Castair C-F7 Coalescing Filter Element -- 7000 Series, Fits C-CF12 and C-CF34
The Castair C-F7 is a 0.01-micron coalescing filter element for 7000 series Castair coalescing filters -- specifically the C-CF12 (1/2-inch NPT, 105 CFM) and C-CF34 (3/4-inch NPT, 120 CFM). It replaces the coalescing media when the DPI on the filter housing shows the element is loaded, or when scheduled maintenance calls for an element change. One element part number serves both filter sizes, which simplifies parts stocking.
