About the Airtac GAFC Air Service Unit GAFC20006ALK
This GAFC20006ALK is a two-piece F.R.L. combination: a filter-regulator body that cleans the air and sets its pressure, followed by a lubricator that adds a metered oil mist. The 1/8in port and 590 g mass suit a compact machine frame, and the automatic drain clears the 25 cc condensate bowl without an operator.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), so this unit is for gentle duties, not high-force actuators. The 40 um element handles standard shop air, while the 36 cc oil bowl keeps the lubricator running between refills. A circular gauge with an MPa/psi scale is fitted, and the reverse-flow valve is included in this build.

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 GAFC20006ALK Is Used
Low-Pressure Jigs
Feed a small clamping jig on a benchtop assembly station where the actuator only needs gentle force and the automatic drain keeps the bowl from flooding during light use.
Lab Air Lines
Supply a laboratory test rig that uses a low-pressure air pulse, where the 0.15-0.4 MPa range matches the experiment's needs and the 40 um filter protects a sensitive valve.
Compact Paint Spray
Run a small touch-up spray gun that operates below 0.4 MPa, with the lubricator adding a fine oil mist to the air tool and the 1/8in port fitting a tight hose run.
Is the Airtac GAFC Air Service Unit GAFC20006ALK the Right Air-Prep Unit?
Choose this GAFC20006ALK when your line runs at low pressure and needs an automatic drain. The L type caps at 0.4 MPa, so if the machine may ever need more, select the S type instead. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific ratings. The 40 um element is the default, and the PT thread carries an MPa/psi gauge scale. The reverse-flow valve is fitted, and the two units are orderable separately as GAFR200-06 and GAL200-06. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (1/8" 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 GAFR200-06 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC20006ALK FAQ
This lower-pressure unit works from 0.15 to 0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, uses ISO VG 32 oil, has a 25 cc drain bowl and a 36 cc oil bowl, and weighs 590 g.
The L code specifies a regulator that tops out at 0.4 MPa instead of the standard 0.9 MPa. This suits delicate processes that must not see higher pressure, but it means the unit cannot drive high-force cylinders. The 1.0 MPa max supply still applies, so the regulator has a 0.6 MPa buffer above its setpoint.
