Airtac GAFC Air Service Unit GAFC40015LK
The AirTAC Airtac GAFC Air Service Unit GAFC40015LK 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 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015LK
This GAFC40015LK is an F.R.L. combination built as two units on a T-bracket: a filter-regulator body handling filtration and pressure control, then a lubricator adding oil mist downstream. The 1/2in port and 1810 g mass place it in the mid-size class, suited for machine headers feeding several actuators. It operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi), with a 40 um element and a circular gauge reading MPa/psi.
The filter and regulator share one body, so the assembly has one less inter-unit joint than a three-piece train. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm: the oil reservoir needs attention roughly twice as often as the water trap. A reverse-flow (reflux) valve is fitted, and the semi-auto drain dumps condensate each time pressure drops, with a manual override for on-demand emptying.

Where the Airtac GAFC Air Service Unit GAFC40015LK Is Used
Precision Fixture Clamping
Feed a multi-point clamping fixture on a CNC machine where consistent 0.3 MPa clamping force holds thin-walled parts without distortion.
Assembly Line Pick-and-Place
Supply a pick-and-place arm on an electronics assembly line, where the lower pressure range prevents damage to delicate components during placement.
Film Sealing Station
Run a heat-sealing press on a packaging line, using the regulated 0.35 MPa output to control sealing pressure on variable product heights.
Is the Airtac GAFC Air Service Unit GAFC40015LK the Right Air-Prep Unit?
Choose the GAFC40015LK when your circuit runs below 0.4 MPa and you need a 1/2in port. The L type caps at 0.4 MPa, so if the machine may ever require more pressure, step to the standard S type instead. The PC bowl is the default build; confirm it suits your environment, as the catalogue gives no material-specific chemical or impact data. The semi-auto drain suits attended lines where operators can check the bowl, while the fitted gauge shows the setpoint on an MPa/psi scale for the PT thread. The 5 um element option (W) would trap finer particles but needs more frequent service. Spares are orderable as GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your 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 GAFC40015LK FAQ
This F.R.L. combination works with air, filtering to 40 um and regulating from 0.15-0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. 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 specifies a lower-pressure regulator, topping out at 0.4 MPa instead of 0.9 MPa. This suits applications needing gentle, precise pressure control, such as delicate clamping or soft-touch assembly. The trade-off is that it cannot supply higher pressures if your process changes, so verify your maximum requirement before selecting this variant.
