Ho-lee-shit. Whisperline is HUGE compared to a Max-Fan...

Okay. I bought a whisperline when I started because I heard it was the quietest. Well, it's not that quiet. It's reasonable, but no where near the kind of quiet I want still, so I built a muffler and managed to quiet it down decently.

However, the thing is freaking huge. I thought it seemed big when I got it... and now that I am replacing it, I see how huge it really is.

I bought a Max-Fan 6" Can Fan to replace it. The thing is like 6"x6". It's absurd how small it is compared to that fucking whisperline monster I have floating in my tent precariously. It also weighs like 1/5th.

I know this is probably really obvious to some, but this is a learning experience for me and I wanted to throw this out there as a warning to anyone considering getting a Whisperline just because they're said to be so quiet... if space is a concern for you, you might want to keep shopping. When you factor in the space needed to attach an immediately-bending duct to each end, the thing needs something like 2.5-3' just for the blower... then you've got a carbon filter? How the hell does anyone with a tent make that work? And why would anyone with a room setup bother with such a low cfm fan? heh.

Edit: That being said, I just plugged the max-fan in and I think it probably is louder... will see how it sounds with good insulated ducting, though, i HOPE it will work out to be pretty quiet when capped off... if not, I guess I know that's why the whisperline is so big.

Is there something about the cage-fan design the whisperline uses that makes it so quiet? Is it inevitable that we have to sacrifice space for a quiet fan one way or another? Because none of these things are even close to quiet by my standards, and since so many growers are stealth, I would think the same would apply to their standards.

At least this max fan I can wrap in a blanket real easily after I put the insulated ducting on...

Hahaha... the extra space may well be worth it... should have gotten the 8" whisperline...

These are the greatest fans, extremly quiet, half the noise (20db) compared to a panasonic whisperline (40db)

I have experience with both fans. The whisperline is actually stronger than the TD series. I also knew about the size when I purchased the fans because I READ the specs before I buy. Something you should consider doing before you purchase. The whispers are extremely heavy and bulky but I would use them over can fans any day. If noise wasn't an issue I'd then go with the stronger fans.

The TD Silent series may be slightly better than the whisperline now because of their new design. Very light and small but they also have created an enclosure that basically fits around the fan somewhat like the whisperline which makes it a bit larger than the older style.

The TD Silent can only pull a very short run. You need to look at the "wg" charts and see how they compare. The more silent the fan the less pull they have over long distances. I posted a series of reports a long time ago about this stuff. Hope you find what you are looking for.

edit: Holy crap have you seen the weight on those new Silent series fans? 20 and 25 kilos for the big ones!!

If my fan and filter were too huge to be inside the tent I'd do something off the wall and crazy like having it outside the tent. Tents aren't stealth so there's no reason to hide it eh?
