Overview
Overview
Cartridge length × outside diameter: 10-inch length class; outside diameter unverified. Partial or unverified dimensions. Nominal size classes may differ from measured end-to-end dimensions.
FT-FTC-20BB is the 20-micron cartridge in Spectra’s commercial Big Blue prefilter pair. It captures the coarser sediment before water enters the downstream 5-micron element.
The Farallon Connect parts drawing identifies FT-FTC-20BB and FT-FTC-5BB in separate FT-FTH-10BC3P1 housings. The installation section places this filter module between the boost pump and the high-pressure module.

Match the commercial housing and its assigned 20-micron position. FT-FTC-20 is the smaller standard cartridge; sharing a micron rating does not make the two housing sizes interchangeable.

FAQs
Can the two filter ratings be swapped?
The Farallon manual specifically places 5 microns downstream of 20 microns. Keep that order when installing new elements; the housing size alone does not identify which rating belongs there.
