Charcoal Filter Question

Can you push air or only pull air through the filter?

I know they are designed to pull air through, but never tried it the other way. If it does slightly work, I would think it would severely lower the CFM processed by said filter.

My first charcoal filter I made I pushed air threw it. It did work but not as good. Depending on how it is set up you end up not moving as much air as you need. Pulling is better the pushing. Unless you have a large blower or a high rate inline

I am just wondering if I could put it at the end of the line "up in the attic" and it blow out fresh filtered air.

This is the layout on paper.

With the filter in the flower tent the air is being restricted and causing more air to pull from the veg room. My thoughts is to disconnect the filter and if possible put it on the other side of the line and blow out through it.

If that is going to cause problems then. I will have to bite the bullet and get another fan and run another line. Which means I wasted money and have to spend more. 400 CFM inline fan.

Yes I would use 2 separate fans.

Also you wont need a 1000watt bulb if your only doing 4 plants.

I am guessing your area isnt that big and you may run into problem. a 600 watt can cover an area of up to 4x4 which is 16 sq feet. If your area is 5x5 or bigger I would go with the 1000 watt bulb. Just trying to save ya some cash and some heating problems.

i have a dimmable ballast. could I kick it to 75% which should equal 750 and be ok? i may put one in the middle and have 5 in there. i already have a 1000 watt

Obviously both, although some models only come with a flange on one side. The polarity could be reversed. If you look at a filter you buy its carbon size gets smaller from outside in. Even though it's charcoal, remember its not ultra clean. Wallmart has charcoal and I made mine.i found 2 ozone generations and if you have one of those in thevSEP room your filters in, then it works.

Hey I was talking about the fan. Sorry I'm blue dreaming

Yes you can, I have been using a Can Filter 33 plus 6 inch inline fan setup for years and it works fantastically. Ive pushed and pulled air through the filter, and while they recommend pulling air through, I have not had any complaints either way. However, a big downside to pulling air through the filter is that you must make sure that every seal between the filter and fan is completely air tight because if not, negative pressure will suck air into the seal thereby bypassing the filter. If your setup is better suited to having air pushed through the filter, you should be perfectly fine.

I just want to be perfectly clear. If I take my filter from where it is "see pic above" and put in on the push side of the 400 cfm inline fan, thats is in the attic, it will be ok and fix my problem?
