About the Airtac GAFC Air Service Unit GAFC300N10LW
This AirTAC GAFC300N10LW is a two-piece F.R.L. combination: a filter-regulator body paired with a separate lubricator, mounted together on a T-bracket with quick clamps. The 3/8in port and 1020 g mass place it in the mid-range size class, suited for feeding a single machine station or a small bank of cylinders. It regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps fine particles before they reach sensitive valves.
The nylon bowl holds 60 cc of condensate, while the oil bowl holds 98 cc, and the circular gauge reads in MPa/psi. Because the lubricator adds oil mist downstream of the regulator, the regulator seat never sees oil. The semi-auto drain dumps condensate when pressure drops, and the manual drain handles it on demand. With a 1.0 MPa (145 psi) maximum supply, there is about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.

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 GAFC300N10LW Is Used
Fine Filtering for Precision Jigs
The 5 um element protects precision pneumatic jigs and fixtures on a machining line, where fine particles could otherwise score valve spools or clog tiny orifices.
Low-Pressure Assembly Stations
A 3/8in port and 0.15-0.4 MPa range suit a manual assembly bench using soft-acting cylinders for light pressing or part holding, where higher pressure could damage components.
Lubricated Actuator Circuits
Feeds a small bank of pneumatic actuators that need metered oil mist, such as a packaging machine's film-guide rollers, keeping moving parts lubricated without over-oiling.
Is the Airtac GAFC Air Service Unit GAFC300N10LW the Right Air-Prep Unit?
The L in this code sets the lower pressure range, topping out at 0.4 MPa instead of the standard 0.9 MPa. If your machine may ever need more than 0.4 MPa, this is the wrong part. The N before the port specifies a nylon bowl, and the W specifies the finer 5 um element, which suits precision equipment but will need more frequent service than the standard 40 um. The drain is the semi-auto plus manual pair, and the PT thread carries a gauge scaled in MPa/psi. For oil-free lines, omit the lubricator and choose a plain GAFR filter-regulator instead. Spare units are orderable as GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the 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 GAFC300N10LW FAQ
It operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and the recommended lubricant is ISO VG 32.
The W code specifies a 5 um filtering element instead of the standard 40 um. This traps much finer particles, which is useful for precision valves or instrument air. The trade-off is that the finer element will clog faster and require more frequent replacement or cleaning.
