About the Airtac GAFC Air Service Unit GAFC20008ASW
This AirTAC GAFC20008ASW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted beside it on a T-bracket with quick clamps. Air is cleaned and set to pressure in the first unit, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat. With a 1/4in port and a 590 g mass, it suits compact machines where a full three-body train would be overkill.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 5 um element traps fine particles for sensitive valves. The automatic drain clears condensate from the 25 cc bowl without an operator, while the 36 cc oil bowl feeds the lubricator. A circular gauge is fitted, reading MPa and psi on the PT thread scale.

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 GAFC20008ASW Is Used
Precision Fixture Clamping
Feed a small pneumatic vise or indexing fixture on a benchtop assembly station, where the 5 um element protects fine metering valves from particle wear.
Single-Axis Slide Tables
Power a compact rodless slide or pick-and-place arm on a packaging line, using the automatic drain to keep condensate out of the cylinder during long shifts.
Lab Air Supply
Supply filtered, regulated air to a small test rig or calibration bench, where the 0.15-0.9 MPa range covers typical instrument air setpoints.
Is the Airtac GAFC Air Service Unit GAFC20008ASW the Right Air-Prep Unit?
Choose the GAFC200 body for small actuators, jigs, or single-station tooling where the 1/4in port matches your tubing. The 5 um element (W) gives finer filtration than the standard 40 um, at the cost of more frequent element service. The automatic drain (A) is the right call for unattended lines, as it purges water without manual intervention. The PC bowl is the default build; confirm it suits your environment, as the catalogue gives no material-specific ratings. The PT thread carries a gauge scale in MPa/psi, so operators read the same units as your other local gauges.
The filter-regulator and lubricator are orderable separately as GAFR200-08 and GAL200-08, so a damaged bowl or clogged element does not force a full replacement. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan your inlet pressure near the maximum if you need the full output.
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 GAFC20008ASW FAQ
The GAFC20008ASW operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum 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 lubricant. The drain bowl holds 25 cc, the oil bowl holds 36 cc, and the complete unit weighs 590 g.
The W code specifies a 5 um element, which traps significantly finer particles than the standard 40 um grade. This is suited for precision pneumatic valves, instrument air, or applications where small contaminants could cause sticking or wear. The trade-off is that the finer element loads faster and will need more frequent servicing or replacement.
