Airtac GAFC Air Service Unit GAFC40015LNWK
The AirTAC Airtac GAFC Air Service Unit GAFC40015LNWK is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015LNWK
This F.R.L. combination pairs a filter-regulator body with a lubricator on a shared T-bracket, so the air is cleaned, set to pressure, then given a metered oil mist in the final stage. The 1/2in port and 1810 g mass place it in the mid-size GAFC400 class, suited to a machine header feeding several actuators.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), which suits delicate circuits but not plant lines that may need more. A 5 um element traps fine particles for sensitive valves, and the 100 cc condensate bowl plus 185 cc oil bowl set the service rhythm. No gauge is supplied, so the 1/4in gauge connection is left for the installer to fit.

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 GAFC40015LNWK Is Used
Precision assembly fixtures
Feed a 1/2in line to a pneumatic press or assembly jig where the lower 0.4 MPa range protects delicate clamping forces and the 5 um element keeps fine particles off precision valve seats.
Machine tool lubrication
Supply a small machining center's way-lubrication system with filtered, regulated air and a controlled oil mist, using the 185 cc oil bowl to maintain consistent lubrication over a shift.
Test bench air supply
Run a laboratory test bench or calibration rig at pressures below 0.4 MPa, where the fine 5 um filtration protects sensitive instrumentation and the semi-auto drain keeps the condensate bowl clear.
Is the Airtac GAFC Air Service Unit GAFC40015LNWK the Right Air-Prep Unit?
Choose the GAFC40015LNWK when the line stays below 0.4 MPa and a fine 5 um element is preferred for precision equipment. The PC bowl is the standard build, and the semi-auto drain dumps condensate on pressure drops while the manual drain gives on-demand control. The reverse-flow valve is fitted, and the PT thread carries a gauge scale in MPa/psi if a gauge is added later. Spares are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. Since the lubricator adds oil mist, select a plain GAFR filter-regulator instead if the downstream air must stay oil-free. With a 1.0 MPa max supply, the unit has about 0.6 MPa of headroom above its 0.4 MPa regulated ceiling.
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 GAFC40015LNWK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc condensate bowl and a 185 cc oil bowl, weighs 1810 g, and uses a 5 um filter element.
The N in the code means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so a standard 1/4in pressure gauge can be added later if the operator needs to read the set pressure directly. The PT thread option means any gauge fitted should have an MPa/psi scale.
