Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJNK 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 GAFR600C20ASJNK
The GAFR600C20ASJNK is a filter and regulator combined into a single body, handling both filtration and pressure control in one compact unit. This model uses a 3/4in port, operates from 0.15 to 0.9 MPa (20-130 psi), and comes with a 40 um element for standard industrial filtration.
The metal bowl holds 205 cc of condensate, and the automatic drain clears it without manual intervention. At 1880 g, this is a heavy-duty unit built for machine headers or multi-station lines, and it includes a reverse-flow valve as an ordering difference.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR600 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR600C20ASJNK Is Used
Machine Header Supply
Feed a multi-station machine header with a steady 3/4in air supply, using the automatic drain to handle condensate without stopping production.
High-Flow Assembly Line
Support a high-flow assembly line where the 12000 L/min plotted envelope at 0.7 MPa inlet provides ample sizing margin for multiple actuators.
Central Plant Air Drop
Install at a central plant air drop where the 205 cc metal bowl and automatic drain reduce maintenance visits on a busy production floor.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJNK the Right Air-Prep Unit?
Choose the GAFR600 when you need a 3/4in port with a 205 cc metal bowl and automatic drain. The J code means no mounting bracket is included, so plan for a panel mount or existing bracket. The N code means no gauge is fitted, but the 1/4in gauge connection is ready for one if you add it later. The K code adds a reverse-flow valve, and the PT thread suits standard gauge scales in MPa/psi. If your line needs oil downstream, order the matching GAFC600-20 combination instead. The 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 GAFR600C20ASJNK FAQ
The GAFR600C20ASJNK operates from 0.15 to 0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 205 cc, and the unit weighs 1880 g.
The N code means no gauge is supplied, leaving the 1/4in gauge connection open for a field-installed gauge. The J code omits the mounting bracket, so you can use an existing bracket or a panel mount. Both options reduce initial cost when you already have these components.
