About the Airtac GAFC Air Service Unit GAFC400N15ALW
This AirTAC GAFC400N15ALW is an F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body that cleans the air and sets its pressure, followed by a lubricator that adds a controlled oil mist. The 1/2in port and 1810 g mass place it in the mid-size class, suited for feeding a machine header or a small multi-station line rather than a single actuator.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade. The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, so the service interval is driven by how often the line is wet. A circular gauge is fitted, reading in MPa and psi for the PT thread.

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 GAFC400N15ALW Is Used
Precision valve control
The 5 um element protects fine pneumatic valves on a small assembly station, while the lower-pressure range suits delicate grippers that must not see full shop pressure.
Machine header feed
A 1/2in port and 1810 g mass let this unit feed a compact machine header, supplying filtered and lubricated air to several cylinders from one central point.
Low-pressure test rig
For a bench test rig that needs regulated air below 0.4 MPa, this combination delivers a clean, oil-misted supply with the automatic drain handling condensate from the receiver.
Is the Airtac GAFC Air Service Unit GAFC400N15ALW the Right Air-Prep Unit?
The GAFC400 body offers 3/8in and 1/2in ports; this 1/2in version sits above the GAFC300's 3/8in option and below the GAFC500's 3/4in port. The nylon bowl is a build choice, but the common specification of 1.0 MPa max and -5 to 70 C does not change with material, so confirm it suits your surroundings. The automatic drain clears condensate without an operator, and the 5 um element suits precision valves but will need service sooner than a 40 um grade. The L type tops out at 0.4 MPa, so if the machine may ever need more pressure, this is the wrong part. The circular gauge reads MPa and psi, matching the PT thread. Spares are orderable as GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so the regulator has room to work.
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 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N15ALW FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The N before the port code specifies a nylon bowl for the condensate and oil reservoirs. The catalogue gives no impact or chemical resistance data for the material, so confirm it suits your environment. The common specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material.
