About the Airtac GAFC Air Service Unit GAFC300N10ASWK
This GAFC300N10ASWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air enters the first body where the 5 um element removes solids and moisture, and the regulator sets pressure to 0.15-0.9 MPa (20-130 psi). The lubricator then adds a controlled oil mist downstream, so oil never travels back through the regulator seat.
The 3/8in port and 1020 g mass place it in the mid-size class, between the lighter GAFC200 and the heavier GAFC400. Its 60 cc condensate bowl and 98 cc oil bowl determine service intervals, and the nylon bowl material is a build choice that does not change the shared -5 to 70 C temperature rating. The automatic drain clears condensate without an operator, and the circular gauge reads 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 GAFC300N10ASWK Is Used
Precision Valve Control
Feed a bank of pneumatic valves on a small assembly station, where the 5 um element protects fine orifices from particle wear and the regulated pressure holds consistent actuation.
Conveyor Drive Units
Supply a short conveyor section with a single air motor or cylinder, using the automatic drain to handle condensate in a line that runs continuously through shifts.
Machine Tool Lubrication
Deliver filtered, regulated air with metered oil mist to a small machining fixture's guide ways, where the 98 cc oil bowl supports extended operation between refills.
Is the Airtac GAFC Air Service Unit GAFC300N10ASWK the Right Air-Prep Unit?
Choose this GAFC300N10ASWK when you need 3/8in ports with a 5 um element for finer filtration, and an automatic drain for unattended operation. The nylon bowl is specified by the N before the port code, while the K suffix indicates the reverse-flow valve is fitted. The standard pressure type regulates from 0.15 to 0.9 MPa (20-130 psi), and the circular gauge is included, reading MPa/psi on the PT thread. For a lower pressure ceiling, the L type tops out at 0.4 MPa, but this model suits the full standard band.
If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. Spare parts are orderable as GAFR300-10 and GAL300-10, both matching this body and port. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range.
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 GAFC300N10ASWK FAQ
The GAFC300N10ASWK operates from 0.15 to 0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 60 cc condensate bowl and a 98 cc oil bowl, weighs 1020 g, and uses a 5 um filter element.
The automatic drain, indicated by the A in the code, clears condensate from the 60 cc bowl without requiring an operator to manually open a valve. This is useful for lines that run unattended or in wet conditions where moisture accumulates quickly. The nylon bowl is visible for level checks, and the drain operates automatically as condensate builds.
