iPower to AC Infinity

I have a old iPower 6" exhaust fan and filter in my Gorilla 3’ x 3’ x 7’ 11" tent. I’ve had it four years or better and it’s always been a POS. Noisy China junk. At different rpm points it will bang around and sounds like its going to explode. Not to mention it’s huge and heavy and takes up a ton of space in the top of my tent. I thought now is the time to upgrade the exhaust system while I’m upgrading my HLG lighting. The only thing I skimped on when building this setup was the exhaust. I knew it would bite me in the long run. So now it’s time to pay the piper. So I ordered a 6" T6 and carbon filter. Not the unit with the Bluetooth controller. I’m going to pull the iPower unit out and setup the new AC Infinity blowing into the carbon filter and set it on top of the tent with just a short bit of 6" flex duct needed. This will free up a ton of space in the top of my tent making the long legged sativas a joy to grow now. The instructions said to use the prefilter sleeve as a liner inside the filter for the config I’m using. Looking at that it becomes apparent that is BS. That will never work right. So I asked the wife if she would sew one end closed on the prefilter thus turning it into a bag filter. Looks like that is going to work great! Slip the bag filter into the carbon filter, put the fan unit in and it all fits together very nicely. Two self tapping screws and near perfection with no bypass for the prefilter and no leaks at the joint.

@Blastfact the bag is meant to be on the outside of the carbon filter and replaced as needed to help save the life of the filter…not sure the way you have it configured will please you

Have you tried the prefilter sleeve to cover the outside of your carbon filter? That would protect your carbon filter from picking up airborn contaminates before introduction to your carbon filter.

It can go on the outside or inside depending on application. Blowing into the filter is actually more efficient when it comes to a pump. A fan/blower is a pump. It allows the blower to load better and keeps the blower on it’s curve better and establish it’s head pressure with much less restriction on the suction side which kills performance. When working with pumps/blowers we call this inducing head to tune the blower/pump. It’s a shame they don’t publish a fan curve or send one with the unit when you buy it. One never regulates flow of a pump on the suction side be it a open or closed loop. Which is what a filter does on the suction side. Pumps and blowers were my career for 30 years.

@Blastfact I don’t think most would be interested in the fan characteristics like you are…sounds like you got a handle on this… :cowboy_hat_face:

Just finished relocating fan and filter outside of tent to acquire more headroom and reduce hanging weight on tent frame. I won’t say it works better this way, but i’m pulling negative pressure and no stinky as of yet. I’ll finish cleaning wires up tomorrow.

Mines on the top of the tent now…
