Airtac GAFC Air Service Unit GAFC30008ALNWK
The AirTAC Airtac GAFC Air Service Unit GAFC30008ALNWK 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 GAFC30008ALNWK
This AirTAC GAFC30008ALNWK is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a T bracket. The 1/4in port and 1020 g mass place it in the mid-size class, suited for a single machine station or a small assembly bench. It operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi), with a 5 um element that traps finer particles for sensitive valves. The automatic drain clears condensate from the 60 cc bowl without an operator, and the 98 cc oil bowl holds enough lubricant for extended runs. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in connection.
The reverse-flow (reflux) valve is fitted, and the catalogue draws it as a separate pneumatic symbol. Air is filtered and regulated in the first body, then the lubricator adds a metered oil mist last, so oil never passes back through the regulator seat. The 5 um element means more frequent service than a 40 um grade, a trade-off for finer filtration. Spare parts are orderable separately as the GAFR300-08 filter & regulator and the GAL300-08 lubricator, so a clogged element does not force a full replacement.

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 GAFC30008ALNWK Is Used
Precision valve control
Feed a precision pneumatic valve on a small assembly fixture with 5 um filtered air, regulated down to 0.4 MPa for gentle actuation.
Test bench air supply
Supply a lab test bench with clean, lubricated air at a stable lower pressure for repeated cycle testing of small cylinders.
Single station lubrication
Lubricate a single pick-and-place station on a packaging line, with the automatic drain handling condensate from wet compressor lines.
Is the Airtac GAFC Air Service Unit GAFC30008ALNWK the Right Air-Prep Unit?
Choose this GAFC30008ALNWK when your line needs lower regulated pressure up to 0.4 MPa and fine 5 um filtration. The automatic drain suits unattended operation, while the PC bowl is a build choice - confirm it fits your surroundings, as the catalogue gives no material-specific data. The 1/4in port feeds a single actuator or small jig; step up to the GAFC400 with a 3/8in port and 100 cc drain bowl if you need more condensate capacity. The no-gauge version leaves the 1/8in connection open for your own gauge if you add one later. For oil-free air, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC30008ALNWK FAQ
This lower-pressure unit operates at 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied, leaving a 1/8in connection if you want to add one. The K code means a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. This unit also has a 5 um element and an automatic drain.
