Airtac GAFC Air Service Unit GAFC20008ALWK
The AirTAC GAFC Air Service Unit GAFC20008ALWK is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/4" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC20008ALWK
This AirTAC GAFC20008ALWK is a compact F.R.L. combination built as two joined bodies: a filter-regulator and a lubricator mounted on a shared T-bracket with quick clamps. The 1/4in port and 590 g mass place it in the smallest GAFC size class, suited for a single jig or one actuator rather than a machine-wide header. Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure to the lower 0.15-0.4 MPa (20-58 psi) band, then the lubricator meters ISO VG 32 oil mist into the downstream flow.
The automatic drain clears condensate from the 25 cc bowl without operator attention, while the separate 36 cc oil bowl sets the refill interval. A circular gauge is fitted, graduated in MPa with a psi ring for the default PT thread. The reverse-flow (reflux) valve is fitted as an ordering difference. The 5 um element suits precision valves but will load faster than the standard 40 um grade, so plan more frequent element service.

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 GAFC20008ALWK Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a benchtop assembly fixture with 1/4in tubing. The 5 um element protects the clamp's fine seals, and the lower pressure range prevents over-clamping delicate parts.
Laboratory Air Supply
Supply a small lab bench station that runs a single air-operated stirrer or a miniature cylinder. The 0.15-0.4 MPa band keeps forces low, and the automatic drain keeps the 25 cc bowl clear during long experiments.
Maintenance Workbench
Power a portable rivet setter or a small blow-off nozzle on a maintenance cart. The compact 590 g body mounts easily to a frame, and the 36 cc oil bowl supports intermittent duty without frequent refills.
Is the Airtac GAFC Air Service Unit GAFC20008ALWK the Right Air-Prep Unit?
Choose the GAFC200 body when your line is 1/4in or smaller and the load is a single cylinder or small fixture; the GAFC300 with its 3500 L/min envelope at 0.7 MPa inlet is the step up if you need more margin. The L type tops out at 0.4 MPa, so if the machine may ever require more than that, select the S type instead. The PC bowl is the standard build; the catalogue lists no material-specific ratings, so confirm it suits your environment. The automatic drain is the right call for wet or unattended lines, and the 5 um element trades finer filtration for more frequent service. The PT thread carries a MPa/psi gauge scale; match it to what your operators read. The K code adds the reverse-flow valve, and the two units are orderable separately as GAFR200-08 and GAL200-08. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the regulated range, so set the regulator near its ceiling and let the supply sit comfortably above it.
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 GAFC20008ALWK FAQ
This F.R.L. combination operates on air from 0.15 to 0.4 MPa (20-58 psi) with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C and it must not freeze. The drain bowl holds 25 cc and the oil bowl holds 36 cc, with a recommended lubricant of ISO VG 32. The complete unit weighs 590 g.
The L type code sets the regulated band to 0.15-0.4 MPa (20-58 psi), which suits delicate actuators or processes that must not see higher forces. The W code specifies a 5 um element that traps finer particles than the standard 40 um grade, protecting precision valves but requiring more frequent element service. The automatic drain and reverse-flow valve are separate options that reduce maintenance and alter the pneumatic symbol respectively.
