About the Airtac GAFC Air Service Unit GAFC40015ASNW
This GAFC40015ASNW 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 put it in the mid-size class, a step up from the GAFC300's 1020 g for lines that need more condensate and oil capacity. Air is filtered and regulated in the first body, then the lubricator adds a controlled oil mist last, so oil never passes back through the regulator seat.
The 5 um element traps finer particles than the standard 40 um grade, suiting precision valves or instrument air. The automatic drain clears condensate without an operator, and the 100 cc drain bowl plus 185 cc oil bowl set the service interval. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/4in gauge connection. The working range is 0.15-0.9 MPa (20-130 psi), with max pressure 1.0 MPa (145 psi) and proof pressure 1.5 MPa (215 psi).

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 GAFC40015ASNW Is Used
CNC Coolant Lines
Feed a 1/2in header on a CNC machine, where the 5 um element protects fine coolant valves and the automatic drain handles condensate from a wet compressor.
Assembly Station Air
Supply a multi-station assembly bench with filtered, regulated, oil-misted air for pneumatic screwdrivers and small cylinders, with the 185 cc oil bowl lasting a full shift.
Packaging Line Actuators
Run a bank of packaging line actuators at a set 0.6 MPa, relying on the 100 cc drain bowl to collect moisture between weekly maintenance rounds.
Is the Airtac GAFC Air Service Unit GAFC40015ASNW the Right Air-Prep Unit?
Choose the GAFC400 body when a 1/2in port and 1810 g mass fit your panel layout, and the 100 cc condensate bowl plus 185 cc oil bowl reduce how often someone checks the unit. The PC bowl is the standard build; the catalogue lists metal and nylon as alternatives, but confirms the material suits your surroundings before ordering. The automatic drain (A) is the right call for unattended or wet lines, while the blank drain option ships both semi-auto and manual drains. The 5 um element (W) filters finer than the 40 um standard but needs more frequent service. With no gauge (N), the 1/4in connection is ready for one later. PT thread is the default, with a gauge scale in MPa/psi. The two units are orderable separately as GAFR400-15 and GAL400-15. If the line must stay oil-free, leave the lubricator out and choose a plain filter-regulator instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near 1.0 MPa if you need the full output.
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 GAFC40015ASNW FAQ
This F.R.L. combination works with air, filtering to 5 um. The standard pressure range is 0.15-0.9 MPa (20-130 psi). Max pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The N in the code after the port means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add one later if you need to read the set pressure. The PT thread version uses a gauge scale in MPa/psi.
