Quietest and lower cwattage consumption exhaust fan?

**GANG GREEN** · 31-01-21, 11:11 AM

Setting up a new room and triying to figure out if go with other than the rvk 250 for something like the ac infinity T8 for example. Got the rvk inside my own silencer as the box it wasnt enough, also the whole room is copopren covered. (Silencer; wrapped in copopren 2cm, pvc 0.5ml, more copopren till rubber 100l garbage autosealed can in and out carbon filters)

wondering what you using and what you recommend. Thank you in advance

My Ac Infinity S6 runs on the 1st setting and is almost silent, as its an EC fan it pulls 4w at the wall in doing so

The cloudline range are very impressive, If you go for one make sure it has the updated controller. The old ones switch the fans off when it hits the desired low temp/humidity or below (obviously really bad if you are running a filter). The new controller allows you to set a minimum fan speed so its constantly on at a low speed setting to keep the filter working properly.

I bought the S6 version a while back because of the controller issue and the new controller separate when they released it. The controller is £50 standalone.

Thank you Mac. i guess for a 2 fluence room will got enough with a T6? . I will keep in mind about the controller. The noise is my main concern.

I cant hear mine over the top of my other fans unless it ramps up to max and even then the max is only 32 decibels

to work out which fan you need, measure your room in feet

Length width height. then multiply them together. So for example if your room is 10 foot by 10 foot by 10 foot, 10x10x10= 1000 cubic feet

All the fans list how much air they can move in cubic feet, so buy the fan accordingly, you generally want to add an extra 50% on to cover your filters and ducting which sap the strength of the airflow. So for a 10x10x10 you would want a 1500cfm fan.

a 1500cfm fan running at 100% would be noisier than a 3000cfm fan running at 50%.
