I have 3x5x7 tent with 4" 172 CFM and 4" CF running through about 12 feet of duct, CF, cooltube, silencer... and about 540* worth of bends. I don't know how fast the air exchange is, but it works fuckin tits. The sides of my tent are sucked in slightly from negative pressure and there is no odor outside the tent in full bloom.The extractor (fan) is way to weak for your tent. You're want to make sure that the entire air in the tent is filtered around 2-3 times a minute. ex. my tent is 1mx1mx2m. Therefore my extractor can filter around 280M³/hour AKA 4.6M³/minute and it only costed me $60.
Square feet is not volume.....its area...... Which would be fine...if you were trying to figure out floor space?It's a tent, it's going to have leaks. The key is to make sure it has negative pressure.
Randall, the 4" fan may not be strong enough for the filter. Figure your volume (112 sf), you should be blowing that volume of air out a few times every minute, meaning a CFM rating of about 400, AFTER you have taken into account the drop from the filter and any bends in the hose. How big is your intake?
What is the power rating of your unit, if you don't mind me asking?I just have an ozone generator in my room with no carbon filter or exhaust from the room and I have to burry my nose in the plants to smell anything..
