About the Airtac GAFC Air Service Unit GAFC40015LWK
This AirTAC GAFC40015LWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/2in port and 1810 g mass place it in the mid-range GAFC400 class, sized for a machine header feeding several actuators rather than a single small cylinder.
Air enters the first body where the 5 um element traps fine particles and the lower-pressure regulator sets the output between 0.15-0.4 MPa (20-58 psi). The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never travels back through the regulator seat. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, and the circular gauge reads in MPa/psi for the PT thread.

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 GAFC40015LWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a CNC machining center where the 5 um element protects fine internal passages and the lower pressure range suits delicate actuation.
Assembly line tooling
Supply a multi-station assembly fixture with filtered, regulated, lubricated air at a consistent lower pressure, reducing wear on slides and grippers that cycle continuously.
Packaging machine header
Run a packaging machine's main air header at 0.15-0.4 MPa for film handling and sealing actuators, with the 185 cc oil bowl supporting longer runs between refills.
Is the Airtac GAFC Air Service Unit GAFC40015LWK the Right Air-Prep Unit?
The GAFC400 body suits a 1/2in port line where the GAFC300's 3500 L/min envelope at 0.7 MPa inlet is too small, while the GAFC500's 7000 L/min envelope at 0.7 MPa inlet would be oversizing. The L pressure type tops out at 0.4 MPa, so if the machine may ever need more than that, step up to the standard S type instead. The PC bowl is the default build; confirm it suits your environment since the catalogue gives no material-specific ratings. Both the semi-auto drain (dumps on pressure drop) and manual drain (on demand) are fitted. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. The circular gauge is fitted and reads MPa/psi for the PT thread. The reverse-flow (reflux) valve is fitted as an ordering difference. Spares are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure with that margin in mind.
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 GAFC40015LWK FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 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. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1810 g.
The L code sets the regulated output to 0.15-0.4 MPa, which suits applications needing gentle, consistent actuation rather than full line pressure. The W code specifies a 5 um element that traps finer particles than the standard 40 um, protecting precision valves and instruments. The trade-off is more frequent element service compared to a coarser filter.
