Airtac GAFC Air Service Unit GAFC20008LWK
The AirTAC GAFC Air Service Unit GAFC20008LWK 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 GAFC20008LWK
This AirTAC GAFC20008LWK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted beside them on a T-bracket. Air enters the 1/4in port, is cleaned by the 5 um element, and regulated down to the 0.15-0.4 MPa (20-58 psi) lower-pressure band before oil mist is metered in downstream.
The PC bowl holds 25 cc of condensate and the oil bowl 36 cc, with the whole assembly weighing 590 g. A circular gauge is fitted with an MPa/psi scale for the PT thread, and the reverse-flow valve is included. The catalogue flow curve is plotted to 1750 L/min at 0.7 MPa inlet, which is a sizing envelope rather than a rated capacity.

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 GAFC20008LWK Is Used
Precision Jig Cylinders
Feed a small clamping cylinder on a CNC fixture with clean, regulated air at a controlled low pressure to avoid damaging delicate workpieces.
Lab Air Bench
Supply a laboratory pneumatic test rig where fine 5 um filtration protects miniature valves and the lower pressure range suits sensitive experiments.
Semi-Auto Assembly Tool
Power a handheld screwdriver or small press on an assembly bench, with oil mist keeping the tool lubricated and a soft pressure limit for consistent torque.
Is the Airtac GAFC Air Service Unit GAFC20008LWK the Right Air-Prep Unit?
Choose this GAFC20008LWK when your circuit needs fine filtration and a soft pressure ceiling. The 5 um element traps particles that would pass a standard 40 um filter, making it suitable for small precision actuators or sensitive pilot valves. The lower-pressure type tops out at 0.4 MPa, so if the machine may ever require more than that, select the standard 0.15-0.9 MPa version instead.
The semi-auto drain dumps condensate when pressure drops, with a manual override for on-demand purging. The PC bowl is the standard build; confirm it suits your environment since the catalogue lists no material-specific ratings. Spares are the GAFR200-08 filter-regulator and GAL200-08 lubricator, both orderable separately. With a 1.0 MPa max supply, there is about 0.6 MPa of headroom above this unit's 0.4 MPa regulated top.
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 GAFC20008LWK FAQ
The GAFC20008LWK operates 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). It is rated for -5 to 70 C and must not freeze. The drain bowl holds 25 cc and the oil bowl 36 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 590 g.
The K indicates a reverse-flow (reflux) valve is fitted to this GAFC20008LWK. The catalogue shows it as a separate pneumatic symbol on the unit. It is an ordering difference to note; the standard GAFC20008LW without the K does not include this valve.
