Fan question 🙌

**Ralf454** · 15-09-17, 10:58 PM

Hey guys, if I have a 6" rvk l1 fan pulling air through a carbon filter and I then use that air to blow through my cool tube would it then be ok to put a 4" fan right after the 6" fan to help pull the air through the tube ? Or would it just mess up the l1 fans pull ?

Putting the exact same or bigger power fan will give you more power but putting a lower power behind the higher power would in turn give u less ass the bigger one pulls in its max pull but then you be forcing it through the smaller one your technically deleting your bigger fan from the entire circuit in theory pal.... only way youl get more pull is going bigger on ur initial pull if you get me....

Or put the carbon filter before the cooltube and use your 6" to extract it through..

Carbon filter > if needed, ducting > cooltube > ducting (if needed) > 6"rvk > ducting to expel the extraction.

Kind of thing

Naa mon Just use the one mukka. Go bigger on extraction if you wana move more air.
