PF 10 series filters
The PF-10 series filters utilized a 3rd party filter vessel for the most part. These vessels came complete to Puroflux with all internals which were typically ABS or polycarbonate. Some might consider these materials inferior to the S80 PVC internals we use on our fabricated stainless and carbon steel units. Furthermore, those internals provided with the fiberglass vessel were not capable of maintaining the finer media offerings. 10-micron media was the low limit. Just the same, with a small understanding of filtration principles you will realize decent removal results for fractional micron particles. In any case; to utilize the finer media offerings (5 and 0.5 microns) you must upgrade to the PF-20, PF-30, or PF-40 series on open applications.
Lastly, a 36” vessel is designed for 140 GPM side stream applications based on 20 GPM / ft2 flux. For applications such as full flow or single pass; we recommend a slower flux to optimize filtration media capabilities. This slower flux can be anywhere from 10 GPM to 5 GPM / ft2 flux. In essence a filter vessel two to four times larger.
