Recycled air

  1. Hey,

    I have cyntrifical fan pulling air through a carbon filter, the air that's expelled from the fan is fairly well cooled..

    Can I duct that air back into the cab blowing over the HPS bulb to help keep the cab cooler?

  2. So you are sucking out hot clean air and want to pump it right back in.
    I don't see how you have much to gain.
  3. The air is cool once it's been thru the filter and fan.. Push that cool air back in over the bulb.. If the recycled air was hot then I wouldn't bother.
  4. What I'm thinking is whether the quality of oxygen in the air is lowered from being recycled..
