Hi all, I'm having a Kaiser compressor producing compressed air for my garage. I've installed a FRL unit at point of use. I understand that the filter medium adsorbs atmospheric dust, moisture and oil particles in compressed air. Gradually the pressure drop across the filter builds up and I need to replace the filter element. Are there any equations which help me build a model for an ideal case, so that I can analyze the conditions that lead to failure of the element? My point of use equipment is really sensitive to moisture and begins rusting easily. If I develop an ideal model, and predict when my filter would fail, I can prevent my end use equipment breakdown! Thanks!
