Airtac GAFC Air Service Unit GAFC300N10ALNK
The AirTAC Airtac GAFC Air Service Unit GAFC300N10ALNK 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 GAFC300N10ALNK
This GAFC300 unit pairs a filter-regulator body with a separate lubricator on one T-bracket, so the air is cleaned and set to pressure in the first body before a metered oil mist is added downstream. The 3/8in port and 1020 g mass place it in the mid-size class, and the lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi) with a 40 um element.
The nylon bowl is specified by the N before the port code, and the automatic drain clears condensate without an operator. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The reverse-flow valve is fitted, and the two bowls hold 60 cc for condensate and 98 cc for oil.

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 GAFC300N10ALNK Is Used
Low-pressure assembly tools
Feeds pneumatic screwdrivers and torque tools on a bench assembly line where the regulated band stays below 0.4 MPa to protect delicate fasteners.
Lab air circuits
Supplies filtered, lubricated air to a small laboratory test rig with actuators that must not see pressure spikes above the 0.4 MPa ceiling.
Packaging machine controls
Powers a film-sealing station's cylinders and grippers where the lower pressure range keeps film tension consistent without over-stretching.
Is the Airtac GAFC Air Service Unit GAFC300N10ALNK the Right Air-Prep Unit?
Choose this GAFC300N10ALNK when the line needs 3/8in ports and a regulated band that tops out at 0.4 MPa, which suits low-pressure circuits rather than general shop air. The automatic drain suits unattended operation, while the nylon bowl is a build choice - confirm it matches your surroundings since the catalogue gives no material-specific ratings. The 40 um element handles standard shop air, and the PT thread carries a gauge scale in MPa/psi if you add a gauge later. The two units are orderable separately as GAFR300-10 and GAL300-10.
A 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so this lower-pressure unit has generous inlet headroom for stable regulation.
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 GAFC300N10ALNK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 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, it uses ISO VG 32 lubricant, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g.
The N after the port code means no gauge is supplied, so you would need to add one to the 1/8in gauge connection to read the set pressure. The K indicates the reverse-flow valve is fitted, which the catalogue shows as a separate pneumatic symbol.
