Castair C-CK34 Coalescing Filter Repair Kit -- For C-CF34 (3/4-inch NPT)
The Castair C-CK34 is the coalescing filter repair kit for the C-CF34 coalescing filter (3/4-inch NPT, 120 CFM, 250 PSI). When a bowl seal fails or internal components wear out on the C-CF34, this repair kit lets you service the filter body without buying a complete replacement unit. Keeping a C-CK34 on the shelf means a failed seal does not shut down a spray booth or instrument air line while you wait for parts.
The replacement coalescing element for the C-CF34 is the C-F7 (7000 series). If the DPI indicator triggered, you need the element, not the repair kit. If you have a bowl leak or cracked bowl, you need the C-CK34 repair kit.
When to Use the C-CK34 Repair Kit
- Bowl seal failure: Air leaking at the bowl-to-body junction -- O-ring or seal has degraded
- Cracked bowl: Polycarbonate bowls can crack from solvent exposure or impact
- Drain component failure: Manual or auto drain fittings that have seized or are leaking
