Spectra Watermakers 20 MICRON BIG BLUE FILTER CARTRIDGE (10") FT-FTC-20BB
$33.00
Overview
Overview
Cartridge length × outside diameter: 10 × 4 inches. Manufacturer nominal length × outside diameter. Nominal size classes may differ from measured end-to-end dimensions.
FT-FTC-5BB is the fine sediment cartridge for the commercial Big Blue prefilter arrangement. Spectra specifies a 5-micron, nominal 4 × 10-inch pleated polyester element.
The Farallon Connect drawing pairs it with FT-FTC-20BB in separate housings. The 20-micron stage comes first; this 5-micron stage removes finer particles before the high-pressure module. The flush-water carbon filter is a separate circuit.

Use the commercial-size housing and the 5-micron position. The standard FT-FTC-5 is narrower even though its rating and nominal length match; compare the housing drawing, not only “5 micron.”

FAQs
Can I clean and reuse it?
The Farallon maintenance procedure says to discard the used cartridges and install new 20- and 5-micron elements. It also says to service the prefilters as the filter-condition graph rises, before repeated “Replace” indications stop the system.
