About the Airtac GAFC Air Service Unit GAFC40010L
This AirTAC GAFC40010L is a two-piece F.R.L. combination: a filter-regulator body handles both filtration and pressure control, then the lubricator adds a metered oil mist downstream. The 3/8in port and 1810 g mass place it in the mid-size class, suited to multi-actuator machines where a smaller unit would struggle.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element as standard. Its 100 cc condensate bowl and 185 cc oil bowl mean fewer service visits than smaller bodies. The circular gauge reads in MPa/psi, matching the PT thread. Max supply is 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and the unit operates from -5 to 70 C.

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 GAFC40010L Is Used
Low-Pressure Assembly Stations
Feed a bench-top pneumatic press or torque tool where the regulator is set to 0.3 MPa. The 3/8in port and 1810 g mass handle the duty without oversized hardware.
Paint Spray Booths
Supply atomizing air to spray guns at a controlled 0.25-0.35 MPa. The lower-pressure range keeps the finish consistent, and the 185 cc oil bowl keeps the lubricator running between shifts.
Lab Test Rigs
Drive small pneumatic cylinders in a test fixture at 0.2 MPa. The 40 um element protects the valves, while the semi-auto drain clears condensate without constant attention.
Is the Airtac GAFC Air Service Unit GAFC40010L the Right Air-Prep Unit?
Choose this GAFC40010L when your application needs a regulated band capped at 0.4 MPa (20-58 psi). The L type suits low-pressure circuits, but if the machine may ever require more than 0.4 MPa, select the standard S type instead. The PC bowl is the default build; confirm it suits your environment, as the catalogue gives no material-specific ratings. The semi-auto drain dumps condensate on pressure drops, with a manual override for on-demand use.
The 3/8in port pairs with the GAFC300 (1/4in-1/2in) below and the GAFC500 (3/4in) above. The 40 um element handles general shop air; upgrade to the W code for 5 um filtration if you feed precision valves. The PT thread carries an MPa/psi gauge scale. 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, so plan your 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 GAFC40010L FAQ
The GAFC40010L 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). It works in temperatures from -5 to 70 C. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Use ISO VG 32 oil in the lubricator.
The L type is designed for circuits that never need more than 0.4 MPa (58 psi), such as certain spraying or low-force clamping applications. It gives finer adjustment within that band. If your machine might need higher pressure later, choose the standard S type (0.15-0.9 MPa) instead, as the L type cannot be modified.
