Actually, there is very little. If you have particle filtration equipment, chances are you wanted to remove particles from your coolant! This is recommended because metals degrade coolant. And the smaller the particles are, the quicker they chemically interact with the coolant, causing coolant to break down on a chemical level and eventually be useless for lubrication.
You will need to change out the filter, whether it be a bag filter (as in this case) or cartridge filter depending upon how many particles your operation creates during the machining or grinding process.
Just like an oil filter in your car, or a vacuum at home, the filtering apparatus will need changing once it has filled to capacity. If it is not filled completely, but requires too much pressure to pass liquid through it, then a bigger pore size will help. If you are trying to capture chips of 25 micron (.001″), you may want to step up to a 50 micron bag, and as chips fill it, the pore size will decrease gradually. Eventually, you will capture the smaller chips.
