Castair C-CK10 Coalescing Filter Repair Kit -- For C-CF10 (1-inch NPT)
The Castair C-CK10 is the coalescing filter repair kit for the C-CF10 coalescing filter (1-inch NPT, 150 CFM, 250 PSI). When the bowl seal fails, the bowl cracks, or internal components wear out on the C-CF10, this repair kit lets you restore the filter body to proper working condition without buying a complete replacement unit.
Castair builds their filter lineup to be field-serviceable. Keeping repair kits in stock means you can fix a failed filter on the spot rather than waiting for a complete replacement. For shops where a downed coalescing filter means halted spray work or lost instrument air supply, that matters.
What Repair Kits Cover
- Bowl seals and O-rings: The most common failure point in coalescing filters -- seals degrade from oil exposure, pressure cycling, and temperature variation
- Bowl components: Polycarbonate bowls can crack from solvent exposure or impact
- Internal service hardware: Drain components and fittings depending on kit version
Note: The C-CK10 is a service kit for the filter body. The replacement coalescing element for the C-CF10 is the C-F9 (9000 series), ordered separately.
When to Use a Repair Kit vs. Replace the Filter
- Use the C-CK10 when: The filter housing is structurally sound but you have a seal leak, cracked bowl, or failed drain fitting
- Replace the entire C-CF10 when: The filter body itself is cracked, corroded, or damaged beyond what a seal replacement can address
Compatibility
