About the Airtac GAFC Air Service Unit GAFC300C10ASNW
This AirTAC GAFC300C10ASNW 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 to a single machine station or a small production cell. Its metal bowl (60 cc condensate capacity) and 98 cc oil bowl set the service rhythm, while the 5 um element traps finer particles than the standard 40 um grade.
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Since the N after the port means no gauge is supplied, the 1/8in gauge connection is left open for a later addition. The automatic drain clears condensate without operator attention, and the unit is rated for -5 to 70 C with ISO VG 32 oil recommended for the lubricator.

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 GAFC300C10ASNW Is Used
Precision valve protection
Feed a bank of pneumatic pilot valves on a packaging line where the 5 um element keeps fine particles from clogging small orifices, while the automatic drain handles condensate from a humid compressor supply.
Small machine station
Supply a single assembly press or a dedicated workbench fixture with filtered, regulated, oil-misted air at 3/8in ports, using the 60 cc condensate bowl to gauge service intervals between shifts.
Instrument air pre-treatment
Prepare air for a sensitive gauging system or a flow meter where the 5 um element removes fine rust and pipe scale, and the lubricator adds a controlled oil mist downstream of the regulator seat.
Is the Airtac GAFC Air Service Unit GAFC300C10ASNW the Right Air-Prep Unit?
Choose this GAFC300C10ASNW when you need 3/8in ports and a 5 um element for finer filtration. The metal bowl is specified by the C code, a build choice for the surroundings; the common specification (1.0 MPa max, -5 to 70 C) applies regardless, so confirm the material suits your environment. The automatic drain (A) suits unattended or wet lines, while the standard type (S) regulates from 0.15 to 0.9 MPa (20-130 psi). The PT thread carries a gauge scale in MPa/psi, but no gauge is fitted here, so plan to add one at the 1/8in connection if operators need to read the setpoint. The 5 um element (W) demands more frequent service than the 40 um default, a trade-off for protecting precision valves. Spare parts are orderable as GAFR300-10 and GAL300-10. The catalogue flow curve for this body is plotted to 3500 L/min at 0.7 MPa inlet, useful for sizing against the GAFC200's 1750 L/min envelope. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated band, so plan the supply pressure accordingly.
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 GAFC300C10ASNW FAQ
The GAFC300C10ASNW operates from 0.15 to 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 is rated for -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g. The 5 um element filters the air and the automatic drain clears condensate.
The N after the port code specifies no gauge is supplied, so you cannot read the set pressure directly on the unit. The gauge connection on the GAFC300 body is 1/8in, allowing you to add a compatible gauge later if operators need to verify the regulated pressure.
