Ey guys I was wondering is a 80watt 6400k e40 cfl for 17 dollars worth it?!
So I bought the wrong cfm fan ; I got a venTech 190 cfm with filter both 4" for $100 on Amazon . They have one same brand 6" 440 cfm combo for 140 . Not sure if I should get this or anybody got any better ideas? I have till the 31st to exchange but I used it so I don't know Amazon's policy. Also I thought the fan was loud.
well, what are you using the fan for? I use a ventech 440 and it's a great fan.
I think your CFM is your control is 190 enough vs 440 you had.. perhaps the "loud" Fan if your stealth.
I don't understand a word you said. If you want to try again
not sure what your fan is being used for .. but the CFM 190 vs CFM 440 ..250 cfm difference == your going to get less air or remove less air with you 190 compared to your 440..... as a scrubber as out against in you could make it work. an adapter will help from 4/6 again depends on what your using it for.. Just for grins CFM stands for Cubic Feet per Minute measure air intake and exhaust Velocity.
Mine goes Canon filter to light out to fan out to room in winter out window in summer. So far it puts my temps at 86 f for mh 600w and 84 f for hps 400w or 90s with 600w hps and doesn't clear the 3*3 of smoke (no smell yet) very well. It's probably the cfm being low but I was wondering about the brand because of the noise.. is there a quiet model? Is 6" quiter then 4"?
Can-filter (insulated) - Vortex S I'm sure there are others you can box and pad them also. As for 4 vs 6 a lot is what your pushing or pulling( length of run ) straining or maxing a fan will wear and cause noise in my experience.
It's loud with or without a load. Vortex s has 347 cfm in 6" or 728 in 8 " maybe the 6" will work for me . Is it much quieter or just slightly?
6 is fine .... with ventilation bigger is less wear if you have room you can always use a variable extension to get your control spot on. noise is a little more with the 8 not sure how stealth you need to be but you would not need use 100% on your speed control either... if your at that temp with 440 already not sure if you use co2 or not but your temp is right at hot so 8 is a better move in my opinion but 6 will work.. so the original CFM-190 is going back because your temps would be way to hot you have to have a bare Min of 440. 90 degrees without co2 is way hot.. 75 - 82 max in my opinion... so if you use less than 440 CFM your temps will RISE so no vortex 6-s will work if it puts out 347 and you need 440 .. you must have a fan that produces a slight bit more than 440 cfm in my opinion. ==== 440 CFM temps in 90s to high so you need more air option of booster or go to a higher CFM fan either way more air or cooler air lol
So it's btwn the 6 inch vortex s + separate filter + controller $230 and olnly 350 cfm.
Or venTech 6 inch combo b for about $130 with 440 cfm.
440-CFM VenTech would be your only choice in my opinion between the two...
You're missing an alternative fan that is rarely mentioned and is rarely offered on any of the typical equipment sites. Check into
Soler & Palau (or S&P). Their TD-150S is about 50% quieter than the Vortex 6" and much, much quieter than the VenTech. The Vortex 6 is running at about 75 dB as compared to the S&P TD-150S which is running at about 53dB. The TD-150S does cost about $30 US more than the Vortex. (333cfm and $184 - no controller)
