About the Airtac GAFC Air Service Unit GAFC300N10ASNK
This AirTAC F.R.L. combination pairs a filter-regulator body with a lubricator on a single T-bracket, so the air is cleaned and set to pressure before a metered oil mist is added downstream. The 3/8in port and 1020 g mass place it in the mid-size GAFC300 class, suited to a machine header feeding several actuators.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element as standard. The nylon bowl is specified by the N code, and the automatic drain clears condensate without an operator. A reverse-flow valve is fitted, shown as a separate symbol in the catalogue.

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 GAFC300N10ASNK Is Used
Precision jig clamping
Feed a 3/8in line to a pneumatic jig that clamps parts during drilling. The 40 um element protects the clamp valve, while the automatic drain keeps the bowl from filling on a shift with high humidity.
Multi-actuator machine header
Supply a small machine header that runs three cylinders in sequence. The 60 cc condensate bowl and 98 cc oil bowl give a reasonable service window between checks for a mid-size line.
Instrument air branch
Protect a pressure sensor or a flow meter on a branch line. The filter-regulator stage removes solids and moisture, and the lubricator adds oil only if the downstream device needs it.
Is the Airtac GAFC Air Service Unit GAFC300N10ASNK the Right Air-Prep Unit?
Choose the GAFC300N10ASNK when a 3/8in port needs filtered, regulated air with automatic condensate removal. The nylon bowl is a build choice, but the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm it suits your surroundings. The N after the port means no gauge is supplied; the 1/8in gauge connection is there if you add one later. The K code adds the reverse-flow valve, and the PT thread carries an MPa/psi scale if a gauge is fitted. Spares are the GAFR300-10 filter-regulator and GAL300-10 lubricator, both orderable separately. 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 (3/8" 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N10ASNK 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). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can fit a gauge later if you need to read the set pressure. The PT thread on the port would use an MPa/psi scale for a compatible gauge.
