Airtac GAFR Adjustable Filter Regulator GAFR300C08SWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C08SWK 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 1/4" 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 GAFR300C08SWK
The GAFR300C08SWK is a filter & regulator that combines air filtration and pressure regulation in a single body, eliminating the need for separate GAF and GAR units. This 1/4in model operates from 0.15-0.9 MPa (20-130 psi) and comes with a 5 um element for finer particle removal.
Its metal bowl and semi-auto plus manual drain handle condensate in a 60 cc bowl, while the pressed-in self-locking knob resists set-pressure drift from vibration. The unit weighs 500 g and includes a circular gauge with MPa/psi scale, plus a reverse-flow valve fitted as an ordering difference.

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 GAFR300C08SWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station, where the 5 um element protects fine internal passages from particle wear.
Single actuator line
Supply a single cylinder or rotary actuator on a packaging machine, with the semi-auto drain letting operators manually purge condensate during shift changes.
Test bench air supply
Provide clean, regulated air to a lab test fixture, where the metal bowl resists rough handling and the gauge allows quick pressure verification.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C08SWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in ports with a 60 cc drain bowl and 500 g mass, sitting between the smaller GAFR200 and larger GAFR400. The metal bowl suits demanding environments, while the 5 um element traps finer particles than the standard 40 um grade, though it requires more frequent service. This model ships with the mounting bracket, a circular gauge, and both semi-auto and manual drains; the reverse-flow valve is fitted per the K code. If your line needs oil downstream, order the matching GAFC300-08 combination instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near 1.0 MPa for full regulation.
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
- ✓ 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 GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C08SWK FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C, drain bowl capacity is 60 cc, and the unit weighs 500 g. It uses a 5 um element and has a 1/4in port.
The K indicates a reverse-flow (reflux) valve is fitted to this unit. It is drawn as a separate pneumatic symbol in the catalogue and represents an ordering difference from standard models. The catalogue defers its function to a page not included in our data, so we recommend consulting the full AirTAC documentation for operational details.
