Thanks for all your great responses.
I decided to put the blower after the heat exchanger and pads so it goes like this:
heat exchanger -> pads -> blower -> ducts
I decided that it was best to err on the side of caution, so I did it the traditional way. I included a few pics so you can see...
This is what the blower looks like.

To be more exact, then I should have the heat exchanger and the pads in front of the blower so the blower pulls air through them to achieve maximum cfm?
The heat exchanger in particular is causing a noticable pressure drop.
Thank you Chris!
So if I understand you correctly, I will get exactly the same flow rate regardless of where I position the blower?
The whole reason I'm trying to move the blower to the front is because the motor may be adding about 300 watts of heat to the system AFTER the air is humidified...
Hi:
I'm building a swamp cooler for my attic, and I'm considering where to position the blower. I could position it as the first thing in the system before the heat exchanger, the pads and the ducts. Or I can position it after the heat exchanger and the pads, so it sucks air through them...
