About the Airtac GAFC Air Service Unit GAFC40010ALNWK
This GAFC40010ALNWK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a lubricator adds a controlled oil mist downstream. With a 3/8in port and 1810 g mass, it suits mid-size machine headers where several actuators draw from one prepared air supply.
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 automatic drain clears condensate from the 100 cc bowl without operator attention, while the 185 cc oil bowl keeps the lubricator running between refills. No gauge is supplied; the 1/4in gauge connection allows adding one later.

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 GAFC40010ALNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine with 5 um filtered air, keeping fine particles away from spool surfaces.
Machine tool lubrication
Supply a controlled oil mist to slide ways and bearings on a CNC lathe, with the automatic drain handling condensate from a wet shop line.
Test bench air prep
Prepare air for a laboratory test bench where lower pressure up to 0.4 MPa is the working limit, and the 100 cc bowl handles moderate condensate loads.
Is the Airtac GAFC Air Service Unit GAFC40010ALNWK the Right Air-Prep Unit?
For a 3/8in port line, the GAFC400 body sits between the GAFC300 (1/2in max, 60 cc drain bowl) and the GAFC500 (3/4in, 108 cc drain bowl). The lower-pressure L type tops out at 0.4 MPa, so if your machine may need more than that, choose the standard S type instead. The automatic drain suits wet or unattended lines, while the 5 um element is for precision valves but needs more frequent service. The PC bowl is the standard build; confirm it suits your environment. The reverse-flow valve is fitted per the K code. Spares are GAFR400-10 and GAL400-10. Max supply 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 GAFC40010ALNWK FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The N after the port code means no gauge is supplied; the 1/4in gauge connection is there if you add one. The K code means a reverse-flow valve is fitted, which the catalogue shows as a separate pneumatic symbol. The filter and regulator share one body, with the lubricator as the second unit.
