Just asking and thank you for any input and advice
All 200T manual units use a single
5 Micron pre-filter. The fully automated 200Ts use a 20 Micron and a 5 Micron. This has more to do with the sensors that read dirty filters and the pressure differentials between the two than the need for the 20 Micron for filtering. If your system is manual the single
5 Micron is perfectly fine. No need to add a 20 Micron.
