About the Airtac GAFC Air Service Unit GAFC300N15SNW
This AirTAC GAFC300N15SNW is a two-piece F.R.L. combination: the filter and pressure regulator share one body, and the lubricator is mounted on a T-bracket beside it. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added downstream, so oil never travels back through the regulator seat. The 1/2in port and 1020 g mass place it in the mid-size class, suited to a machine header or a small multi-station line.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element that traps finer particles than the standard 40 um grade. The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, and the catalogue flow curve plots to 3500 L/min at 0.7 MPa inlet. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection.

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 GAFC300N15SNW Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves from fine particles, while the regulator holds a stable setpoint for consistent actuation on a small assembly station.
Machine tool lubrication
Feed a metered oil mist to slide ways or spindle bearings on a mid-size machine tool, with the 98 cc oil bowl reducing refill frequency during long shifts.
Multi-station test rig
Supply a 1/2in header on a laboratory test rig, where the 3500 L/min flow envelope at 0.7 MPa inlet supports several actuators running simultaneously.
Is the Airtac GAFC Air Service Unit GAFC300N15SNW the Right Air-Prep Unit?
Choose the GAFC300 body for a 1/2in port with a 60 cc drain bowl and 98 cc oil bowl, weighing 1020 g. The nylon bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm nylon suits your environment. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use. The 5 um element suits precision valves or instrument air but needs more frequent service than a 40 um element. The PT thread carries a gauge scale of MPa/psi, though no gauge is fitted here. The two units are orderable separately as GAFR300-15 and GAL300-15, so a clogged element does not mean replacing the whole assembly. If the line must stay oil-free, choose a plain GAFR filter-regulator instead of this lubricating set. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan 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 GAFC300N15SNW FAQ
The GAFC300N15SNW operates at 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g with a 1/2in port.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC300 body is 1/8in, so you can add a compatible gauge later if you need to read the set pressure directly at the unit.
