About the Airtac GAFC Air Service Unit GAFC300N15SK
This AirTAC GAFC300N15SK is an F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body paired with a lubricator. Air enters the first body where the 40 um element removes moisture and solid particles, then the regulator sets pressure to 0.15-0.9 MPa (20-130 psi). The lubricator adds a controlled oil mist last, downstream of the regulator seat, so oil never travels back through the pressure-setting mechanism.
The 1/2in port and 1020 g mass place this unit in the mid-size GAFC300 class, a step up from the GAFC200's 590 g body. The nylon bowl is specified by the N code, and the 60 cc condensate bowl plus 98 cc oil bowl determine how often someone must attend the unit. A circular gauge is fitted, reading MPa and psi on the default PT thread scale.

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 GAFC300N15SK Is Used
Precision machining center
Feed a CNC machining center's tool changer and spindle air system with regulated pressure and metered lubrication, where the 1/2in port matches typical machine headers and the 40 um element protects sensitive valves.
Assembly line pneumatic tools
Supply a multi-station assembly line where operators use air screwdrivers and drills; the lubricator keeps tool internals oiled while the regulator maintains consistent torque by holding set pressure as line demand fluctuates.
Packaging machine air circuit
Run a carton erector or stretch wrapper's cylinders and actuators from this unit, where the 98 cc oil bowl supports longer shifts between refills and the semi-auto drain clears condensate automatically at each pressure cycle.
Is the Airtac GAFC Air Service Unit GAFC300N15SK the Right Air-Prep Unit?
Choose the GAFC300N15SK when a 1/2in port suits the air demand and the 3500 L/min flow envelope at 0.7 MPa inlet provides the sizing reference. The nylon bowl is named by the N code, and the shared specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of bowl material, so confirm nylon suits the environment. The semi-auto drain dumps condensate each time pressure drops, while the manual drain gives on-demand control; the reverse-flow valve is fitted per the K code. The circular gauge reads in MPa and psi, matching the PT thread, and the 40 um element handles general shop air. For lines that must stay oil-free, omit the lubricator and select a plain GAFR300-15 filter-regulator instead. Spare units are orderable separately as GAFR300-15 and GAL300-15. With a 1.0 MPa max supply, there is only about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply 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 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 GAFC300N15SK FAQ
The GAFC300N15SK operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g with a 1/2in port.
The K code indicates the reverse-flow (reflux) valve is fitted to this GAFC300N15SK. The catalogue shows this valve as a separate pneumatic symbol. It is an ordering difference from models without the K code; the valve is already attached when the unit arrives.
