These Fans Are The Real Deal !!

I meant Fan Speed control,
BBB, where do i get one DPDT,OR SPDT
who makes it

DPDT is double pole double throw. A switch that controls 2 lines (wires), and can divert it in 2 different paths (center off means it has 3 positions, and center position is off)

SPDT is single pole double throw. Same as above but with only one line controlled

Lowes/HD just might carry them.
 
for the people that have these' fans, are they as quiet as the advertising suggests?

for the 100 model(highest RPm) it says less then 25 DB which is like a computer fan...as for the 100x 125 150 4 5and 6 inch fans says there barly over 33 Db with less rpms then the first.. im not sure how fans all diffrent sizes moving diffrent air are rated the same i also thought bigger fan + lower rpms = less sound :p would just like alittle clarification from someone who has one or knows something about this subject because i know some of these inline fans sound like jets :(

I haven't measured the dB (might) but its not all that quiet (I used the slow speed) But I could have mounted it better too. But maybe I'm too picky.
 
I am looking at the 150 model. My guess is it's all relative when the other models sound like a 747 is landing in your closet.....
 
bigbud : which model do you have?

relaxed : well yea but i was looking at more of the fact sheet since i had no opinions..the 150 is rated at 33 db..which is reasonably loud but compared to other fans ex: vortex which is rated at almost 50 db for the same air flow... thats about
100 x diffrece between the fans asuming the information isnt compleat bs and assuming im interpreting it correctly :p

at the moment im deciding if i want to start growing again... and a quieter fan and a lower heat light will be primary concearns... considering the space i would be using would be fairly small and in a poor spot so im looking into these fans which have very good reviews from what ive seen.... and into led lights cuz they look cool :)

Yes, go look at switches, they will be marked, SPST, SPDT, DPST, DPDT.

Find one with a amperage rating above what the fan draws.

or just wire it up so one speed and be done with it.
 
Hey all,

Sorry to bring back a thread that's been stagnant for a week, but after reading it all I'd really appreciate some advice regarding these fans. I have a stealth grow cab that's 2.1sqft and roughly 10 cubed feet of volume (small i know). My question is which model would be best suited for my box? I'll be planning on passive intake since the back of the cab is only that thin cardboard material that i stapled on and a few drilled out holes on the bottom.

S&P fans:
4" TD100 - (135/100 cfm) or the 5" TD125 - (197/149 cfm)

I have a nearly 5in diameter cooltube for my 250w MH/HPS. I plan on mounting the fan on the inside of my cab and have it blow thru the cooltube and out the exhaust port since they're only rated at 104 degrees f. The cabinet will be exhausting into my 55sq.ft closet. Would the said suggested fan also be able to pull air thru a DIY carbon scrubber? I have never messed with any kind of ventilation scenario so this is all new to me.

Criticism is very welcome !!!

Thanks in advance

and fwiw, i only plan on having a max of two plants.

Keep that exhaust as high as possible in the cab, and keep the ducting as straight as possible..
Your plan isn't the best though.. A cooltube should have its own ventilation, and be isolated from plant air.. Exhausting past the bulb will increase odour volatility, and you should be pushing cooler air past it anyways for heat transfer..
Lastly, <200cfm will get reduced to pretty much nothing it you tack a decent filter on there..
 
So after reading this thread I believe that these are the fans to go with! So here's my set up. For the moment I'm going to have a 10x7x7 room, which I plan to have 1 600 watt on running but with another hood attached for when switch into flowering mode will have 2 600 watts going. Could I get the TD-200 and be fine running a Y line for exhausting the hood air out of the room, as well as the other line to take the hot air out of the top of the room? I'm going to have to put a carbon filter on the end to filter out the smell.
 
The 200 is very powerful and should handle the job well.

It is not stealthy but it is a bit quieter than an 8" Vortex.
 
Thought my thread might recieve better info. from the experts in this thread since the s and P fan is a major issue here...150 or maybe 200 maybe 100 & 150? I don't know but I see "that's not the best venting approach a lot and that's what I want....The best approach please help...I want to pull the trigger soon... and other then the 4 and 6 inch duct fans all needs purchasing....

Researching it appears I will have to have 3 ceiling holes for venting? The intake and exit for cool tube as well as one for the carbon filter. Soon the southern heat will come and pulling +100% heat might be an issue for thru the air cooled hps? At the bottom of closet entry air hole from a/c room as well. I was hoping for only to cut 2 holes in the room but my research is not showing it.
What do you guys do for this issue?
Can someone comment please before I start cutting holes in the walls. Here is what I want to go with....

- size room total veg/flower- 8 x 8 x 2 closet

- 400 watt air cooled flower/HO t5 cfl veg.

- S and P TD150 inline fan low noise for carbon filter can 33.
- duct fans 4" for room air entering flower and veg area using a y piece.
- duct fan 6" for air cooling the hps.
- to be determined fan for veg. part of room exit.

I am a do it first time right guy pondering this for a while so comments appeciated.

Was hoping to keep low noise and few room holes as a goal? Thanks
 
i don't have time to read through 50 pages so could someone recommend a good carbon filter to use with the td-150 6" fan? Should I just go to the local shop and pick up a can 33?
 
yeah these fans work good, but if your goting to put ducting and filters on them, go to the next bigger fan, the 100x fan is worthless, i now have a 6'' exhaust and a 6'' intake, and my room is 6.4 x 7.4 finished diamentions
 
Hey guys,
First off, great thread. I have found it to be very informative.

That said, I have a question for the group:

I have a 48x48x24 inch cabinet. I have a 400w HPS in there in a cooled hood. I currently have two separate noisy-ass axial fans. Computer-style.

By other peoples' system of figuring these things... it would seem that i only need 11cfm or so. I am thinking that i need more because of the HPS being in such a small space.

I was thinking about going with the S&P TD-100 4" fan, and then using a splitter and having that fan both cool the light and the carbon scrubber.

Any thoughts on this matter?


THX,
BILLDO
