About the Airtac GAFC Air Service Unit GAFC400N15LNWK
This GAFC400N15LNWK 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-size class, suitable for feeding a multi-station machine header rather than a single small actuator.
Air enters the first body where the 5 um element removes fine particles and the regulator sets pressure within the lower 0.15-0.4 MPa (20-58 psi) band. The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never travels back through the regulator seat. The nylon bowls hold 100 cc for condensate and 185 cc for oil, and the semi-auto drain dumps water each time pressure drops while the manual drain offers on-demand release.

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 GAFC400N15LNWK Is Used
Precision Assembly Stations
Feed a 5 um-filtered, 0.4 MPa-regulated air supply to pneumatic torque tools on an electronics assembly line, where fine particles could damage precision mechanisms.
Paint Spray Booth Controls
Supply a lower-pressure 0.15-0.4 MPa output to atomizing spray valves in a finishing booth, with the 185 cc oil bowl supporting continuous lubricator operation.
Laboratory Test Rigs
Power pneumatic actuators in a materials testing frame that requires a stable 0.4 MPa maximum, using the 5 um element to protect sensitive flow control orifices.
Is the Airtac GAFC Air Service Unit GAFC400N15LNWK the Right Air-Prep Unit?
Choose this GAFC400N15LNWK when your line needs fine 5 um filtration and a regulated 0.15-0.4 MPa (20-58 psi) output, but be certain the application never requires more than 0.4 MPa - the L type tops out there, and exceeding it calls for a standard S model. The nylon bowl is a build choice; the catalogue gives no material-specific ratings, so confirm it suits your environment. No gauge is fitted, but the 1/4in gauge connection allows adding one later. The reverse-flow (reflux) valve is included, and the PT thread carries an MPa/psi scale if a gauge is installed. The semi-auto plus manual drain pair handles condensate without power. For oil-free lines, omit the lubricator and select a plain GAFR400-15 filter-regulator instead; the lubricator section is orderable separately as GAL400-15. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan 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 GAFC400N15LNWK FAQ
This F.R.L. combination operates on air at 0.15-0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and it must not freeze. It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and the recommended lubricant is ISO VG 32 or equivalent.
The N after the port code means no pressure gauge is supplied, though the 1/4in gauge connection allows adding one. The K code indicates the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. The L code sets the lower 0.15-0.4 MPa pressure range, and W specifies the 5 um filter element.
