Great info about the reduced air flow, due to 90 degree bends and reducers for scrubbers Rhizome. One of those things I know... but didn't really think about. :thumbsup:

Norkali, are you dealing with odor at the moment? If so, how well is your scrubber working? I ask because now that you are changing some intake/exhaust dimensions, I wonder how will that effect the efficiency of your carbon scrubber? I've read that you need to make sure you have adequate time for the exhausted air to pass through the carbon to work well. Rhizome, any info on maximizing the efficiency of your exhaust fan/carbon scrubber relationship? I'm guessing that since his intake and exhaust capabilities will be increased, it will cause the air to pass through the carbon faster. Hope this isn't considered a jack... thought it might help Norkali if he does experience problems when refitting. Keep :jointsmile:
