Hi All,
I am looking into the cooling of some enclosures using fans. The
enclosures already have fans installed, and due to space constraints
they were placed in the top of the door sucking air out of the
enclosure. I was going to fit a vent with filter on the bottom of the
enclosures (opposite side) to improve air circulation. The question is:
Is it better to suck air into the enclosure or suck air out of the
enclosure?
In my mind it seems better to suck air in, because you can control the
air intake and filter it. The only problem I have is that changing it to
that configuration will be much more costly and I am not completely sure
that it is worth it.
Your opinion will be welcomed.
Best Regards
             Luis
