New Fan By Can-Fan

Sorry, the 12" elicent at ~1,100 CFM was surprisingly quiet considering the amount of air it moves. But there's still a healthy woosh. The silencers on both ends was the really quiet option when compared to the Qmax fan. I felt like there was less "low-end hum" out of the Qmax though and when paired with silencers it was definitely super quiet also.

With that size fan you're just not going to eliminate all the noise. The difference between these two is minimal when both are properly silenced and the ducting is insulated. Too close to call.

Hi Snow Crash - would you go DIY silencer or commercial off the shelf.

I've researched DIY silencers a bit and seems like you just need an increased diameter and a length of 3x the circumference of the fan

So 12" inline fan turns into a silencer of 3x 12 or 36". I would like to research more but I bet the true number is pie or 3.14 so a DIY for a 12" fan would be around 37.68" long.

not sure how much its worth the trouble to be honest... other than maybe save a few bucks. after sourcing the correct accoustic foam not sure its worth the effort to be honest. I could pull it off fur surrr

I buy commercially over DIY. I find that by the time I acquire all the tools, parts, make 3-4 trips back to home depot for the little things that pop up... I spend almost as much doing it myself and to be honest, my time has value too.

The Phresh silencers work best in my opinion. The combination of a phresh filter, insulated ducting, and silencers on either end of a fan is a super-quiet system. It's a little more expensive to set up than the discount-value-cheap-on-ebay-chinese-shit-brands... But when it comes to the security afforded that's the brand I want and those are prices I am willing to pay.

I see people in places like Texas getting bargain brand filters, or trying to DIY them, and it's like... You people electrocute guys! Is it really worth the $100 in savings to chince out when the value of the finished product is so damn high. It's not like the silencers go bad...

The phat duct mufflers suppose to be better. They are built with fiberglass or something on the inside. Should last longer than the foam that most others use.

I'm not familiar with them beyond the experiences I've had with Phat. It's not a brand I would use myself but everyone is entitled to their own. I think it's interesting they are advertising 85% noise reduction in both the mini and the standard versions. No way the 6x13 is more quiet than the 6x26... that puts their advertising spin and hype on their product way into question. Based on other wild claims that have come from Phat... I dunno. Phresh's work.
