About the Airtac GAFC Air Service Unit GAFC400N15ASNW
This AirTAC GAFC400N15ASNW is a two-piece F.R.L. combination: the first body houses both the filter and the regulator, and the second body is the lubricator that adds a metered oil mist last, downstream of the pressure setpoint. With a 1/2in port and a 1810 g mass, it suits medium-size machine headers or multi-actuator stations where a single air prep point feeds several valves.
The nylon bowl holds 100 cc of condensate and the oil bowl holds 185 cc, so the service interval is driven by how often you attend the unit rather than by line pressure alone. It regulates from 0.15 to 0.9 MPa (20-130 psi) and filters to 5 um, trapping finer particles for downstream precision valves. No gauge is supplied; the 1/4in gauge connection is ready if you add one.

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 GAFC400N15ASNW Is Used
CNC coolant valves
Feed a bank of solenoid valves on a CNC machine tool where 5 um filtration protects fine orifices and the automatic drain keeps condensate out of the coolant system.
Assembly line headers
Supply a 1/2in header on a multi-station assembly line, giving each station filtered, regulated air with oil mist for pneumatic screwdrivers and actuators.
Packaging machine air prep
Prepare air for a packaging machine's film-seal cylinders and grippers, where the 185 cc oil bowl supports continuous cycling without frequent refills.
Is the Airtac GAFC Air Service Unit GAFC400N15ASNW the Right Air-Prep Unit?
Choose the GAFC400 body when your line needs 1/2in ports and a 6000 L/min flow envelope at 0.7 MPa inlet, which is nearly double the GAFC300's 3500 L/min curve for the same inlet condition. The nylon bowl is a build choice, not a performance upgrade, and the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm nylon suits your environment. The automatic drain clears condensate without an operator, ideal for unattended runs, while the 5 um element catches finer particles than the standard 40 um but will need more frequent service. The PT thread carries a dual MPa-psi gauge scale if you fit a gauge later, and the GAFR400-15 filter-regulator and GAL400-15 lubricator are orderable separately. A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure with that narrow headroom 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 GAFC400N15ASNW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g with a 1/2in port.
The N after the port code means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. The PT thread option uses a dual MPa-psi scale when a gauge is fitted.
