stanley blower not keeping up wit temps?!

[dontstepongrass]

i have a cab built into a closet and am having a very difficult time with high temps. i am running a 48" teklight 8 bulb t5 in 12 sq. ft. i got the stanley cranked all the way up and i even disconnected my carbon scrubber. still, the temps creep past 90. the exhaust is being dumped into the room (hesitant to cut hole to attic) and the room temp is 63-70 (gets hotter after while because of exhaust.

if anyone has any suggestions...

i can think of exhausting into attic, replace fan, get a/c in room. maybe someone else has something else i can try first.

i dunno what to tell ya man, i had my stanley blowering cooling off a cab with 2 400's

My vents to the attic are in a small closet, so it won't require a picture perfect job when I repair it down the road.

Perhaps you can do something similar.

You could also look into increasing your airflow. It sounds like you're pulling air out of the cab, but the process would be much more efficient if you were pushing air into the cab at the same time.

Maybe a small inline fan pushing air into the cab would make the necessary difference.

Otherwise, prepare to cut into the ceiling, or add an AC in the room. The attic route is best imo, because you can avoid the extra power draw that an AC would introduce, and an AC would require you to vent out hot air anyways (I think, not sure.)

Good luck whatever you decide!

thanks for the input! the idea about adding a fan on the intake is interesting... any ideas on how powerful a fan? would another stanley blower work? i guess time to stop being a pussy and make holes in my new place. the exhaust into attic may stop the 8+ degree increase in ambient room temps during lights on.

 

[Mr. Bongjangles]

You would want the intake fan to be about the same speed as the exhaust fan, just a little bit slower so you maintain negative pressure in your cab.

Another Stanley blower would work, but with a carbon filter reducing the CFM on the exhaust end, it might push too much air to maintain negative pressure. Those have settings right? If they do, just run it one setting down or something.

a stanley fan won't keep your T5s cool?! sounds like something is very wrong there.

 

[stke_fingas]

LMAO are you kidding?

maybe you just need a few more intake vents cause my stanley is CHAMP. it honestly flows way more air than you should need to keep your temps in check. i have a stanley cooling a 400w in a 6 cubic foot cab. it's even sealed and CO2 injected. i don't see how you would have problems with keeping some floro's cool. i'd make a few new intake vents before i did anything else if i was you. i think the stanley is about the same(or close to) as my 6" canfan. i think 2x the intake is what your looking for. so two 6" vents(or equivalent) should be enough to let the stanley do it's thing. you should be running a few above ambient at most with proper intake.

I vote with Stke. Unless there's something bummed in the blower itself, it's got to be pilot error.

I can't say the Stanley is great but it should keep things rather cool. I use mine for intake and a valueline cap 6" inline for exhaust.

i would put the stanley in the attic pullin up the heat from the box. worked for me down here in the south very hot. now i have my blower stickin half way in the wall blowin in the wall.
with it venting in another room. carbon filter is hidden in the wall no wasted space

 

[dontstepongrass]

well i cut a hole into the attic and ran the exhaust hose up there. my running temps are now at 88. i will get another stanley to try on the intake and i'm also looking into a swamp cooler for the room.

 

[dontstepongrass]

also more powerful circulation fans to push hot air up past the light

 

[dontstepongrass]

since the stanley blower has two intakes, can i just block one intake cutting the fans output in half allowing me to maintain my negative cab pressure or would that fuck the fan's motor up somehow? at $40 i might try either way

anyone?

Nah don't do that..

If you have to reduce the efficiency, add curves & bends to your duct between the blower and the cab.

The Stanley blowers I see on the web all seem to have 3 speeds though, and are like 50 bucks.. Get one of those if possible so you can adjust the speed to whatever is appropriate.

 

[dontstepongrass]

got 1. just waiting for shit to heat up (hopefully not too much)

 

[dontstepongrass]

ok... shit is still just too hot. its at 90 no matter what i do. im thinking a/c is the only way. lower the temp of the incoming air 15 degrees and see what happens.

what do you have as far as intake?
My stanley likes at least 144sq inches of intake to run without significant backpressure on the fan. 180sq inches and it'll run smooth as butter.


Is your temp gauge facing (and very close to) the lights? That could result in a skewed reading.

What about the placement of your fan and filter? You have it towards the top of the closet right?
Even if its not, I had my can sitting on a can66 filter (so about 2 ft off the floor) and it was still sucking all the heat out of a 4x5x8'H space on low speed with 400w of lighting.

 

[dontstepongrass]

that's crazy. my intake isn't that big. not yet at least. i got maybe 50 sq inches. would u mind me asking how you got the 144 sq inches configured? a 12"x12" vent? or a couple intakes spread around?

have several temp gauges. got 3 in the cab at moment to take readings from ground 3 ft under light, a foot under light and also one getting the air above light.

 

[dontstepongrass]

filter i removed until heat is dealt with. fan is pulling air from 8" from top of 7 foot tall room.

when you try to dial in heat do you use circulation fans?

what are your ambient room temps? where does your intake air come from?

 

[dontstepongrass]

ok. i installed a window a/c in the room that the intake air is drawn from. this should keep my intake air at 60 degrees while lights on. i'm sure my ventilation still needs some work but if i crank the a/c i wonder how much closer it will bring me.
