[Elecraft] OT: The Great KPA Fan Mystery

[Clay Autery]

With a little searching online, you can find ultra-fine dust screens 
that do not reduce volume too much.... that are also very thin, and can 
be temp mounted on the intake vents without radically injuring the 
aesthetics.

IF you care less about aesthetics and more about performance, I can 
point you in the right direction to constructing an intake filter 
assembly from OTS parts that will trap 90%+ of the pairborne 
particulates with less than 3% volume and air velocity reduction.
Better than that IF you are willing to pay the prices...

BEST practices is to leave Wayne and Eric's creation alone, and simply 
crack her open every 3 months and blow her out (CAREFULLY) with CLEAN 
and DRY air...

73,
