We used to use a unit twice the size in a large facility many years ago.
The screens were 36X40" with lots of emulsion, and if your chemical breaks it down
well enough the paper filter won't clog much at all. One tech mentioned when emulsion
builds up on the filter it sticks to itself which helps trap more. All you do is
rip off more filter like paper towel and keep rolling. Neat stuff, simple and very efficient.
