Airtac GAFR Adjustable Filter Regulator GAFR600C20ASK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20ASK 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 GAFR600C20ASK
The GAFR600C20ASK is a filter and regulator combined into a single body, handling both filtration and pressure control without a separate lubricator. It uses a 3/4in port, a 40 um element, and a metal bowl, with a working range of 0.15-0.9 MPa (20-130 psi).
This 1880 g unit is the largest in the GAFR series, with a 205 cc drain bowl and a flow curve plotted to 12000 L/min at 0.7 MPa inlet. The balanced regulator holds the outlet steady as supply pressure varies, and the pressed-in self-locking knob resists drift from vibration.

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 GAFR600C20ASK Is Used
Machine header supply
Feed a multi-station assembly machine with stable, filtered air at 0.15-0.9 MPa. The 3/4in port and 12000 L/min envelope handle several actuators running simultaneously.
Conveyor line pressure
Set a steady pressure for pneumatic conveyors or sorting stations. The automatic drain clears condensate without stopping production, and the metal bowl suits industrial environments.
Process equipment
Supply filtered air to process valves or positioning fixtures. The balanced regulator keeps outlet pressure stable as inlet fluctuates, supporting consistent cycle times.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20ASK the Right Air-Prep Unit?
Choose this GAFR600 when you need a high-capacity filter-regulator for a machine header or multi-station line. The 3/4in port and 205 cc drain bowl reduce how often you need to check condensate compared to smaller bodies like the GAFR500 with its 108 cc bowl. The metal bowl is standard for this size, and the automatic drain handles wet or unattended lines without manual intervention. The included bracket supports the 1880 g mass, and the fitted gauge with MPa/psi scale lets you read set pressure directly. The 40 um element suits general shop air, and the K code adds a reverse-flow valve as an ordering difference. If you need lubrication downstream, order the GAFC600-20 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 (3/4" 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 GAFR600C20ASK FAQ
The GAFR600C20ASK is a filter-regulator with a 3/4in port, working range 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, 205 cc drain bowl, and 1880 g weight. It has a 40 um element and an automatic drain.
The K code indicates a reverse-flow (reflux) valve is fitted. This is an ordering difference from models without the K code; the catalogue defers its function to a separate page, so no operational details are provided here.
