About the Airtac GAFC Air Service Unit GAFC300N10AL
This AirTAC GAFC300N10AL is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared bracket. The 3/8in port and 1020 g mass place it in the mid-size class, suitable for a single machine station or a small assembly line. Air is filtered and regulated inside the first body, then the lubricator adds a controlled oil mist downstream, so the regulator seat never sees oil.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and a nylon bowl. The automatic drain clears condensate without an operator, and the 60 cc drain bowl plus 98 cc oil bowl set the service rhythm. A circular gauge is fitted, reading MPa and psi on the default PT thread.

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 GAFC300N10AL Is Used
Precision Pressure Setting
Set a precise 0.3 MPa for a delicate pneumatic clamping fixture on a CNC machine, where the lower-pressure range gives finer adjustment below 0.4 MPa.
Small Assembly Station
Feed a single-station assembly bench with filtered, regulated, and lubricated air for pneumatic screwdrivers and small actuators, with the automatic drain handling condensate.
Laboratory Air Supply
Provide clean, oil-misted air at a controlled low pressure for a lab test rig that cycles a small cylinder, where the 40 um element protects the valve.
Is the Airtac GAFC Air Service Unit GAFC300N10AL the Right Air-Prep Unit?
Choose the GAFC300 body for a 3/8in port with a 60 cc condensate bowl and 98 cc oil bowl, stepping down from the GAFC400's 100 cc and 185 cc bowls when space or flow is lighter. The nylon bowl is specified by the N code before the port; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The A code specifies an automatic drain, removing the need for manual or semi-auto dumps. The L type tops out at 0.4 MPa, so if the machine may ever need more pressure, select the S type instead. The 40 um element is standard; the W option fits a 5 um element for finer filtration. The gauge is fitted and reads MPa/psi on the PT thread. Spares are the GAFR300-10 filter-regulator and GAL300-10 lubricator, both orderable separately. A 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 GAFC300N10AL FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 60 cc drain bowl and a 98 cc oil bowl, and weighs 1020 g.
The L specifies the lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. This suits applications that need a precise, low setpoint. The 1.0 MPa max supply leaves about 0.6 MPa of headroom above the top of this range.
