About the Airtac GAFC Air Service Unit GAFC40010LW
This GAFC40010LW is a two-piece F.R.L. combination rated for a lower pressure band of 0.15-0.4 MPa (20-58 psi). The first body houses the filter and the regulator together, so the 3/8in air is cleaned and set to pressure before it moves on. The second body is the lubricator, which meters ISO VG 32 oil mist into the airstream last, keeping oil away from the regulator seat.
The 5 um element traps finer particles than the standard 40 um grade, which suits precision valves or instrument circuits that need cleaner air. With a 100 cc condensate bowl and a 185 cc oil bowl, this 1810 g unit needs less frequent attention than smaller bodies in the GAFC range. 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 GAFC40010LW Is Used
Precision pressure control
Feed a sensitive pneumatic positioner or a precision grinding spindle with a stable 0.15-0.4 MPa supply, where the finer 5 um element protects close-tolerance components.
Low-pressure packaging lines
Run a film-sealing or carton-erecting station that operates below 0.4 MPa, using the lower-pressure regulator to avoid over-pressurizing delicate grippers or sensors.
Instrument air circuits
Supply a lab analyzer or a pneumatic test fixture that requires cleaner air and a modest pressure ceiling, with the 5 um element filtering out fine particulates.
Is the Airtac GAFC Air Service Unit GAFC40010LW the Right Air-Prep Unit?
Choose the GAFC400 body for a 3/8in line that needs a 6000 L/min flow envelope at 0.7 MPa inlet, as plotted in the catalogue curve. The L type tops out at 0.4 MPa, so if your machine may ever need more than that, select the S type instead. The PC bowl is the standard build; the C or N codes change the material without altering the -5 to 70 C rating, so confirm compatibility for your surroundings. The blank drain code means both a semi-auto drain and a manual drain are fitted, giving you a backup for condensate removal. The 5 um element is the finer filtration choice, but it will need more frequent service than a 40 um element. The PT thread comes with a gauge scaled in MPa and psi. Replacement units are orderable as GAFR400-10 and GAL400-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so you have ample inlet headroom for this lower-pressure regulator.
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 GAFC40010LW 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 a proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g. The 3/8in port and 5 um element make it suitable for cleaner, lower-pressure duties.
The L in the code specifies the lower-pressure type, which regulates from 0.15 to 0.4 MPa instead of the standard 0.15-0.9 MPa. This is for applications that need a precise, lower ceiling and do not require higher pressures. If your process might need more than 0.4 MPa, choose the S type instead to avoid replacing the unit later.
