347 CFM S Line S-600 Fan, 6"

WOW. This is one EXCEPTIONAL inline fan. does it cost more than the competition, a tad yes, but with a ten year warranty no other company can TOUCH this. Also, though this has no effect on it functionally, it is a beautiful fan. This will allow me the giant sized "computer rig" setup im looking for visually in my grow facility. I purchased two and both were exactly as advertised.PROS:Build quality is outstandingAttention to detail in function and form (something as little as a rubber grommet around the duct joint may not seem big, but it is HUGE for stability and vibration)Small fan, BIG airImpossibly quiet! a db meter may tell you otherwise but in real world usage, with insulated ducting, this thing is whisper quiet.warranty is nearly 10 times as long as most of the competition.CONS:Cord Location. Really that's it, and it isn't a big deal, but with the fan setup like its pictured on its product page, the cord comes straight out of the top. the dampener is to be put vertically centered...doing this is simple to rotate the mount, but makes the cord come out the top instead of the bottom..no biggie but makes it a tad hard to hide the cord in exposed setups (which shouldnt matter if you arent an anal grandmaster grower)CONCLUSION:If you are wondering whether this fan is the one for you, all i can say is.."is it an s series atmosphere fan? then HELL YES". I am what most would consider an expert when it comes to growing and the new technology that's come in the last few short years has made growing not only fun, but "techie"..now i can nerd out with computer controlled LEDS, WIFI temperature sensing with ip look up, temperature and humidity control i could only DREAM of 5-ten years ago all accessible from my phone or tablet or laptop or desktop. Long story short,,, the ladies are spoiled and beyond happy, in part because of these beautiful fans..dont hesitate to purchase these.p.s. the seller was fantastic and FAST. :) ill update the functionality of these bad boys in 6 months.

Still a bit noisy but was easy to install and appears to be very sturdy in materials and design. It was much easier installing into a tent with one person than Can Fans or MaxFans because of the mounting bracket design.Only had it for one day but looks like it will hold up well and do exactly what I needed it for. Really happy with the 10 year warranty offered with it.The price was right in line with other fans of similar designs like max fans but with more features. This fan has a built in damper and is insulated to control the noise. Much quieter than Max Fans.I will write an update if anything changes but I doubt it will. I’ve had one of their cheaper metal case fans for more than 10 years and I have had zero issues with it.

Great inline fan for my small personal grow tent. I bought the fan in April of 2014, and it has been in continuous service since then without a hiccup. Friends told me the fan would last four years but it squeezed out a few more. The speed control was a blessing as I often daisy-chained my veg tent to my bloom tent and needed a bit more pull to clear both. It did get a bit louder over the years- volume on par with a dehumidifier running. No complaints from anyone in the building, though. I replaced the 6" Vortex S-600 with the same model just a month ago. Why not? Dependable, quiet-ish, and a workhorse- just as promised.

I've used fans from AC Infinity and Fantech with the same CFM rating and they are much quieter than this fan. It isn't even close. I don't have a decibel meter and I understand that noise levels are logarithmic, but this fan seems ten times louder than the AC Infinity and Fantech fans that I am still currently using.

Great little fan, a little concerned about the Static Pressure drop off being a issue longer term. But when compared against some of the other brands this fan has it all. Quiet, sleek, lightweight and adjustable with the proper fan speed tool. I tried a few AC/DC and Dial-A-Temp (recommended from the MFG) and they both worked but created a buzzing in the motor. The AC/DC specifically was obtrusively loud when run anything under 60%. In the end I ponyd up for a Variac variable voltage and no buzzing can be heard while allowing for sub 60% running speeds in my 3x3 space.

I’ll start by saying this seems like a great fan. Build quality is great, quiet, and the included bracket makes it super easy to install and take the fan off without having to remove any of the ductwork.For my application (homebrewing) this fan didn’t work out. Had issues with condensation build up and dripping from multiple areas of the fan housing. Not surprised to have condensation but due to the housing I wasn’t able to seal and drain off the condensation from one specific area. Going to go with the VTX600 vortex fan as others have been successful in draining off the condensation.

I’ve had it for multiple years and it still runs perfectly. The auto shut off feature has been wonderful as well since I’ve had some cloth string get in there and it turned itself off to prevent a fire.

Excellent fan! It is lightweight and powerful. The sound is acceptable for grow tents, and it is much quieter than my other in-line fan. Nice backdraft damper to keep outside air from blowing back into the tent when the fan is off. A bit more costly than some other in-line fans, but nice high-end product plus 10-year warranty.
