About the Airtac GAFC Air Service Unit GAFC400N15ASNK
This GAFC400N15ASNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on the same T-bracket with quick clamps. Air enters the 1/2in port, gets filtered and regulated to 0.15-0.9 MPa (20-130 psi), then oil mist is added downstream. The nylon bowl holds 100 cc of condensate, the oil bowl 185 cc, and the whole unit weighs 1810 g.
The 40 um element handles standard shop air, while the automatic drain clears water without an operator. No gauge is fitted, so the 1/4in gauge connection is available if you add one later. A reverse-flow (reflux) valve is included, and the unit is rated for -5 to 70 C with a 1.0 MPa (145 psi) maximum supply.

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 GAFC400N15ASNK Is Used
Machine tool lubrication
Feed a 1/2in header on a CNC lathe or milling machine, where the 100 cc condensate bowl and 185 cc oil bowl keep the unit running through a shift without frequent attention.
Assembly line stations
Supply a multi-station assembly bench with filtered, regulated air and metered oil mist for pneumatic screwdrivers and fixtures, using the automatic drain to handle condensate from humid shop air.
Packaging equipment
Protect cylinders and valves on a carton erector or strapping machine, where the 1810 g body mounts on a frame and the 6000 L/min flow curve at 0.7 MPa inlet provides sizing headroom for intermittent demand.
Is the Airtac GAFC Air Service Unit GAFC400N15ASNK the Right Air-Prep Unit?
Choose this GAFC400N15ASNK when you need 1/2in ports and a 1810 g body that suits a machine header or a small multi-station line. The nylon bowl is a build choice - the shared specification (1.0 MPa max, -5 to 70 C) does not change with material, so confirm it fits your environment. The automatic drain is ideal for wet or unattended lines, and the 40 um element is the standard grade; step to the W code for 5 um if you feed precision valves. PT threads with an MPa/psi gauge scale are standard, and the K code adds the reverse-flow valve. Spares are orderable as GAFR400-15 and GAL400-15, so a damaged bowl does not force a full replacement. The 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 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 GAFC400N15ASNK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum supply of 1.0 MPa (145 psi) and 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, the oil bowl 185 cc, and the unit weighs 1810 g. Use ISO VG 32 oil in the lubricator.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one. The gauge connection on a GAFC400 is 1/4in, which accepts a standard AirTAC gauge if you need to monitor the regulated output.
