About the Airtac GAFC Air Service Unit GAFC40010ASNWK
This GAFC40010ASNWK is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a single T-bracket. With a 3/8" port and a 5 um element, it removes fine particles before the regulator sets pressure to 0.15-0.9 MPa (20-130 psi). The automatic drain clears the 100 cc condensate bowl without operator attention, while the 185 cc oil bowl feeds the lubricator.
The reverse-flow valve is fitted, and no gauge is supplied, so the 1/4" gauge connection is available for adding one. Weighing 1810 g, this unit suits a panel or frame mount rather than tubing support. The two-piece design means one less inter-unit joint to seal compared to a three-body train, and the GAFR400-10 filter-regulator and GAL400-10 lubricator are orderable separately.

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 GAFC40010ASNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line, where the 5 um element protects fine internal passages from abrasive particles.
Machine tool lubrication
Supply a metered oil mist to a multi-spindle drilling head, where consistent lubrication extends tool life and the automatic drain handles condensate from a wet compressor line.
Test bench air preparation
Set up a calibration bench with clean, regulated air at 0.15-0.9 MPa (20-130 psi), where the 5 um filtration prevents contamination of sensitive test instruments.
Is the Airtac GAFC Air Service Unit GAFC40010ASNWK the Right Air-Prep Unit?
For a 3/8" line needing fine filtration, this model uses the 5 um element instead of the standard 40 um, trapping finer particles for sensitive valves at the cost of more frequent element service. The automatic drain suits unattended operation, while the PC bowl is the default build choice, and the catalogue specification does not change with bowl material, so confirm compatibility for your surroundings. The PT thread carries a gauge scale of MPa/psi, but since no gauge is fitted, plan to add one at the 1/4" connection to read set pressure. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you need the full output.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC40010ASNWK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and it uses ISO VG 32 lubricant. It has a 100 cc condensate bowl and a 185 cc oil bowl, weighing 1810 g with a 3/8" port.
The N in the code after the port indicates no gauge is supplied. The GAFC400 body has a 1/4" gauge connection, so you can add a gauge later if you need to read the set pressure. The PT thread option would use an MPa/psi scale if a gauge is fitted.
