quietest extractor fan

evening kind people :thumsup:

looking at upgrading my extractor fan to the quietest possible .

Current fan is a 6" RVK in a mdf box with insulation round it, however its still too loud for my liking

i plan on buying a new fan after your recommendations and upgrading the ducting to phonic trap ducting.

i use an ecotechnics evolution to control environment so needs to be able to dial it down .

i have seen so far TD series and Vortex s line , anything else i should be looking at ?

Any help greatly appreciated  :yep:

Systemair silenced revolution, dunno how it compares but it is pretty quiet.

 

My runs at 18% silently, up to 65% pretty quiet and in the high ranges you can hear it outside the room with the door closed, but not much - practically any other house noise (central heating, TV etc) masks it.

It should be noted that Vector fans need to be used in conjunction with a G.A.S. fan speed controller, which was designed and engineered specifically for use with EC motors. The results are tuly mindlowing: you can regulate fans with pinpoint acuracy, right down to 1% of their output in 1% increments

 

as i already have a ecotechnics controller i don't think this would work tbh, I'm not sure though

Ac infinity was my choice there are some other they are just not a reputable as ac infinity. They do modular fans and mixed-flow fans the modular ones are slightly more expensive because they modulate depending on the temp making a sound like a PS4 playing fallout... The fixed speed ones have eight speeds at the bottom 2-3 speeds you can’t hear anything from outside the tent not a whisper. I’m currently running a 6”.

 

You can can get pretty decent inline fans out there but I do reccomened AC INFINTIY the mixed flows run for under £100 and they are very energy effecient too. It’s also worth investing In acoustic ducting like the airos or phonic trap.

 

What will cause you the most noise is your oscilating fan. You would likewise need to spend alot ££ to get a quiet ocilating fan and if your spending a lot on something to ocilate air then it should be an air cooler with hepa filter imo 

 

Combine the above with a silent light and you can sleep sound beside your grow every night.

Do you know where it's possible to order one in the UK, the lowest I've seen is around 150£ importing from the USA

Agree with the oscillating fan causing the most noise.

 

Have you got any suggestions on one that is quiet? Also you say one that will cool air as well? Got a model in mind?

There is a lot of new air purifiers on the market I would make sure you get an ozone free one. Other things to take into consideration would be led lights on the product effecting your plants night cycle or how the product switches on and off if it has a thermostat or if it can be attached to one. It’s probably worth investing in a good air cooler that meets your needs rather than good ocilating fan which Job is to cool the room primarily. Place it beside your instake perhaps I know a lot use hepa filters on their intake.

This is the one I got. There is a 4” model the same price but it’s modular. You can get a 4” fixed speed cheaper than that. However if you look on their site the 4” starting model is under production and will be re-stocked in March.

Google “air cooler with true hepa filter” you’ll find brands like Leviot, pro breeze for a cheapy. I go with dimplex because I need something that can be turned on from the plug. 

 

As for oscillating fan’s computer fans are always a safe bet they don’t oscillate but you could daisy chain a couple around your tent and hook them to a thermostat. Ac infinity do some super quiet cooling fans with speed controller.
