Efficiency of a dirty air handler fan vs a clean one
Efficiency of a dirty air handler fan vs a clean one
(OP)
Can anyone point me in the direction of a document that can summarize the effects a dirty fan have over the efficiency vs. a clean fan? A dirty fan will increase the static required to operate and if too much builds up, could create an unbalanced fan leading to premature bearing failure.
Or am i just imagining all of this?

A dirty fan wont be able to privde the flow for which it has been designed for.
and yes you are right ,,, dynamic balancing of rotating equipment is important for the wear and tear of bearings. esp if RPM is high

Would assume what happens between clean and completely fouled is anyones guess and anyway, how would you measure the degree of foulness?

From ASHRAE 62.1 (especially 5.5.1) the surfaces in the air stream are to be resistant to moisture and mildew growth. Maybe this kind of dirt is resistant to moisture and mold; where that dirt ends up should be a concern.
