Some comments about this we saw on the web:
* /u/checkitoutmyfriend on /r/BurningMan I used two, one for each pad, inner and outer. This way if one pump dies I still have the other pad getting water. No dry spots) Same with the fans. I one dies just tape it off. But I do carry extra pumps & fans. I also found if you flip the header tube so the holes are pointing up or slightly outward (10:00 position), then sew up a loose fitting sleeve from a tee shirt to go around the tubing, The water pressure balloons up the sleeve allowing for better water dispersion over the pads.The Media is called CoolPad Bonded paper pad. HVAC shops carry it, or can get it. Lowes and HD carry it in season, in rolls if you are making a few bins for buddies. Do all the media cutting at home as its a tad moopy. Not like Aspen pads but still moopy. Once assembled in the chicken wire cage, its good to go.
This also has a couple of float switches and a programmable timer. Being this bin is for grey water removal, I set up some simple controls to start when full, shut down pumps at low level and run the fans for a set time after that to completely dry the pads. When it fills back up it starts all over.
