About the Airtac GAFC Air Service Unit GAFC40015ASNWK
This GAFC40015ASNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a T-bracket with quick clamps. Air enters the 1/2in port, gets filtered to 5 um and regulated to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist downstream. The 1810 g unit needs a proper panel or frame mount, not support from the tubing.
The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the automatic drain clears water without an operator. No gauge is supplied, so the 1/4in gauge connection is where one would be added. The reverse-flow (reflux) valve is fitted, and the PT thread carries a MPa/psi scale if a gauge is installed later. The 5 um element traps finer particles than the standard 40 um, which suits precision valves but requires more frequent element service.

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 GAFC40015ASNWK Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves on a CNC machine tool from fine particles that would otherwise cause sticking or premature wear.
Assembly line stations
A 1/2in port and 1810 g build suit a multi-station assembly line where each station needs filtered, regulated, lubricated air for actuators and grippers.
Paint spray booth
The automatic drain keeps condensate out of a paint spray booth's air supply, while the 5 um element removes particles that could mar a finish.
Is the Airtac GAFC Air Service Unit GAFC40015ASNWK the Right Air-Prep Unit?
Choose this GAFC400 if your line needs 1/2in ports and the 1810 g mass tells you it is a mid-size unit. The PC bowl is the default build, and the automatic drain makes it suited for unattended operation. The 5 um element is the finer filtration option, while the standard 40 um is the default. The L type (0.15-0.4 MPa) is available on this body if you need a lower regulated band. The no-gauge code means the 1/4in connection is ready for a field-installed gauge, and the PT thread uses a MPa/psi scale. The reverse-flow valve is fitted per the K code. Spare parts are orderable as GAFR400-15 and GAL400-15. If the line must stay oil-free, 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 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 GAFC40015ASNWK FAQ
The working pressure range is 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). Operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g. The 5 um element filters the air, and the automatic drain clears condensate without an operator.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC400 body is 1/4in, so you can add a field-installed gauge there if you need to read the set pressure. The PT thread uses a MPa/psi scale on any compatible gauge.
