About the Airtac GAFC Air Service Unit GAFC40015ASNK
This GAFC40015ASNK is an F.R.L. combination built from two units on a T-shape bracket: a GAFR filter-regulator (filter and regulator share one body) plus a GAL lubricator. Air is filtered and pressure-set in the first body, then the lubricator adds a controlled oil mist last, downstream of the regulator. With a 1/2in port and 1810 g mass, this size class suits mid-size machine headers or multi-actuator stations, and needs a proper panel or frame mount rather than tubing support.
The working range is 0.15-0.9 MPa (20-130 psi), with a 40 um element and an automatic drain that clears condensate without an operator. The 100 cc condensate bowl and 185 cc oil bowl define the service interval: the larger capacity means fewer interventions compared to a GAFC200's 25 cc drain bowl. A reverse-flow (reflux) valve is fitted, and no gauge is supplied, so the gauge connection is 1/4in if one is added 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 GAFC40015ASNK Is Used
CNC coolant valve control
Feed a 1/2in header supplying solenoid valves on a CNC lathe's coolant system, where the automatic drain keeps condensate out of the valve bank during long unmanned shifts.
Assembly line pick-and-place
Power a multi-station pick-and-place unit on an assembly line, with the 185 cc oil bowl keeping gripper cylinders lubricated across a full shift without frequent topping up.
Packaging machine air prep
Condition air for a carton erector's pneumatic cylinders and sensors, where the 100 cc drain bowl and automatic drain reduce maintenance stops in a dusty packaging hall.
Is the Airtac GAFC Air Service Unit GAFC40015ASNK the Right Air-Prep Unit?
Choose the GAFC400 for a 1/2in port with a flow envelope plotted to 6000 L/min at 0.7 MPa inlet, stepping up from the GAFC300's 3500 L/min curve. The bowl is PC (blank code), which shares the same 1.0 MPa max and -5 to 70 C rating as metal or nylon options; confirm the material suits your surroundings. The automatic drain (A) is ideal for unattended lines, while the standard type (S) regulates 0.15-0.9 MPa (20-130 psi). No gauge is fitted (N), so plan to add one at the 1/4in connection if operators need to read set pressure. The PT thread carries an MPa/psi scale, and the 40 um element handles general shop air. The reverse-flow (reflux) valve is fitted per the K code. 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 inlet 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 GAFC40015ASNK FAQ
The GAFC40015ASNK operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl and 185 cc oil bowl, weighs 1810 g, and uses a 40 um element. The port is 1/2in with PT thread, and the automatic drain clears condensate without operator intervention.
The N in the code after the port means no gauge is supplied with the GAFC40015ASNK. The gauge connection is 1/4in, so you can add a circular gauge later if operators need to read the set pressure. The PT thread determines the gauge scale, which would be MPa/psi if a gauge is fitted.
