About the Airtac GAFC Air Service Unit GAFC300N15SWK
This GAFC300 F.R.L. combination brings filtering, pressure regulation and lubrication together as two bodies on one T-bracket. The first body houses the filter element and the regulator, so air is cleaned and set to pressure before it moves on; the second body is the lubricator, which meters oil mist into the flow last. With a 1/2in port and a 1020 g mass, it suits machine headers feeding several actuators or a single large cylinder.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 5 um element traps finer particles than the standard 40 um grade, which protects precision valves but calls for more frequent element service. The nylon bowls hold 60 cc for condensate and 98 cc for oil, and the semi-auto drain dumps water each time pressure drops while the manual drain gives on-demand control. A circular gauge is fitted, reading in MPa and psi for the PT thread.

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 GAFC300N15SWK Is Used
Precision valve protection
Feed a bank of pneumatic valves on a CNC machine with the 5 um element, which stops fine abrasive dust from scoring spool surfaces and extends valve life between overhauls.
Multi-station assembly line
Supply a 1/2in header on a small assembly station where several cylinders cycle frequently, using the 98 cc oil bowl to keep lubricant available across a full shift.
Test rig air preparation
Prepare air for a benchtop test fixture that needs regulated pressure and a fine filtration grade, with the gauge letting operators verify setpoint before each run.
Is the Airtac GAFC Air Service Unit GAFC300N15SWK the Right Air-Prep Unit?
Choose the GAFC300 body for medium-flow lines up to a 1/2in port, and step down to the GAFC200 if you need only 1/4in or 1/8in connections. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits your environment before ordering. The 5 um element is the right call for sensitive equipment, while the 40 um grade handles general shop air with less maintenance. The semi-auto and manual drains are both fitted here, so condensate can be purged automatically on pressure drop or manually when you choose. The reverse-flow (reflux) valve is fitted, and the catalogue shows it as a separate pneumatic symbol. Spare parts are the GAFR300-15 filter-regulator and the GAL300-15 lubricator, both orderable separately. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near the maximum 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 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 GAFC300N15SWK 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 proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C and the fluid is air. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32 or equivalent. The complete unit weighs 1020 g.
The K code specifies the reverse-flow (reflux) valve, which the catalogue draws as a separate pneumatic symbol. The W code specifies the 5 um element, which captures finer particles than the standard 40 um grade. This combination suits applications where backflow protection and fine filtration are both specified, such as precision instrumentation loops.
