About the Airtac GAFC Air Service Unit GAFC300N10SNWK
This AirTAC GAFC300N10SNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. With a 3/8in port and a 1020 g mass, it suits machine headers feeding several actuators. The nylon bowl holds 60 cc of condensate, while the oil bowl holds 98 cc.
The 5 um element traps finer particles than the standard 40 um grade, protecting precision valves downstream. It regulates from 0.15 to 0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum supply. No gauge is fitted, so the 1/8in gauge connection must be used if a pressure readout is added later.

Constituent units, orderable separately as spares: GAFR300-10 filter & regulator, GAL300-10 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC300N10SNWK Is Used
Precision Valve Protection
The 5 um element in this GAFC300N10SNWK shields sensitive pneumatic valves on a CNC tool changer from fine abrasive particles that would otherwise score spool surfaces.
Assembly Line Lubrication
Feed a 3/8in header on a small assembly conveyor, where the 98 cc oil bowl keeps multiple cylinder-mounted lubricators running between shifts without frequent topping up.
Machine Tool Air Prep
Mount this 1020 g unit on a lathe's coolant valve bank, using the 60 cc condensate bowl to collect moisture from a warm shop line before it reaches the tool clamp cylinders.
Is the Airtac GAFC Air Service Unit GAFC300N10SNWK the Right Air-Prep Unit?
Choose this GAFC300N10SNWK when a 3/8in port and 5 um filtration are required. The nylon bowl is specified by the N before the port code, while the N after the port means no gauge is supplied. The semi-auto drain dumps condensate on pressure drop, with a manual backup for on-demand use. The reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. The PT thread carries a MPa/psi gauge scale if one is installed.
For oil-free lines, select a plain GAFR300-10 filter-regulator instead of this lubricator-equipped set. Spare parts are the GAFR300-10 and GAL300-10, both orderable separately. With a 1.0 MPa max supply, there is about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the inlet 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 GAFC300N10SNWK FAQ
This F.R.L. combination works from 0.15 to 0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C and needs ISO VG 32 oil in the lubricator. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g with a 3/8in port.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so a gauge can be added later if a pressure readout is needed. The PT thread would use a MPa/psi scale on any gauge fitted.
