About the Airtac GAFC Air Service Unit GAFC400C15LWK
This GAFC400C15LWK is an F.R.L. combination where the filter and regulator share one body, and a lubricator is joined on a T bracket with quick clamps. It handles a 1/2in port, regulates from 0.15-0.4 MPa (20-58 psi), and uses a 5 um element to catch fine particles before the air reaches the lubricator.
The metal bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, and the whole unit weighs 1810 g. The circular gauge reads in MPa/psi, and the semi-auto drain plus manual drain are both fitted. A reverse-flow valve is included, and the catalogue shows it as a separate pneumatic symbol.

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 GAFC400C15LWK Is Used
Precision Machining Centers
Feed a 1/2in line to a CNC spindle lubrication system where the lower pressure range protects sensitive metering valves and the 5 um element keeps fine abrasive dust out of the oil mist.
Assembly Line Workstations
Supply a multi-fixture assembly bench that uses pneumatic screwdrivers and small actuators, where the 185 cc oil bowl reduces refill frequency during long production runs.
Packaging Equipment
Power a carton erector's pneumatic cylinders and grippers, where the 100 cc condensate bowl and metal construction handle the occasional washdown without frequent maintenance.
Is the Airtac GAFC Air Service Unit GAFC400C15LWK the Right Air-Prep Unit?
Choose this GAFC400C15LWK when you need a 1/2in port with a lower pressure ceiling of 0.4 MPa (20-58 psi) and a 5 um element for finer filtration. The metal bowl is a build choice, but the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm it suits your environment. The semi-auto drain dumps on pressure drops, while the manual drain works on demand, and the gauge is fitted with an MPa/psi scale for PT threads. If the line must stay oil-free, omit the lubricator and select a plain GAFR400-15 filter-regulator instead; the spares for this unit are GAFR400-15 and GAL400-15. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFC400C15LWK FAQ
The GAFC400C15LWK 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). It works in temperatures from -5 to 70 C and requires ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice, but the catalogue does not provide impact or chemical resistance data, so verify it fits your environment. The L code sets the lower pressure range of 0.15-0.4 MPa, which suits applications that must not exceed this ceiling; if you need more, select the standard S type instead.
