About the Airtac GAFC Air Service Unit GAFC300N15SNK
This AirTAC GAFC300N15SNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is a separate unit joined on a T-bracket with quick clamps. Air is cleaned and set to pressure in the first body, then a metered oil mist is added downstream, so oil never crosses the regulator seat. The 1/2in port and 1020 g mass place it in the mid-size class, needing a proper panel mount rather than tubing support.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, which sets the service rhythm for this unit. The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element and no gauge supplied (the 1/8in gauge connection is there if one is added later). A reverse-flow valve is fitted, shown as a separate symbol in the catalogue. The semi-auto drain dumps on pressure drop, with a manual override for on-demand emptying.

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 GAFC300N15SNK Is Used
Precision jig clamping
Feed a single-station clamping fixture on a CNC mill where the 1/2in port delivers enough air for a pair of cylinders, and the 40 um element protects the valve spools from fine shop dust.
Conveyor stop gates
Run the stop-gate cylinders on a light assembly conveyor with this unit, using the semi-auto drain to clear condensate on each line shutdown and the manual drain for scheduled maintenance.
Carton erector feed
Supply a carton-erecting machine's folding and sealing actuators, where the 98 cc oil bowl keeps the mist topped up through a full shift and the nylon bowl suits a dry, indoor environment.
Is the Airtac GAFC Air Service Unit GAFC300N15SNK the Right Air-Prep Unit?
Choose this GAFC300N15SNK when a 1/2in port suits your line and you want the nylon bowl option, which is a build choice - the 1.0 MPa max and -5 to 70 C rating are identical across PC, metal and nylon, so confirm the material fits your surroundings. The semi-auto plus manual drain pair works for attended stations; step to the A code for automatic draining. The 40 um element is the standard grade, and the PT thread carries a MPa/psi gauge scale if you add a gauge later. The reverse-flow valve is fitted per the K code, and the two units are separately orderable as GAFR300-15 and GAL300-15. If your line must stay oil-free, omit the lubricator and choose a plain GAFR instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply near 1.0 MPa if you need 0.9 MPa out.
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 GAFC300N15SNK FAQ
The working pressure 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. It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g. Recommended lubricant is ISO VG 32 or equivalent. The 40 um element filters the air, and the unit has a 1/2in port.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC300 body is 1/8in, so you can add a circular gauge later if you need to read the set pressure. Without one, the regulated output cannot be verified visually, so plan for a gauge if your process requires a confirmed setting.
