Airtac GAFR Adjustable Filter Regulator GAFR300C10ASWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C10ASWK is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 3/8" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR300C10ASWK
The GAFR300C10ASWK is a filter & regulator in a single body, combining a diversion-type filter with a balanced pressure regulator. It handles a 3/8" port and delivers a steady 0.15-0.9 MPa (20-130 psi) outlet, with a 5 um element for finer filtration.
The metal bowl (60 cc) and automatic drain make it a low-maintenance choice for continuous operation. The pressed-in self-locking knob resists vibration drift, keeping the set pressure stable. This unit has no lubricator; it filters water and solids only.

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 GAFR Adjustable Filter Regulator GAFR300C10ASWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly machine, where the 5 um element protects fine internal passages from particle wear.
Wet utility line
Use on a factory air drop with frequent condensate, relying on the automatic drain to purge the 60 cc metal bowl without manual attention.
Test bench supply
Supply a stable 0.15-0.9 MPa output to a laboratory test jig, where the balanced regulator holds the setpoint as the shop air pressure fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C10ASWK the Right Air-Prep Unit?
Choose this GAFR300 for a 3/8" line where a 500 g body with a 60 cc metal bowl fits the mounting. The automatic drain suits unattended or wet lines, while the included bracket simplifies panel installation. The 5 um element traps finer particles than the standard 40 um, ideal for precision valves, though it will need more frequent service. The fitted gauge reads in MPa/psi, and the reverse-flow (reflux) valve is an ordering difference. If oil is needed downstream, order the matching GAFC300-10 combination instead. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C10ASWK FAQ
It is a filter & regulator with a 3/8" port, working pressure 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 60 cc drain bowl, and 500 g weight. It has a 5 um element and an automatic drain.
The K indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from the standard unit; the catalogue does not detail its function in our data.
