About the Airtac GAFC Air Service Unit GAFC20008ALW
This GAFC20008ALW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air is cleaned and set to pressure in the first body, then the lubricator meters oil mist into the flow last, so oil never passes back through the regulator seat. The 1/4in port and 590 g mass place it in the compact GAFC200 class, sized for a single actuator or a small jig rather than a machine-wide header.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum supply and 1.5 MPa (215 psi) proof pressure. The 5 um element traps fine particles for sensitive valves, and the automatic drain clears condensate from the 25 cc bowl without an operator. The circular gauge is fitted and reads in MPa and psi for the default 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 GAFC20008ALW Is Used
Precision valve actuation
Feed a single 1/4in-port pneumatic valve or small actuator on a benchtop test rig, where the 5 um element protects the spool from fine wear particles.
Portable tool lubrication
Supply a compact air tool on a service cart, using the automatic drain to clear condensate between shifts and the lubricator to keep the tool running.
Lab air preparation
Condition air for a small lab fixture that needs regulated pressure below 0.4 MPa, with the oil mist added downstream for a light-duty pneumatic clamp.
Is the Airtac GAFC Air Service Unit GAFC20008ALW the Right Air-Prep Unit?
Choose the GAFC200 body when a compact, lightweight unit is needed for a single pneumatic device. The 1/4in port suits small cylinders and valves, while the 36 cc oil bowl and 25 cc condensate bowl define the service interval. The automatic drain (A) is the right call for unattended lines, and the 5 um element (W) is worth the more frequent service if you feed precision equipment. The lower-pressure L type tops out at 0.4 MPa, so if the machine may ever need more than that, step up to the standard S type instead. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific ratings. The gauge reads MPa and psi on the PT thread. Spares are orderable as GAFR200-08 and GAL200-08. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated band.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 590 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 GAFR200-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC20008ALW FAQ
The GAFC20008ALW operates from 0.15 to 0.4 MPa (20-58 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It works from -5 to 70 C and needs ISO VG 32 lubricant. The drain bowl holds 25 cc and the oil bowl 36 cc, with a total weight of 590 g.
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 to 0.9 MPa. This suits applications that never need more than 0.4 MPa, giving finer adjustment across the lower band. If your machine might require higher pressure later, the standard S type is the safer choice.
