About the Airtac GAFC Air Service Unit GAFC300N10AS
This GAFC300 N10AS is a two-piece F.R.L. combination: a filter-regulator body followed by 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 a single machine station or a small multi-actuator line. Air enters the first body where solids and moisture drop out and pressure is set to 0.15-0.9 MPa (20-130 psi), then the lubricator meters ISO VG 32 oil mist into the flow last.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, so the service interval is driven by how wet the supply is rather than by frequent checks. The automatic drain clears water without an operator, which suits lines that run unattended. A circular gauge is fitted and reads in MPa and psi, matching the PT thread. The catalogue flow curve for this body is plotted to 3500 L/min at 0.7 MPa inlet, a sizing envelope rather than a rated capacity.

Where the Airtac GAFC Air Service Unit GAFC300N10AS Is Used
Precision valve control
Feed a bank of small solenoid valves on a pick-and-place unit, where the 40 um element and regulated 0.15-0.9 MPa range keep pilot air consistent and the automatic drain handles condensate from a humid compressor.
Single-station conveyor
Supply a 3/8in ported conveyor stop cylinder or a small indexing table. The 98 cc oil bowl keeps the lubricator filled for a full shift, and the nylon bowl suits a washdown area where a clear bowl might cloud.
Machine tool coolant valve
Run a coolant control valve on a CNC machine where the 60 cc drain bowl collects water from a wet line and the automatic drain clears it without stopping production. The 1020 g body mounts securely on a machine frame.
Is the Airtac GAFC Air Service Unit GAFC300N10AS the Right Air-Prep Unit?
Choose the GAFC300N10AS when a 3/8in port and a 1020 g body fit the machine layout. The nylon bowl is a build choice, not a performance upgrade: the 1.0 MPa max pressure and -5 to 70 C range are identical across PC, metal and nylon, so confirm the material suits your surroundings. The automatic drain is the key option here, removing condensate without manual intervention. The 40 um element handles general shop air; step to the 5 um W option if the downstream valves need finer filtration. The PT thread carries a gauge scale in MPa and psi, so operators read the setpoint in familiar units. Spare parts are orderable as the GAFR300-10 filter & regulator and the GAL300-10 lubricator, both with the same body-port suffix. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the inlet pressure near 1.0 MPa if you need the full 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 GAFC300N10AS FAQ
The GAFC300N10AS is a two-piece F.R.L. combination with a 3/8in port. It regulates air from 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). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g and the flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The A code specifies an automatic drain, which expels condensate from the 60 cc bowl without an operator. This is different from the blank drain option, which includes both a semi-auto drain that dumps on pressure drop and a manual drain for on-demand use. The automatic version is suited for lines that run continuously or in unattended locations.
