Airtac GAFC Air Service Unit GAFC400C10LNK
The AirTAC Airtac GAFC Air Service Unit GAFC400C10LNK 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 GAFC400C10LNK
This AirTAC GAFC400C10LNK is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-shaped bracket. The filter and regulator share one body, so the set is two pieces instead of three, which means one less inter-unit joint to seal. Air enters the 3/8" port, gets filtered and regulated down to the 0.15-0.4 MPa (20-58 psi) range, then the lubricator adds a controlled oil mist last, downstream of the regulator seat.
The metal bowl holds 100 cc of condensate and the oil bowl holds 185 cc, so the service interval is driven by how much water your compressor pushes through. The 40 um element handles standard shop air, and the unit weighs 1810 g, which tells you it needs a proper panel or frame mount rather than support from the tubing. A reverse-flow valve is fitted, and the catalogue draws it as a separate pneumatic symbol.

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 GAFC400C10LNK Is Used
Precision pressure setting
Set a lathe chuck or a clamping fixture to a precise 0.3 MPa without worrying about the upper range, since the L type gives finer adjustment below 0.4 MPa.
Paint spray booth
Feed a spray gun at a stable low pressure, where the 40 um element keeps the line clean and the lubricator adds oil mist for the gun's moving parts.
Bench assembly station
Run a small pneumatic press or a parts feeder at a consistent low pressure, with the metal bowl handling occasional water slugs from a wet compressor line.
Is the Airtac GAFC Air Service Unit GAFC400C10LNK the Right Air-Prep Unit?
The L in this code means lower-pressure regulation, topping out at 0.4 MPa instead of the standard 0.9 MPa. If your machine might ever need more than 0.4 MPa, this is the wrong part, so check the duty cycle before ordering. The metal bowl is a build choice for the environment, but the specification does not change with it, so confirm it suits your surroundings. No gauge is supplied with this model, but the gauge connection is 1/4" if you add one later, and the PT thread means the scale would read MPa/psi. The semi-auto drain dumps condensate on each pressure drop, and the manual drain works on demand, so someone needs to attend the bowl periodically. The reverse-flow valve is fitted, and the two units are orderable separately as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C10LNK FAQ
The GAFC400C10LNK operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g.
The N in the code means no gauge is supplied, so you cannot read the set pressure directly on the unit. The gauge connection is 1/4" if you want to add one later, and the PT thread means the scale would be MPa/psi. For a lower-pressure application, adding a gauge helps the operator verify the 0.15-0.4 MPa setting.
