Hi
I have been writing with one named Neil from red sea, and he told following information about the fans in the hood, so I just wanted to share with you.
Fan In the Hood
Size 6X6X2 cm
Dba: 20 db
RPM: 2500
CFM: 9,9
So i think that I will change them to these
SilenX Corporation - iXtrema Pro Fans
They have a flow at 10 CFM and only 8 dba
Regarding the ventilation kit, i still wait an answer from Stevie
