About the Airtac GAFC Air Service Unit GAFC40010LN
This GAFC40010LN is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a T-bracket with quick clamps. The 3/8in port and 1810 g mass put it in the mid-size class, suited for feeding a multi-axis machine or a small production line. It regulates in the lower band of 0.15-0.4 MPa (20-58 psi), with a 40 um element as standard.
The filter and regulator share one body, so air is cleaned and set to pressure before the lubricator adds a metered oil mist last. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, and with the semi-auto plus manual drain, condensate dumps on each pressure drop or on demand. No gauge is supplied; the 1/4in gauge connection is ready for one if you need to read the set pressure.

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 GAFC40010LN Is Used
Low-Pressure Assembly Tools
Feed a pneumatic screwdriver or torque tool on an assembly bench, where the 0.15-0.4 MPa range protects delicate fastening operations from over-torque.
Paint Spray Booth
Supply a paint spray gun with regulated low-pressure air, keeping the atomization consistent while the 40 um element traps particles that could mar the finish.
Lab Air Bench
Run a small pneumatic test rig or air bearing in a laboratory setting, where the lower pressure band and clean, lubricated air suit sensitive instruments.
Is the Airtac GAFC Air Service Unit GAFC40010LN the Right Air-Prep Unit?
Choose this GAFC40010LN when your application runs at low pressure, up to 0.4 MPa (58 psi). The L type tops out there, so if the machine may ever need more, select the standard S type instead. The PC bowl is the default build; confirm it suits your surroundings, as the catalogue gives no material-specific resistance data. The semi-auto and manual drain pair suits attended lines where operators can check the bowl. The 40 um element handles general workshop air; step to the 5 um W option for finer filtration. The PT thread with MPa/psi gauge scale matches common regional fittings, and a gauge can be added at the 1/4in connection. Spares are orderable 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.
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 GAFC40010LN FAQ
This F.R.L. combination operates at 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 works in -5 to 70 C temperatures and needs 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 in the code after the port means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later to read the set pressure. Without one, the outlet pressure cannot be monitored directly on the unit.
