About the Airtac GAFC Air Service Unit GAFC40010LWK
This AirTAC GAFC40010LWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added downstream, so oil never travels back through the regulator seat. The 3/8in port and 1810 g mass place it in the mid-size class, where a proper panel mount is expected rather than support from the tubing.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade. A circular gauge is fitted with an MPa/psi scale, and the 100 cc condensate bowl plus 185 cc oil bowl define the service interval. The reverse-flow valve is fitted as an ordering difference, and the two units are separately orderable as GAFR400-10 and GAL400-10.

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 GAFC40010LWK Is Used
Precision Fixture Clamping
Feed a 3/8in line to a precision clamping fixture where the lower 0.15-0.4 MPa range protects delicate workpieces from over-force. The 5 um element keeps fine particles from reaching sensitive clamp valves.
Laboratory Air Supply
Supply a lab bench with filtered and regulated air for pneumatic actuators on test equipment. The 5 um filtration and lower pressure range suit instruments that need gentle, consistent actuation.
Light Packaging Machinery
Run a light packaging line's pneumatic sensors and small cylinders at a controlled lower pressure. The 185 cc oil bowl supports extended operation between lubricator refills.
Is the Airtac GAFC Air Service Unit GAFC40010LWK the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port and 1810 g mass suit the machine, with the 100 cc drain bowl and 185 cc oil bowl setting the attendance schedule. The PC bowl is the standard build; confirm it suits the surroundings, since the catalogue gives no material-specific ratings. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use. The 5 um element is for finer filtration, but expect more frequent element service than a 40 um grade. The PT thread carries an MPa/psi gauge scale, and the lower-pressure L type tops out at 0.4 MPa, so verify the application never needs more. The reverse-flow valve is fitted per the K code. For oil-free lines, omit the lubricator and choose a plain GAFR filter-regulator instead. With a 1.0 MPa max supply, there is about 0.6 MPa above the 0.4 MPa top of the 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 GAFC40010LWK FAQ
The GAFC40010LWK 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 uses ISO VG 32 lubricant. The unit weighs 1810 g, has a 100 cc drain bowl and a 185 cc oil bowl, and uses a 5 um filter element.
The K code indicates the reverse-flow (reflux) valve is fitted. The catalogue shows this as a separate pneumatic symbol. The two main units are a GAFR400-10 filter-regulator and a GAL400-10 lubricator, both with the same 3/8in port.
