These Fans Are The Real Deal !!

good to hear man

And it would release all its smoke. Its not rated for the loads an AC would toss on it. Its *just* a fan controler.

Man I'll never stop loving that.. Its even better than 'If it ain't broke, fix it till it is..'
You could use that to flip a relay driving the AC, if you can get one big enough.. If its 120V it should be easy enough to salvage most of whats needed from a broken space heater or whatever.. Then again, if you're willing to whip out the soldering iron you really wouldn't need that fan controller anyway.. Thermistor circuits are pretty simple, and all over the net..

Ah, yes. The magic smoke. Once the magic smoke escapes, it will never work again. Just basic science!

I have search all over the net high and low, but still can't find those "smoke re installation kits"

 

[Skunk Baxter]

I think that's because - being magic smoke and all - it only works in whatever appliance it originally came in. I figure that must be the way the spell works. If you try to put different smoke into a device that's lost its magic smoke, the new smoke will not have the proper magic. It's the only explanation that makes sense to me!

 

[born2killspam]

Are you living in the dark ages?? The smoke is more like fuel.. The device is kind of like a gas/propane tank.. If the smoke gets heated it expands.. If it expands to a critical point, the device ruptures, and can never contain smoke to power itself again..
Stone me for heresy if you must, but that is the scientific fact of it..
Magic smoke.. What an idiot..

I plan to purchase the TD150. I'll be growing in a mills cab 20x30x70 with a 250 hps planning to use the same fan for a future 400w cool tube upgrade.
1. How many of the 8x8 inch light tight louvers will i need to allow good passive intake and keep negative pressure? When i do the math i only need one, but i don't know the physics when it comes to intake air flow restrictions. After viewing some of the layouts the fan will be outside the box pushing into a filter.
2. Does anyone use a variac instead of a speed controller? i've read that some speed controllers make the motor hum. I don't necessarily need a variac if there is a speed controller which won't burn or damage the motor.

Well, unless the motor was designed for variable speed, any controler will stress a motor. The standard for variable speed (not a 2 or 3 speed motor) is a variable frequency drive, aka:VFD. they screw with the freq of the AC sine wave to change the speed. and typically, if not all output 3 phase to the motor. (I have motor and drive here. The drive takes single 120 and makes the 3 phase to drive the motor) This is for AC motors. DC motors are a LOT easier to control speed.

I'll second BBB where he warns about speed controlling electric motors! Its dangerous and its 'louder' to run common electric motors at voltages other than what they're built for.. The only decent way to do it is with a pulse width modulator.. This gives the fan the voltage it wants, but not full time.. Its the equivalent of turning it on/off really quickly on whatever duty-cyle you choose..

Even a PWM with zerocross switching on a standard AC fan motor (inductive loads) is wrong. Its fine for resistive loads.

Okay, that was a lot of techy stuff letting me know to hook up the slower speed. Thanks guys!

using a TD series fan, 2 questions.

do you use them to push or pull?

carbon filter before the reflector (inside the cab) or after the fan, outside the cab?

my friend has the 150 hooked up outside his cab but hidden,he pulls the air thru his cab(flower) and pushes it thru a homeade scrubber,he leaves it on the high setting,no controller,293 cfm..was kinda loud,so the scrubber acts as a silencer as well,he bought more cfm then he needed,lost some on the scrubber,so it worked out well for him,go bigger,then quiet it,rather have too much cfm and insulate it or push it to quiet it

 

[Relaxed]

Check me off on this set up before purchasing materials please. This thread is worth money folks! I have read every page! You’re all bad ass! I am learning so much!
Concerned with set up location of can filter, fan (pull or push) and pulling open air from room thru open side of light exhaust. Was considering 2 Ys for light, flower and veg area but have yet to see anyone do that? I am going to use insulated duct material so I am planning on not using insulated clasps (overkill?) to save money with the insulated duct may not be a need for sound proofing the clasp?
I am in the south so heat will be an issue in summer of the attic
closet size 8 x 8 X 3’ (split in half for flower /veg. Via tarp)
Set up air pulled out of room?

Can-filter 33​

Ceiling 6” hole to Attic================​

TD 150 fan soler & Palau​

6 inch Y​

Duct 6” Duct 6”
Air cooled hps 400w (open end for flower room air pull extract) veg. Area


Bottom of room corner for house a/c air entering room
4 inch hole from house for cool a/c air entering room via wall hole

4 inch duct​

4 or 6” inline duct booster fan (own these already)​

Y 4 or 6”​

One end for flower area One end to veg. Area​

​

Suggestions please? Need to order in a few days……..​

I think i might use this! thanks.. help first???


The 6" TD-150.... 218-293cfm
since its so quiet, and powerful.. I am thinking I can use it to filter the box aswell as cool the bulb in my cooltube. What do you think if I mount this fan to the top of the 4'x4'x2.5' (33cubic ft) box in my closet, connected by ductiing to the 400w hps cooltube that will run horizontally along the top inside of the box?

as for intake.. would it be cool if I put two small fans on the bottom of the box, drawing cooler air in at a slower speed, creating a vacuum effect. sounds right to me.. what about you guys?

 

[BigBudBalls]

Keep in mind, if you split the ducting, the flow will go with the path of least resistance. So a little dampening might be needed. Just food for thought.

My overall feelings is toss the big fan on cooling the light. If using a scrubber/filter then that needs a big fan too.

I've read that pulling air from the room through the light into a scrubber/filter isn't the hot set up. Not sue why, but a temp logger can prove/disprove that.

the ducting wont be split..

here is what I mean..

Sending hot grow-box air out the filter is going to reduce its effectiveness.. When stinky things heat up they stink more right??IMO a cool-tube requires a dedicated fan, and should be fully isolated from the plants.. And if you can figure a way to eliminate that 90° corner where the duct turns toward the ceiling, you'll increase air-flow quite a bit..

 

[KillHit]

lol it will be rounded.. i couldnt figure out how to do it on the drawing.

if these fans are that good i believe it should be sufficient. 293 cfm ventilating that size space is more than enough, even when attatched to a cool tube. ive seen plenty of cool these tubes with far less.

 

[KillHit]

ohh, i see what your saying.
