Did I buy the right extraction setup?

Hola Rollit vets,
Yet another newb at which to take a shot; Secret Jardin Pro DR120 II (4'x4'x6.5') in empty garage appx. 18'x8'x10' - yes, I will be venting externally from tent through garage wall to outside (passive intake so far). I just purchased the following:

http://www.4hydro.com/growroom/can-fan-combo.asp

It just showed up on an industrial pallet (I know I'n new, but this thing's huge!). I'm concerned that I will have to pull air through my 400w HPS cooltube and then push (outside tent) through filter; aren't you always supposed to pull?

Any vets with advice; much appreciated!

CAN 50 Combo (6-inch HO CAN fan, filter, flange): 300+ cfm w/ matched filter attached

It says from their site:
You can either blow into the filter, or draw through it, it'll work either way, but it's best to draw through the filter, using the included pre-filter to remove dust before it gets to the carbon inside (dust pockets forming in the carbon over time will limit the filter life- which is also a good reason to clean or replace your pre-filter regularly). You can use bungee cords to hang the fan from the ceiling or rafters to absorb vibration from the fan. This will lessen any potential fan noise in your home. You can exhaust the filtered air either back into the same room (which is referred top as "polishing" the air), or into another area utilizing the fan/filter combo as a pre-exhaust air cleaner. The length of ducting you use inline or on the exhaust end will cut down on your air flow if you use too long of a length. Long stretches of ducting may create a need for an in-line booster fan especially on the CAN 2600 or 9000 combo's.

It looks like this isn't setup to hook up to a cooltube...to pull through the filter it just directly attaches to it with the included flange, then out to ducting. I've seen other filters that come in a canister with intake and exhaust hookups, but this doesn't have that external shell, just the wrap that air flows through.

Just looking at the pictures and reading the description on it, this isn't going to work how you want it to, but it will filter the shit out of your air :D

You could be creative and build a shroud that surrounds the exterior of the filter with some sheet metal with some space for airflow, and attach an "exhaust" port on it.

Here is a diagram of what I mean of how the can looks:

What you could do at this point would be mount it all in order of filter->fan->cooltube->outside, it's not ideal, but it should work considering you only have a 400watt HPS :)

when u connect a fan tru ducting to a cool tube its better to blow the air tru the tube instead of suckin the hot air tru your fan because it will run down and eventually burn out the motor in the fan.

I thought cool tubes worked like air cooled reflectors which need air sucked thru them as centrifugal fans are designed to suck, not blow, the best. Heck Ive been reading & working on my room for a while trying to get the combo right the first time. Hold out for & listen closely to those with REAL knowledge & research what the rest of us say . ..

Massah, thank you for your in-depth thought; I was indeed concerned about the look of the filter itself, considering as your image showed, there seemed no indication of input/output flanges on both ends. I will consider your homemade approach, and in the meantime, I guess I need not worry about smell :-)

it will not do that i always PULL through the fan and its suggested that you do that too.....I bought some of my fans used and ive been using it for yours all my fans get pulled through not pushed and the life of the fan seems to not be affected one bit

Just connect ducting to the OPEN end of your cooltube then connect the ducting to of OPEN end of your filter ........ Air will be pulled into your Filter from its outside surface then be pulled through the filter into the duct then into your aircooled hood past your light then into your fan and then exhausted to where ever you exhaust your old air( hopefuly outside) this is the normal way of doing it this is how the filter was disgned to work.......

so if should go like this Filter>duct>cooltube>duct>fan>outside.......make sense??
