About the Airtac GAFC Air Service Unit GAFC300N10SN
This AirTAC GAFC300N10SN is an F.R.L. combination built from two units on a T-shape bracket: the GAFR300-10 filter-regulator handles filtration and pressure setting in one body, while the GAL300-10 lubricator adds a controlled oil mist downstream. With a 3/8" port and a 1020 g mass, it suits medium-size machines where a proper panel or frame mount is expected rather than support from the tubing.
The nylon bowl holds 60 cc of condensate and the oil bowl holds 98 cc, so the service interval is driven by how often these fill. The standard pressure range is 0.15-0.9 MPa (20-130 psi), the element is 40 um, and the semi-auto drain dumps on each pressure drop while the manual drain works on demand. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/8" gauge connection.

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 GAFC300N10SN Is Used
Precision jig clamping
Feed a 3/8" line to a multi-point clamping jig on a CNC fixture, where the 0.15-0.9 MPa range covers typical work-holding pressures and the 40 um element protects fine valve pilots.
Medium conveyor drive
Supply a 3/8" port to a belt conveyor's pneumatic tensioner and guide rollers, using the 98 cc oil bowl to keep the lubricator topped up across a full shift.
Assembly station air prep
Mount on a panel to feed a bench assembly station with filtered, regulated air for screwdrivers and small actuators, with the semi-auto drain clearing condensate at each start-up.
Is the Airtac GAFC Air Service Unit GAFC300N10SN the Right Air-Prep Unit?
Choose the GAFC300N10SN when a 3/8" port and a 1020 g body are right for the flow you need; the catalogue flow curve is plotted to 3500 L/min at 0.7 MPa inlet, so compare that envelope with the GAFC200's 1750 L/min curve when sizing down. The nylon bowl is a build choice, but the shared specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm nylon suits your environment. The semi-auto plus manual drain pair works for attended lines, while the A code swaps in an automatic drain for wet or unattended service. The 40 um element is the standard grade; the W code offers 5 um for finer filtration. No gauge is supplied, but the 1/8" connection accepts one later. Spares are the GAFR300-10 filter-regulator and the GAL300-10 lubricator, both orderable separately. Since the lubricator adds oil mist, choose a plain GAFR if the line must stay oil-free. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply near 1.0 MPa if you need 0.9 MPa out.
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 GAFC300N10SN FAQ
The GAFC300N10SN 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). The temperature range is -5 to 70 C and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8" gauge connection, so you can add a circular gauge later if you need to read the set pressure directly. Without one, the regulated pressure cannot be verified visually.
