For exhaust, that 265 is just about perfect, and that's what it would be... The can would be scrubbing the exhaust. They want a higher CFM for a recirc scrubber, because the air has to move twice as fast to keep the smell down inside the cab, vs. a -neg pressure exhaust fan. That's perfect!Beautiful drawing !
I will look at the can specs and see if it works. Thanks
Edit: the filter is 450 cfm for scrubbing and it says to divide by 2 for exhaust, which is 225.
Note... it's being used for EXHAUST in the example plan above. remember 265 out means ~265 in... yeah, it'll be a little tiny bit unbalanced, but that will create a -neg pressure enviro inside, keeping the smell in, and scrubbing the air as it is pulled out. you want the slower flow to treat the air better as it passes through the filter ((just once)) and to the outside, rather than passing through the fan several times, over and over in a recirculation scenario.I would get a fan rated closer to the filters cfm rating.
The 265 is too small for that filter. I think they mean divide the fan cfm by 2
