Yes, there is a formula. 90 cfm for each 400w reflector, 125 cfm for each 600w reflector, and 200 cfm for each 1000w reflector. Most 6" fans are around 400 cfm, so you'd be good with one of those.
No problem, glad I could helpSweet, thank you sir! + 1 on the rep for you. Very helpful.
Hi MsJazzy. An inline fan (blower) is for exhausting the room or the reflectors, or for using a carbon filter inside the room. A booster fan is meant to be used in the middle of the series of reflectors somewhere just to keep the air moving and give it a little "boost" in the right direction. However booster fans aren't strong enough to pull air through a reflector or a carbon filter on it's own.I am so confused about the differences of fans.. Booster vs. inline?? Sorry.. i just ordered a 6" inline fan and just trying to learn.
