Hey friends sorry i haven't been on. i been real busy working on my room here is a little update on it. can any of you guys tell me how to improve my air cooled hoods , air flow, i have a 6in hyper fan on it.
Reducing ducting length will improve fan efficiency.
Eliminating 90 degree and sharper bends will also help. The fewer bends the ducting has, the better efficiency you'll have.
Reducing filter restriction will improve efficiency, but may reduce filter effectiveness.
And last but not least, upgrading the fan to a more powerful unit with a higher CFM rating will help as well.
