Graver's GFC™ filter cartridges are composed of FDA-listed finely woven borosilicate glass fibers that have a natural positive ionic charge. This positive charge aids in the retention of negatively charged particulates, such as colloidal material or contaminants that may result in haze or flocculation. That's why we call the GFC a haze filter. They are also an ideal filter to use after carbon filtration to catch any loose carbon fines.

GFC™ features an exceptionally high flow rate for a cartridge filter: 8 GPM per 10 inches (e.g. a 30" filter has a max flow rate of 24 GPM, 20" filter 16 GPM, and so on).

Combined with its exceptional service life, GFC makes an economical choice for wine, beer & spirits producers seeking to remove haze from their product.
