About the Airtac GAFC Air Service Unit GAFC300N10ASN
This AirTAC GAFC300N10ASN 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. The 3/8in port and 1020 g mass place it in the mid-size class, suited for feeding a small machine header or a few actuators. Air is filtered and regulated first, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element and an automatic drain that clears condensate without an operator. The nylon bowl holds 60 cc of condensate, while the separate oil bowl holds 98 cc. No gauge is supplied; the 1/8in gauge connection allows one to be added later if the set pressure needs to be read.

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 GAFC300N10ASN Is Used
Precision valve stations
Feed a bank of precision pneumatic valves on a small assembly machine. The 40 um element protects valve internals, while the automatic drain keeps condensate from reaching sensitive components.
Small machine headers
Supply a compact machine header with 3/8in lines. The 1020 g unit mounts on a panel or frame, delivering filtered, regulated, lubricated air to a handful of cylinders.
Test bench air prep
Prepare air for a lab test bench where consistent pressure matters. The 0.15-0.9 MPa range covers typical test pressures, and the 98 cc oil bowl keeps lubricated tools running between refills.
Is the Airtac GAFC Air Service Unit GAFC300N10ASN the Right Air-Prep Unit?
Choose the GAFC300N10ASN when you need a 3/8in F.R.L. combination with an automatic drain and a nylon bowl. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating are identical across all bowl materials, so confirm it suits your environment. The automatic drain is ideal for unattended lines, and the 40 um element handles standard shop air; step up to the W option for 5 um filtration if you feed precision valves. The PT thread carries a gauge scale in MPa/psi, but this model ships without a gauge - the 1/8in connection is there if you add one. Spares are orderable as GAFR300-10 and GAL300-10. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom 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 GAFC300N10ASN FAQ
The GAFC300N10ASN operates at 0.15-0.9 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. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g.
The N after the port code means no gauge is supplied. The 1/8in gauge connection is present on the body, so you can add a circular gauge later if you need to read the set pressure directly. The PT thread option would use an MPa/psi scale if a gauge is fitted.
