Ventilation Fan Direction

i bought 2 6" C.A.P. valuline blowers but i have no idea which way is which on them. if i want to mount it to be an intake which way does it face? it came with no manual so i also dont know how to mount it. anyone??

you could hook up the power and see which side sucks and which side blows.

you could always plug it in and see how it runs.

Personally I would imagine the sides you see in your thumbnails are the intake side.

good thinking. the front is the intake. thanks for the help
