a Fan+a wall

Nomad2000 · 07-15-2002, 03:40 AM

1. If you use BIX with "push-pull" 120mm Panaflo Fans (69 CFM) for horisontal airflow, at what minimal distance should the wall be so that it does not reduce the airflow?
2. Is "push-pull" really better than only "push" or "pull"?
Thank everybody.

1) Maybe 6 or 12 inches. I never noticed any effect from 6 inches, but your setup may be more sensitive.

2) Not really. Too much noise for too little gain IMO.

maybe not even 6"... the air comes out of the fan spirals outward. there's not much flow at the center. The air should just hit the wall at an angle and continue to flow outward along the wall.
