flow is now inaudible. IME acoustically optimised fans are good but nowhere near as quiet as a silenced regular model.

 

FWIW rockwool is the best broadband acoustic absorber money can buy. If you look for premium industrial/commercial acoustic insulation it's rockwool. Got any spare?

Can confirm, I have my fan sitting in a box with rockwool surrounding it, really helps with noise.

Yup, I did the same. Put an in-line fan in a cardboard box and filled the space in the box with broken pieces of Styrofoam and it's made a good difference.  So much so that I'll be pulling it apart and re building it with better material inside because I know it works.
