So I have a pretty small grow cab, 2x3x4. Im going to have 3 plants in there with a 400w HPS. Will this fan properly vent the odor and heat through a carbon filter? Its 144 CFM

I guess it depends on the carbon filter but that fan dosent put out that much air and if there is alot of restriction on the filter then that fan probably wont cut it

google how to calculate CFM and do the math. Not being an asshole just so you know for future reference. It would probably be fine using that fan though to answer your question.

Well that doesnt really apply, atleast I think, in my situation because of the carbon filter. I know the formula, but when you throw in the carbon filter, your going to need more CFM's then you would normally without a filter.

Yes and no...I would rethink using a 400 watt bulb in such a small room or either buying a balast that will support more than 1 wattage bulb so you can use a 250 or something in the small room and one day use the 400 in a larger room. Heat is going to be a mother fucker to keep down in that small room especially with such a large lamp.

Erikm, I know I suggested a couple types of fans for you already but here goes anyway....
Get a squirrel cage fan or an inline centrifugal fan. That said, the blower you linked too may well be a squirrel cage type fan but think about how you plan to use it. It will most likely need to be attached to some ducting which is going to be very difficult with that fan. If you still insist on using a cheap fan, at least consider the Stanley blower from walmart which you know will work acceptably.
The reason we suggest the expensive fans is because of a thing called static pressure. When you blow through a carbon filter, the air has to be "pushed" through the carbon in order for it to work. If you use something like a bathroom fan or a box fan, the air cannot get through the carbon and instead the blades just spin uselessly and no air is moved at all. Static pressure is the amount of "push" (pressure) that has to be generated inside the duct before it is able to move air through the carbon. So, you need to find a fan with some balls.... The only types of common fans fit the bill are squirrel cage and inline centrifugal fans.
