Right ill keep this short. I have purchased this carbon filter

Flow rating 175m3/hr
Filter size 19cm diameter by 25cm length ( excluding neck )
Will a extraction fan of 85m3/h attached directly to the carbon filter be sufficient to expell out the air, is it too weak or too strong?
Imo i thought it might be too weak so i was going to purchase an inline extraction fan as such:

with Up to 137 m3/h airflow output, however it states it is not foruse with carbon filters. somebody please tell me what fan I need?

+ rep

ps help a fellow grower in need for the sake of the security of my girls
