About the Airtac GAFC Air Service Unit GAFC40010SNK
The GAFC40010SNK is an F.R.L. combination where the filter and regulator share one body, and a lubricator is mounted alongside on a T-bracket. With a 3/8in port and 1810 g mass, this size class suits machine headers that feed several actuators from a single prepared air supply.
Air enters the first body where solids and moisture are removed and pressure is set to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist downstream. The 40 um element handles general shop air, while the 100 cc condensate bowl and 185 cc oil bowl define the service interval. No gauge is fitted, so the 1/4in gauge connection is available if you add one later.

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 GAFC40010SNK Is Used
Machine tool lubrication
Feed a 3/8in line to a CNC lathe's tool changer, where filtered air at a set pressure keeps the mechanism moving and the lubricator maintains a fine oil film on sliding surfaces.
Assembly station air prep
Supply a multi-spindle nutrunner on an assembly line, using the 100 cc bowl to catch condensate from a humid plant air system while the regulator holds a stable pressure for consistent torque.
Packaging line actuator bank
Run a bank of pneumatic cylinders on a carton erector, where the 185 cc oil bowl supports extended shifts before needing a refill and the semi-auto drain clears water when the line stops.
Is the Airtac GAFC Air Service Unit GAFC40010SNK the Right Air-Prep Unit?
Choose the GAFC40010SNK when a 3/8in port and 1810 g body provide the right flow envelope for your station. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific ratings. This model carries both a semi-auto drain that dumps on pressure drop and a manual drain for on-demand use. The 40 um element is the default grade, and the reverse-flow (reflux) valve is fitted as an ordering difference. With no gauge supplied, the 1/4in connection lets you add one if operators need to read the setpoint. The PT thread carries an MPa/psi scale on any gauge you fit. For spares, order GAFR400-10 and GAL400-10 separately. Since max supply is 1.0 MPa, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure accordingly.
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 GAFC40010SNK FAQ
This F.R.L. combination operates from 0.15 to 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. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g.
The N in the code after the port means no gauge is supplied with the unit. If you need to read the set pressure, the GAFC400 body provides a 1/4in gauge connection where you can fit a circular gauge with an MPa/psi scale to match the PT thread.
