used inline fan +carbon filter

Discussion in 'Grow Room Design/Setup' started by pun650, Jul 5, 2012.

  1. bought a used inline fan off a guy locally, 6". he said he used it for the last 2 years continuously

    on the side it says a product number, google came up with nothing..

    on the side it says 120v 60h 45w 1900r/pm 0.37a

    he told me it was 440 cfm, which it obviously isnt.

    anywhere to find out the actual cfm? my room isnt even sealed yet, and barely a faint smell, so i dont need it atm, but wanted to help bring temps down.

    help?

  3. It looks like it could be a 440, why are you doubting it?

    With the filter on it barely made a difference temp wise. Took the filter off...money.

    Was just skeptical cuz I got the fan/filter 600w digi ballast with both bulbs and a fan speed controller for 100$

    Well that ballast looks like a Digital Greenhouse ballast from HTGSupply, so if you got it all together I'm guessing it's the fan/filter combo from HTG aswell. Here's a link. HTG Supply - A GrowBright 6" Inline Fan & Carbon Filter Combo They can also be from eBay, I've seen a few on there that look similar. Either way 99% of the 6" centrifugal fans are rated 400 something cfm.
     
  6. The fan will do better off the filter because it has no resistance. That's one of the cons of using a carbon filter. It's got to push the air through the carbon, which requires some muscle.

    I just run a 550 cfm fan hooked up to my carbon filter in my grow room. I don't hook it up to exhaust any air. I use a separate fan to do that.
     
  7. That carbon filter looks grungy. Probably plugged up. 2 years is way too old for a carbon filter, it won't scrub any air and you'll have odor issues.
     
  8. Eh, he said he's had it for 2.5 yrs and replaced the carbon just over a year ago. It still pulls, but just made me question the cfm. My grow room isn't even sealed yet, door open 24/7.

    I could prolly clean it out n replace the carbon before smell actually becomes an issue.

    Took the filter off for now anyways.

    Thx for the replies guys

    The fan in your link is 110w. Mine is 45. See how I would come to the conclusion mine isn't anywhere near 400 cfm?
