About the Airtac GAFC Air Service Unit GAFC20008ALK
This GAFC20008ALK is a compact F.R.L. combination for a 1/4in air line, rated for lower-pressure duty from 0.15 to 0.4 MPa (20-58 psi). The filter and regulator share one body, so the set is two pieces on a T bracket, with the lubricator adding a metered oil mist after the pressure is set. It includes a 40 um element and a circular gauge reading MPa/psi.
The 25 cc condensate bowl and 36 cc oil bowl set the service rhythm for a 590 g unit, and the automatic drain clears water without an operator. A reverse-flow valve is fitted, and the catalogue flow curve for this body is plotted to 1750 L/min at 0.7 MPa inlet. With a 1.0 MPa maximum supply, there is about 0.6 MPa of headroom above the 0.4 MPa regulated ceiling.

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 GAFC20008ALK Is Used
Precision pressure for small jigs
Feed a single-acting clamp or a small positioning jig with a stable 0.15-0.4 MPa supply, keeping delicate workpieces from being over-pushed.
Lab air for sensitive instruments
Supply a low-pressure air knife or a lab test fixture where the 0.4 MPa ceiling prevents accidental over-pressure to fragile components.
Light packaging line lubrication
Lubricate a small cylinder on a carton sealer or a bottle capper, with the automatic drain handling condensate from a humid plant line.
Is the Airtac GAFC Air Service Unit GAFC20008ALK the Right Air-Prep Unit?
Choose this GAFC20008ALK when your machine needs a 1/4in port and a regulated output capped at 0.4 MPa (20-58 psi) - the L type suits gentle actuators or precision blow-off stations, not lines that may later demand more pressure. The PC bowl is the standard build, and the automatic drain suits unattended operation; the 40 um element handles general shop air. The PT thread carries a gauge scaled in MPa/psi, and the K code adds the reverse-flow valve as an ordering difference. If the line must stay oil-free, omit the lubricator and select a plain GAFR filter-regulator instead; otherwise, spares are the GAFR200-08 and GAL200-08. With 1.0 MPa max supply, the regulated band tops out at 0.4 MPa, so you have about 0.6 MPa of supply headroom above the setpoint.
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 GAFC20008ALK FAQ
It is a lower-pressure F.R.L. combination with a 1/4in port, working range 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. The drain bowl holds 25 cc, the oil bowl 36 cc, and the unit weighs 590 g. Use ISO VG 32 oil in the lubricator.
The L code sets the regulated output to 0.15-0.4 MPa instead of the standard 0.15-0.9 MPa. This suits applications that must never see high pressure, such as fine blow-off or light clamping. If your machine may need more than 0.4 MPa later, the L type is the wrong part - choose the S type instead.
