About the Airtac GAFC Air Service Unit GAFC300N15ASNK
This GAFC300N15ASNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, joined on a T-bracket with quick clamps. The 1/2in port and 1020 g mass place it in the mid-size class, suitable for feeding a machine header or a small multi-station line. It delivers air filtered to 40 um and regulated to 0.15-0.9 MPa (20-130 psi), with a metered oil mist added downstream.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, so the service interval is set by how often the line is wet. The automatic drain clears water without an operator, and the reverse-flow (reflux) valve is fitted. No gauge is supplied; the 1/8in gauge connection is ready if you add one later. The catalogue flow curve is plotted to 3500 L/min at 0.7 MPa inlet, a sizing envelope rather than a rated capacity.

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 GAFC300N15ASNK Is Used
Machine Tool Header
Feed a 1/2in header on a CNC lathe or milling machine, where the automatic drain handles condensate from wet shop air and the 40 um element protects solenoid valves.
Assembly Conveyor
Supply a multi-station assembly conveyor with regulated air at 0.15-0.9 MPa, using the 98 cc oil bowl to lubricate pneumatic actuators along the line.
Packaging Line
Run a case packer or carton sealer with this 1/2in unit, where the 60 cc drain bowl and automatic drain reduce maintenance on a line running multiple shifts.
Is the Airtac GAFC Air Service Unit GAFC300N15ASNK the Right Air-Prep Unit?
Choose this model when you need a 1/2in F.R.L. set with an automatic drain and a nylon bowl. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa (145 psi) maximum and -5 to 70 C range are identical across PC, metal and nylon, so confirm the material suits your environment. The 40 um element handles standard shop air; step to the 5 um element if you feed precision valves. The PT thread carries a MPa/psi gauge scale, though this unit ships without a gauge - the 1/8in connection is there for a field-fit gauge. The reverse-flow valve is fitted per the K code. The filter-regulator and lubricator are orderable separately as GAFR300-15 and GAL300-15. If the line must stay oil-free, choose a plain GAFR instead of this lubricating set. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near maximum if you need the full 0.9 MPa 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 GAFC300N15ASNK FAQ
This F.R.L. combination operates on air at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C and it must not freeze. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and the recommended lubricant is ISO VG 32 or equivalent.
The N after the port code means no gauge is supplied; the 1/8in gauge connection is available if you add one. The K code indicates the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. The filter-regulator and lubricator are orderable as GAFR300-15 and GAL300-15.
