Airtac GAFR Adjustable Filter Regulator GAFR600C20SK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20SK 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 3/4" ports, a 40 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 GAFR600C20SK
The GAFR600C20SK is a filter and regulator combined into one robust body, handling both filtration and pressure control in a single installation. This model offers a 3/4in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), and a 40 um filter element, with a metal bowl and a semi-auto plus manual drain system.
Weighing 1880 g, this unit is built for heavy-duty lines and includes a circular gauge with MPa/psi scale. The balanced regulator mechanism holds the outlet steady as supply pressure varies, while the pressed-in self-locking knob resists drift from vibration, ensuring stable performance in demanding environments.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC600-20 F.R.L. combination instead.

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 GAFR600C20SK Is Used
Machine Header Supply
Feed a multi-station machine header with a steady 3/4in air supply, using the 205 cc metal bowl to handle heavy condensate from a long main line.
High-Flow Conveyor Line
Regulate air for a long conveyor system where the 1880 g body and 12000 L/min flow envelope at 0.7 MPa inlet support multiple actuators without pressure drop.
Industrial Process Skid
Mount on a process skid where the metal bowl resists rough handling and the semi-auto drain allows scheduled maintenance in a permanent installation.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20SK the Right Air-Prep Unit?
Choose the GAFR600 body for high-flow applications, as its flow curve is plotted to 12000 L/min at 0.7 MPa inlet. This metal-bowl model is the only option for the 600 series, and the standard type is the sole pressure variant, offering 0.15-0.9 MPa (20-130 psi). The included mounting bracket suits panel or frame installation, and the semi-auto plus manual drain provides flexible condensate removal. The 40 um element is the standard choice, and the PT thread comes with an MPa/psi gauge scale. The reverse-flow (reflux) valve is fitted as an ordering difference. For lines needing oil downstream, the matching GAFC600-20 combination adds a lubricator. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa for maximum output.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ 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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1880 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 GAFC600-20 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C20SK FAQ
The GAFR600C20SK operates from 0.15-0.9 MPa (20-130 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. It has a 205 cc drain bowl and weighs 1880 g.
The K indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from models without it. For detailed function, please confirm from the datasheet.
