About the Airtac GAFC Air Service Unit GAFC400C15S
The GAFC400C15S is a two-piece F.R.L. combination: the filter and regulator share one body, and a lubricator is mounted downstream on a T-bracket with quick clamps. With a 1/2in port and 1810 g mass, it suits medium-size machine headers where a proper panel mount is expected rather than support from the tubing.
Air enters the first body where solids and moisture are removed and pressure is set to 0.15-0.9 MPa (20-130 psi). The lubricator then adds a metered oil mist as the final step, so oil never travels back through the regulator seat. The 40 um element handles standard shop air, and the metal bowl is specified by the C code; the shared -5 to 70 C and 1.0 MPa maximum apply regardless of bowl material.

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 GAFC400C15S Is Used
Machine tool coolant systems
Feed a 1/2in header on a CNC lathe or milling center where the regulator holds 0.4-0.6 MPa for clamping cylinders and the lubricator oils slide ways.
Assembly line transfer stations
Power pneumatic pushers and lift assists on a mid-size assembly line, with the 100 cc condensate bowl handling moisture from a busy compressor.
Packaging equipment air prep
Supply a carton erector or case sealer where consistent pressure and oil mist keep pneumatic actuators cycling reliably through a shift.
Is the Airtac GAFC Air Service Unit GAFC400C15S the Right Air-Prep Unit?
Choose the GAFC400C15S for a 1/2in line needing filtration, regulation and lubrication in a compact two-piece layout. The metal bowl is a build choice; confirm it suits your environment since the catalogue lists no impact or chemical data for bowl materials. This model ships with both semi-auto and manual drains - the semi-auto dumps condensate when pressure drops, while the manual drain gives on-demand control. The circular gauge reads in MPa and psi for the default PT thread, and the 40 um element is the standard grade; select the W option for 5 um filtration if finer particles are a concern. Spare units are orderable as the GAFR400-15 filter-regulator and the GAL400-15 lubricator, so a worn element or damaged bowl does not force a full assembly replacement.
A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near the maximum if you need the full output.
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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15S FAQ
The GAFC400C15S operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The C code specifies a metal bowl for both the filter and lubricator sections. The catalogue lists the same 1.0 MPa maximum and -5 to 70 C range for all bowl materials, so the metal is a build choice rather than a performance upgrade. Confirm it suits your specific surroundings, as no impact or chemical resistance data is published.
