you can pick up any 4"-8" inline fan moving about 70-500 cfm for $20-$50.. The only problem is they dont work well against static pressure. The longer your venting is and the more 90 bends you have, the less air will be moved.. works that way with any fan really but more with inlines.
greenhorngrower Reviewed by greenhorngrower on . why inline fans? I always see people mentioning inline fans and im curious as to why? i've no experience with them, i just used an old 8inch fan i had kicking around the house as my exhaust (its massive overkill for the situation but it gets the job done and then some) Are they quieter? Is it because they are easier to hook up to carbon filters? Something else perhaps? Rating: 5
