The SMC C2SF-2-A is the size-20 metal replacement bowl assembly for SMC compressed-air filters and separators. It swaps in for a cracked, clouded, or chemically attacked bowl on AF20 air filters, AFM20 mist separators, AFD20 micro mist separators, and AW20 filter-regulators, restoring a proper seal and reliable condensate collection. The rugged metal bowl is built for demanding environments where polycarbonate bowls fail early - wash-down bays, high-vibration lines, and stations exposed to solvents or aggressive cleaning chemicals.

Why the metal bowl

• Chemical and solvent resistant. Stands up to detergents, cutting fluids, and cleaners that craze and degrade clear polycarbonate bowls.
• Impact and vibration tolerant. Handles knocks and constant line vibration without cracking, for longer service intervals.
• Full operating range. Rated to the unit's complete pressure and temperature envelope with a secure, leak-free seal.
• Note: the metal bowl is opaque, so the condensate level is not visible. Drain on a schedule, or pair with an automatic drain for hands-free discharge.

Compatibility

Fits SMC body size 20 air preparation units: AF20 air filters, AFD20 micro mist separators, AFM20 mist separators, and AW20 filter-regulators. Manual drain cock, metal bowl, bowl seal included. Confirm the size against your unit's model code before ordering.

Specifications

Frequently serviced together

The bowl catches the water, but a complete service usually means these too:

• Filter element (AF20P-060S) - the media that actually traps oil and particulate. SMC recommends replacing it roughly every 2 years or before pressure drop reaches 0.1 MPa.
• Automatic drain (AD17) - hands-free condensate discharge, ideal for high-humidity and wash-down environments where manual draining is a chore.
• Spare bowl seals (C2SFP-260S) - keep a few on the maintenance shelf for future rebuilds.

Common questions

What does the C2SF-2-A fit?
It is the size-20 metal bowl for SMC AF20, AFD20, and AFM20 filters and separators, and AW20 filter-regulators. Confirm the size against your unit's model code before ordering.

Is the bowl seal included?
Yes. The assembly comes with the C2SFP-260S bowl seal, so you have everything needed for the swap.
