About the Airtac GAFC Air Service Unit GAFC300C15SWK
This GAFC300C15SWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket. The 1/2in port and 1020 g mass place it in the mid-size class, suited for feeding a single machine station or a small multi-axis assembly cell.
The metal bowl (C code) holds 60 cc for condensate and 98 cc for oil, and the 5 um element traps finer particles than the standard 40 um grade. Working pressure is 0.15-0.9 MPa (20-130 psi), with a max supply of 1.0 MPa (145 psi). The circular gauge reads in MPa/psi, and the semi-auto plus manual drain pair gives both automatic dumping on pressure drop and on-demand draining.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC300C15SWK Is Used
Precision valve control
Feed a bank of fine pneumatic valves on a pick-and-place unit where the 5 um element protects close-tolerance spools from wear.
Single-station conveyor
Supply a short conveyor section with a single indexing cylinder, using the 1/2in port to keep pressure stable at the actuator.
Machine tool lubrication
Add metered oil mist to a small drilling spindle's air bearing, with the 98 cc oil bowl reducing refill frequency on a busy shift.
Is the Airtac GAFC Air Service Unit GAFC300C15SWK the Right Air-Prep Unit?
Choose this GAFC300C15SWK when you need 1/2in ports and the finer 5 um filtration for sensitive valves or instruments. The metal bowl is specified by the C code; the catalogue rates all bowl materials to the same 1.0 MPa max and -5 to 70 C, so confirm the metal suits your environment rather than assuming it is tougher. The semi-auto drain clears condensate each time pressure drops, while the manual drain gives you a handle for scheduled maintenance. The fitted gauge is graduated in MPa/psi for the PT thread, and the reverse-flow (reflux) valve is included per the K code. Spare parts are the GAFR300-15 filter-regulator and GAL300-15 lubricator, both orderable separately. Since the lubricator adds oil mist, choose a plain GAFR if your line must stay oil-free. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C15SWK FAQ
The GAFC300C15SWK operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works from -5 to 70 C and should not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32, and the unit weighs 1020 g.
The C code specifies a metal bowl, a build choice you should confirm suits your surroundings since the catalogue gives no material-specific ratings. The W code means a 5 um element, which traps finer particles than the standard 40 um grade, ideal for precision equipment but requiring more frequent element service.
