Airtac GAFC Air Service Unit GAFC300N10ALK
The AirTAC Airtac GAFC Air Service Unit GAFC300N10ALK 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC300N10ALK
This GAFC300 F.R.L. combination pairs a filter-regulator body with a lubricator on a shared T-bracket, so the air is cleaned and set to pressure before a metered oil mist is added downstream. The 3/8in port and 1020 g mass place it in the mid-range class, suitable for a single machine station or a small header feeding a few actuators.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), which suits delicate circuits that must never see a higher setpoint. The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, and the automatic drain clears water without an operator. A circular gauge with an MPa/psi scale is fitted, and the 40 um element handles standard shop air.

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 GAFC300N10ALK Is Used
Low-pressure assembly jigs
Feed a delicate clamping fixture on a workbench where the 0.4 MPa ceiling protects thin-walled parts from over-force.
Paint or coating lines
Supply a spray gun or coating head that needs a stable, low regulated pressure and a clean air supply.
Laboratory pneumatic circuits
Run a small test bench or analytical instrument that requires a gentle, consistent air pressure without spikes.
Is the Airtac GAFC Air Service Unit GAFC300N10ALK the Right Air-Prep Unit?
Choose this GAFC300N10ALK when your line needs a 3/8in port and a regulated ceiling of 0.4 MPa, not the 0.9 MPa of the standard type. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment. The automatic drain is the right call for unattended equipment, and the reverse-flow (reflux) valve is fitted as an ordering difference. The PT thread carries an MPa/psi gauge scale, and the 40 um element is the default grade. If the line must stay oil-free, omit the lubricator and select a plain GAFR300-10 filter-regulator instead; the spares for this unit are GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N10ALK FAQ
This F.R.L. combination works with air, filters to 40 um, and regulates from 0.15 to 0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g. Use ISO VG 32 oil in the lubricator.
The K indicates a reverse-flow (reflux) valve is fitted to this unit. The catalogue shows it as a separate pneumatic symbol, and it is an ordering difference you should note when comparing with a standard GAFC300. The unit still functions as a filter-regulator plus lubricator.
