About the Airtac GAFC Air Service Unit GAFC40015SNWK
The GAFC40015SNWK is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is mounted after it on a T-bracket with quick clamps. Air is cleaned and set to pressure in the first unit, then a metered oil mist is added downstream, so the oil never travels back through the regulator seat. This 1/2in port model carries a 5 um element and operates from 0.15 to 0.9 MPa (20-130 psi).
With a 1810 g mass and a 100 cc condensate bowl plus a 185 cc oil bowl, this size class suits a machine header or a multi-station line rather than a single small actuator. The PC bowl is the standard build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. No gauge is supplied, but the 1/4in gauge connection is ready for one if you need to read the set pressure.

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 GAFC40015SNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line, where the 5 um element keeps fine particles from affecting spool movement and the regulated air holds a stable setpoint.
Machine tool lubrication
Supply a multi-station machining center's air header, where the 185 cc oil bowl supports consistent mist delivery to several actuators and the 100 cc drain bowl extends time between condensate checks.
Instrument air for test rigs
Run a laboratory test bench with air cylinders and sensors, relying on the 5 um filtration and the reverse-flow valve to keep the regulated pressure stable when the downstream load changes.
Is the Airtac GAFC Air Service Unit GAFC40015SNWK the Right Air-Prep Unit?
Choose the GAFC40015SNWK when a 1/2in port and a 5 um element are needed for finer filtration, such as feeding precision valves or instrument air. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. The reverse-flow (reflux) valve is fitted, and the catalogue shows it as a separate pneumatic symbol. The PT thread carries a gauge scale in MPa/psi if a gauge is added later. For a smaller footprint, step down to the GAFC300 with its 3500 L/min envelope at 0.7 MPa inlet; for more capacity, step up to the GAFC500 with a 3/4in port and a 7000 L/min envelope. Spares are orderable as GAFR400-15 and GAL400-15. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan the supply pressure near 1.0 MPa if you need the full regulated output.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC40015SNWK FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi), with a max 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 100 cc and the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1810 g.
The N after the port code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. The PT thread would use a gauge scale in MPa/psi.
