About the Airtac GAFC Air Service Unit GAFC300N08LN
This AirTAC GAFC300N08LN is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure control, then the lubricator adds a metered oil mist downstream. With a 1/4in port and a 1020 g mass, it suits compact machine builds where panel space is at a premium.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the nylon bowl holds 60 cc of condensate while the oil bowl holds 98 cc. The 40 um element traps standard workshop particles. No gauge is supplied, so the 1/8in gauge connection must be used if a readout is added later.

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 GAFC300N08LN Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a benchtop assembly fixture. The lower-pressure range protects delicate workpieces from over-force while the lubricator keeps the clamp cylinder cycling smoothly.
Lab Air Bench
Supply a small laboratory test rig that needs regulated air below 0.4 MPa. The 60 cc condensate bowl handles moisture from a humid compressor line, and the nylon bowl resists incidental lab splashes.
Paint Spray Booth
Run a single airbrush or small spray gun at a controlled low pressure. The 98 cc oil bowl delivers consistent mist for the tool's internal lubricator, and the 1/4in port matches common spray equipment.
Is the Airtac GAFC Air Service Unit GAFC300N08LN the Right Air-Prep Unit?
Choose the GAFC300N08LN when your circuit needs a 1/4in port and a regulated ceiling of 0.4 MPa (20-58 psi). The nylon bowl is a material choice that does not change the shared 1.0 MPa (145 psi) maximum pressure or the -5 to 70 C temperature range, so confirm it suits your environment. The semi-auto drain dumps condensate on pressure drop, with a manual override for on-demand draining, and the 40 um element is the standard grade. The PT thread carries an MPa/psi gauge scale if you fit a gauge later. Orderable spares are the GAFR300-08 filter-regulator and the GAL300-08 lubricator. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N08LN FAQ
This lower-pressure F.R.L. combination works from 0.15 to 0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 60 cc condensate bowl, a 98 cc oil bowl, and weighs 1020 g. The 40 um element handles standard filtration, and the PT thread is standard.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a compatible pressure gauge if you need to read the setpoint. Without one, you cannot verify the regulated pressure visually, so plan to fit a gauge for applications where the exact pressure matters.
