About the Airtac GAFC Air Service Unit GAFC300C10LK
This AirTAC GAFC300C10LK 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 size and 1020 g mass place it in the mid-range class, a step up from the lighter GAFC200 for feeding multiple actuators. Air is filtered and set to pressure in the first body, then the lubricator adds a controlled oil mist last, so oil never travels back through the regulator seat.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The 40 um element handles standard shop air, while the metal bowl and semi-auto plus manual drains suit a fixed installation where condensate is checked on a schedule. A circular gauge is fitted, reading MPa and psi for 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 GAFC300C10LK Is Used
Precision pressure setting
Set a precise 0.3 MPa (43 psi) for a delicate air bearing or a light clamping fixture in a machining cell, where the lower-pressure range gives finer adjustment than a standard regulator.
Lubricated pneumatic tools
Feed a die grinder or a small air motor on a workbench, where the lubricator adds ISO VG 32 oil mist to protect the tool's internal vanes and bearings.
Bench assembly station
Power a pneumatic press or a parts feeder on an assembly bench, using the 3/8in port to connect to a local distribution header and the metal bowl for a fixed, non-moving setup.
Is the Airtac GAFC Air Service Unit GAFC300C10LK the Right Air-Prep Unit?
Choose the GAFC300C10LK when your circuit needs regulated air at or below 0.4 MPa (58 psi) and you want the convenience of a combined filter-regulator with lubricator. The metal bowl is a build choice for a fixed machine location; confirm it suits your environment, as the catalogue lists the same 1.0 MPa maximum and -5 to 70 C range for all bowl materials. The semi-auto drain dumps condensate each time pressure drops, with a manual backup for on-demand emptying, and the 60 cc drain bowl plus 98 cc oil bowl set the service interval. The 5 um element option is available if you need finer filtration, and the reverse-flow valve fitted here is shown as a separate symbol in the catalogue. For oil-free lines, omit the lubricator and select a plain GAFR filter-regulator instead. Spare parts are the GAFR300-10 filter-regulator and GAL300-10 lubricator, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's regulated band.
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 GAFC300C10LK FAQ
The GAFC300C10LK 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). It works in temperatures from -5 to 70 C and should not be allowed to freeze. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Use ISO VG 32 or equivalent lubricant. The complete unit weighs 1020 g.
The K indicates that a reverse-flow (reflux) valve is fitted to this unit. The catalogue shows this valve as a separate pneumatic symbol. It is an ordering difference to be aware of; the valve is included with this model as standard.
