Where these bags run
Bag filtration is the same job everywhere — take the solids out before they reach the pump, the nozzle or the part. What changes is the duty. Pick the one that looks like yours.

The chemistry that goes in the tank
A bag takes the soil out once the chemistry has lifted it off the part. The bath you end up with decides which bag survives it — a pH 14 degreaser and a pH 1 descaler do not take the same media.
