Airtac GAFC Air Service Unit GAFC30015SK
The AirTAC Airtac GAFC Air Service Unit GAFC30015SK is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC30015SK
The GAFC30015SK is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-shape bracket. With a 1/2in port and a 1020 g mass, this unit suits medium-duty machine builds where a panel or frame mount is expected rather than tubing support. The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 40 um element handles typical shop air.
Air enters the first body where the filter element removes solids and moisture while the regulator sets the pressure; the lubricator then adds a controlled oil mist downstream. Because the filter and regulator share one body, the assembly has one less inter-unit joint to seal compared to a three-piece train. The 60 cc condensate bowl and 98 cc oil bowl define the service interval, and the circular gauge reads in MPa and psi.

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 GAFC30015SK Is Used
Machine tool lubrication
Feed a 1/2in line to a small machining center's way lubrication system, where the 40 um element protects metering valves and the lubricator delivers ISO VG 32 oil to slideways.
Assembly station air prep
Supply a multi-fixture assembly bench with cleaned, regulated air and a fine oil mist for pneumatic screwdrivers and torque tools, keeping the 60 cc bowl visible for routine checks.
Packaging line actuators
Run a carton-forming machine's cylinder bank from this unit, using the manual drain for scheduled condensate removal and the gauge to verify the setpoint stays at 0.6 MPa.
Is the Airtac GAFC Air Service Unit GAFC30015SK the Right Air-Prep Unit?
Choose the GAFC30015SK when your line needs 1/2in ports and a standard 0.15-0.9 MPa (20-130 psi) regulation band. The PC bowl is the default build; the catalogue gives no impact or chemical data, so confirm it suits your environment. This model ships with both a semi-auto drain that dumps on pressure drop and a manual drain for on-demand use, plus a 40 um element. The PT thread carries a gauge scale in MPa and psi, and the reverse-flow (reflux) valve is fitted as an ordering difference. The two units are orderable separately as the GAFR300-15 filter & regulator and the GAL300-15 lubricator.
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, so plan the inlet pressure accordingly if you need the full band.
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 GAFC30015SK FAQ
The GAFC30015SK operates from 0.15 to 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). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The K indicates the reverse-flow (reflux) valve is fitted. The catalogue draws it as a separate pneumatic symbol with details on its own page. This model also includes a circular gauge reading MPa and psi, and the PT thread is standard.
