About the Airtac GAFC Air Service Unit GAFC300N15ASWK
This GAFC300N15ASWK is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is joined to it on a T bracket with quick clamps. Air is cleaned and set to pressure in the first body, then the lubricator adds a controlled oil mist last, so oil never travels back through the regulator seat. With a 1/2in port and 1020 g mass, it suits a mid-size machine header or a multi-actuator station where a smaller 1/4in unit would restrict the air supply.
The working range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. This model carries the 5 um element for finer filtration, a nylon bowl, and an automatic drain that clears condensate without an operator. The 60 cc drain bowl and 98 cc oil bowl set the service rhythm, and the unit is rated for -5 to 70 C and must not freeze.

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 GAFC300N15ASWK Is Used
Machine Tool Lubrication
Feed a 1/2in line to a CNC lathe's tool changer and tailstock cylinders, where the 5 um element protects precision valves and the automatic drain handles condensate from a wet shop line.
Assembly Station Air Prep
Supply a multi-operator assembly bench with filtered, regulated, and lubricated air for pneumatic screwdrivers and push-in fittings, where the 60 cc drain bowl and 98 cc oil bowl reduce daily checks.
Packaging Line Actuators
Run a section of a packaging conveyor with several 1/2in ported cylinders, relying on the automatic drain to keep a continuous operation free of water buildup in the condensate bowl.
Is the Airtac GAFC Air Service Unit GAFC300N15ASWK the Right Air-Prep Unit?
The GAFC300 body with a 1/2in port sits between the 3/8in GAFC300 and the 3/4in GAFC500 in port size, but its 1020 g weight and 60 cc drain bowl are the same class as other GAFC300 models. The nylon bowl is a material choice only; the 1.0 MPa maximum and -5 to 70 C rating do not change with bowl material, so confirm it suits your environment. The automatic drain is for unattended lines, while the 5 um element traps finer particles than the standard 40 um but will need more frequent service. A circular gauge is fitted, reading MPa and psi on the PT thread scale. The reverse-flow (reflux) valve is fitted, and the catalogue draws it as a separate pneumatic symbol. The two units are orderable separately as GAFR300-15 and GAL300-15. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa if you need the full regulated 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N15ASWK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc and the oil bowl holds 98 cc, with a total weight of 1020 g. The element grade is 5 um.
The N before the port code specifies a nylon bowl, which is a build choice for the environment; the catalogue does not publish impact or chemical data for it, so confirm compatibility. The A after the port specifies an automatic drain, which clears condensate without an operator, making it suitable for unattended or wet air lines.
