About the Airtac GAFC Air Service Unit GAFC400N15ASW
This AirTAC GAFC400N15ASW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is the second unit on the T-bracket. Air enters the 1/2in port, gets filtered and set to pressure in the first body, then the lubricator adds a controlled oil mist last. It operates from 0.15 to 0.9 MPa (20-130 psi) with a 5 um element, and the nylon bowl holds 100 cc of condensate while the oil bowl holds 185 cc. At 1810 g, it is a substantial unit that needs a proper panel or frame mount rather than support from the tubing.
The automatic drain clears condensate without an operator, which suits lines that run unattended or see wet air. The circular gauge is fitted and reads in MPa and psi for the PT thread. Max pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The temperature range is -5 to 70 C and it must not freeze. The catalogue flow curve for this body is plotted to 6000 L/min at 0.7 MPa inlet, so it can feed a multi-station line or a machine header with several actuators.

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 GAFC400N15ASW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line with the 5 um element filtering out particles that could clog fine orifices, while the regulator holds a stable setpoint for consistent actuation.
Machine tool lubrication
Supply a CNC machine's tool changer or clamping system with filtered, regulated air and a metered oil mist to keep sliding parts and cylinders lubricated during repeated cycles.
Multi-station conveyor
Power a conveyor system with multiple air cylinders at separate stations, using the 1/2in port and 6000 L/min envelope to maintain pressure across the line while the automatic drain handles condensate.
Is the Airtac GAFC Air Service Unit GAFC400N15ASW the Right Air-Prep Unit?
The GAFC400 body with a 1/2in port sits between the GAFC300 (3/8in or 1/2in ports, 1020 g, 3500 L/min envelope) and the GAFC500 (3/4in port, 1910 g, 7000 L/min envelope). Choose the 400 when you need 1/2in connections and more condensate capacity than the 300 offers. The nylon bowl is named here as a build choice, but the shared specification of 1.0 MPa max and -5 to 70 C does not change with material, so confirm it suits your surroundings. The automatic drain is fitted, so no operator needs to empty the bowl manually. The 5 um element traps finer particles than the standard 40 um, which suits precision valves or instrument air, but expect more frequent element service. The PT thread carries a gauge scale in MPa and psi. The two units are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. If the line must stay oil-free, omit the lubricator and choose a plain GAFR instead. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply near 1.0 MPa if you really need 0.9 MPa out.
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 GAFC400N15ASW FAQ
The GAFC400N15ASW operates from 0.15 to 0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 or equivalent lubricant. The element grade is 5 um and the port is 1/2in.
The 5 um element traps particles five times finer than the standard 40 um filter, which is important for precision valves or instrument air where small contaminants can cause issues. The trade-off is that the finer element will load up faster, so you will need to service or replace it more often than a 40 um element.
