About the Airtac GAFC Air Service Unit GAFC300N08ASN
This AirTAC GAFC300N08ASN is a two-piece F.R.L. combination: a GA-series filter-regulator (GAFR300-08) joined to a GA-series lubricator (GAL300-08) on a T-shape bracket with quick clamps. Air is filtered and regulated in the first body, then the lubricator adds a metered oil mist last, downstream of the regulator seat. With a 1/4in port and a 1020 g mass, this unit suits a single machine station or a small panel that needs clean, pressure-set, lubricated air.
It operates in the standard 0.15-0.9 MPa (20-130 psi) range with a 40 um element. The nylon bowl is specified by the N before the port code, and the automatic drain (A) clears condensate without an operator. No gauge is supplied, so the set pressure cannot be read without adding one; the 1/8in gauge connection is ready for a later fit. The 60 cc drain bowl and 98 cc oil bowl set the service interval, and the catalogue flow curve is plotted to 3500 L/min at 0.7 MPa inlet.

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 GAFC300N08ASN Is Used
Precision jig clamping
Feed a single-station clamping jig on a CNC fixture where a 1/4in port and 0.15-0.9 MPa range give clean, regulated air to hold parts firmly without over-pressuring.
Small assembly bench
Supply a bench-top pneumatic press or a hand-operated assembly tool with filtered, lubricated air, keeping the lubricator oil mist downstream so the regulator seat stays clean.
Machine tool lubrication
Run a small spindle or slide lubrication system where the 60 cc drain bowl and 98 cc oil bowl reduce how often an operator must check levels on a busy shift.
Is the Airtac GAFC Air Service Unit GAFC300N08ASN the Right Air-Prep Unit?
Choose this GAFC300N08ASN when you need a 1/4in F.R.L. combination with an automatic drain and a nylon bowl. The nylon bowl is a build choice, not a performance upgrade: the common specification (1.0 MPa max, -5 to 70 C) is identical across PC, metal and nylon, so confirm the material suits your surroundings. The automatic drain is the key differentiator for unattended or wet lines, and the 40 um element is the standard grade; step to the 5 um W option if you feed precision valves. The PT thread carries a gauge scale in MPa/psi, but this model has no gauge fitted, so plan to add one at the 1/8in connection if operators need to read the setpoint. The two units are orderable separately as GAFR300-08 and GAL300-08, so a clogged element or damaged bowl does not mean replacing the whole assembly. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you really need 0.9 MPa out.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N08ASN FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The 60 cc drain bowl and 98 cc oil bowl are sized for a 1/4in port, and the unit weighs 1020 g. The catalogue flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The N after the port code means no gauge is supplied. The 1/8in gauge connection is already in place, so you can add a circular gauge later to read the set pressure. Until then, the pressure cannot be read directly on the unit, so plan for a gauge if operators need to verify the setpoint.
