About the Airtac GAFC Air Service Unit GAFC30015S
The GAFC30015S is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-bracket, using quick clamps for mounting. The filter and regulator share one body, so this 1/2in unit delivers all three functions in just two pieces, reducing the number of inter-unit seals compared to a three-body train. Air is cleaned and set to pressure first, then the lubricator adds a controlled oil mist downstream, so oil never travels back through the regulator seat.
This standard-pressure model operates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element. The 60 cc condensate bowl and 98 cc oil bowl give a reasonable service interval for a 1020 g unit, while the circular gauge with an MPa/psi scale shows the setpoint. The catalogue flow curve plots to 3500 L/min at 0.7 MPa inlet, which helps when sizing for a specific duty point.

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 GAFC30015S Is Used
Machine tool lubrication
Feed a 1/2in line to a lathe's tool changer, where the filter removes moisture and the regulator holds 0.5 MPa for the clamping cylinders while the lubricator oils the slide ways.
Packaging line actuators
Supply a multi-station packaging conveyor where several 1/2in branches feed pusher cylinders, keeping the air clean and lubricated for consistent cycle times.
Assembly station air prep
Prepare air for a bench assembly station with pneumatic screwdrivers and small presses, where the 60 cc bowl handles typical condensate between shifts.
Is the Airtac GAFC Air Service Unit GAFC30015S the Right Air-Prep Unit?
Choose the GAFC30015S when you need a 1/2in port with the standard 0.15-0.9 MPa (20-130 psi) range and a PC bowl. The blank drain code means both a semi-auto drain, which dumps condensate when pressure drops, and a manual drain for on-demand use are fitted. The 40 um element suits general shop air, while the W option upgrades to 5 um for finer filtration. PT threads come with an MPa/psi gauge scale, and the K option adds a reverse-flow valve. The filter-regulator and lubricator are orderable separately as GAFR300-15 and GAL300-15, so a damaged bowl or clogged element does not require replacing the whole assembly. With a 1.0 MPa max supply, there is only about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan for a supply near 1.0 MPa 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 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 GAFC30015S FAQ
The GAFC30015S works with air, filters to 40 um, and regulates from 0.15 to 0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g. Use ISO VG 32 oil in the lubricator.
The GAFC30015S combines a filter and regulator in one body, then adds a lubricator on a shared bracket. This means you get filtering, pressure control, and oil mist in two units instead of three, so there is one less joint to seal. The filter-regulator is the GAFR300-15 and the lubricator is the GAL300-15, both orderable separately.
