About the Airtac GAFC Air Service Unit GAFC400N15AS
This GAFC400N15AS is an F.R.L. combination where the filter and regulator share one body, paired with a lubricator on a T-bracket. With a 1/2in port and 1810 g mass, it suits mid-size machine headers or multi-actuator stations where a compact footprint matters. The nylon bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, reducing how often an operator needs to check levels.
Air enters the first body, where solids and moisture are removed and pressure is set to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist downstream. The automatic drain clears condensate without manual intervention, and the circular gauge reads in MPa/psi for the default PT thread. The 40 um element handles standard shop air, with the option to step down to 5 um for finer filtration.

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 GAFC400N15AS Is Used
CNC Coolant Systems
Feed a 1/2in line to a CNC machine's coolant valve manifold. The 100 cc condensate bowl handles moisture from compressor cycling, while the automatic drain keeps the line clear during overnight runs.
Assembly Station Headers
Supply a multi-operator assembly station where each bench has a pneumatic screwdriver. The 185 cc oil bowl ensures consistent lubrication across several tools before needing a refill.
Packaging Line Actuators
Run a packaging machine's film-sealing cylinders from a single F.R.L. point. The 1810 g unit mounts on a frame rail, and the 0.15-0.9 MPa range covers typical cylinder thrust settings.
Is the Airtac GAFC Air Service Unit GAFC400N15AS the Right Air-Prep Unit?
Choose this GAFC400N15AS for a 1/2in port line needing filtration, regulation, and lubrication in two units instead of three. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C range stay the same, so confirm it suits your environment. The automatic drain (A) is ideal for wet or unattended lines, while the standard type (S) covers most industrial duties up to 0.9 MPa. The gauge is fitted and reads MPa/psi; if you prefer no gauge, the N option removes it. Spares are orderable as GAFR400-15 and GAL400-15, so a damaged bowl or clogged element does not mean replacing the whole set. If your line must stay oil-free, skip the lubricator and choose a plain GAFR400-15 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 your 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 GAFC400N15AS FAQ
The GAFC400N15AS operates on air only, with a standard pressure range of 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi), and proof pressure is 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and must not freeze. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g. Use ISO VG 32 or equivalent lubricant in the lubricator.
The 'A' in this code specifies an automatic drain, which clears condensate from the 100 cc bowl without an operator. A blank drain code would include both a semi-auto drain that dumps on pressure drop and a manual drain for on-demand use. The automatic version is better for lines that run unattended or in wet conditions.
