About the Airtac GAFC Air Service Unit GAFC300N15ASN
This AirTAC GAFC300N15ASN is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a lubricator adds a metered oil mist downstream. With a 1/2in port and 1020 g mass, it suits medium-size machine headers where a compact footprint still needs real flow capacity.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, so service intervals are practical for a busy line. It operates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element, and the automatic drain clears water without an operator. No gauge is fitted, so the 1/8in gauge connection is ready for an add-on if you need to read set pressure.

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 GAFC300N15ASN Is Used
CNC coolant valves
Feed a 1/2in line to solenoid valves on a CNC lathe's coolant system, where regulated pressure keeps flow consistent and the automatic drain handles condensation from frequent cycling.
Assembly station headers
Supply a multi-operator assembly bench with filtered, regulated air for pneumatic screwdrivers and press tools, with the 98 cc oil bowl keeping lubricators topped up across a shift.
Packaging line actuators
Run a carton-sealing machine's cylinder bank from this unit, where the 3500 L/min flow envelope at 0.7 MPa inlet supports several 1/2in branches without pressure sag.
Is the Airtac GAFC Air Service Unit GAFC300N15ASN the Right Air-Prep Unit?
Choose this GAFC300N15ASN when a 1/2in port is the right size for your branch line. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating are identical across PC, metal, and nylon, so confirm the material suits your environment. The A code means an automatic drain, which matters most on wet or unattended lines. Standard type S regulates 0.15-0.9 MPa (20-130 psi), and the 40 um element is the default for general shop air. Since no gauge is supplied, plan to add one at the 1/8in connection if operators need to verify setpoint. Spares are orderable as GAFR300-15 and GAL300-15. 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 set your 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 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 GAFC300N15ASN FAQ
This F.R.L. combination operates from 0.15 to 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 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g. The 40 um filter element is standard for this model.
The N after the port code means no pressure gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a suitable gauge later if you need to read the set pressure directly. Until then, the regulated output is set by the adjustment knob but cannot be visually verified without an external gauge.
