samiam44, screen filter? I would have to have my $100+ compressor hoses cut and fabricated for a screen filter to work.

I notice on this forum everyone wants to bash everyones flushing method and blame this for the R4 failure. In the end it may not even matter as long as you get the debris out (if it failed). Sometimes a flush is not needed if compressor does not grenade. Leave expansion valve and rec/dryer alone and button everything up real quick.
