Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJN 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 GAFR600C20ASJN
The GAFR600C20ASJN is a filter and regulator combined into a single robust body, eliminating the need for separate units. This 3/4in port model handles high-flow lines with a 40 um element and an automatic drain, all within a 0.15-0.9 MPa (20-130 psi) working range.
Its 1880 g weight and metal bowl signal a heavy-duty build for industrial headers. The diversion structure spins air to separate liquid water and solid particles into the 205 cc condensate bowl, while the balanced regulator holds the set outlet pressure steady as supply varies.

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 GAFR600C20ASJN Is Used
Machine Header Supply
Feed a multi-station assembly machine with a single 3/4in line, using the automatic drain to handle condensate without manual checks.
High-Flow Conveyor System
Supply a long conveyor line with multiple actuators, relying on the 205 cc bowl to reduce drain frequency and the steady regulator to maintain consistent pressure.
Process Equipment Skid
Mount on a process skid where the 1880 g weight and metal bowl suit a permanent installation, with the no-gauge option simplifying the panel layout.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJN the Right Air-Prep Unit?
Choose the GAFR600 for large machine headers or multi-station lines where the 12000 L/min plotted flow envelope at 0.7 MPa inlet is needed. This model has a metal bowl (C), an automatic drain (A), and no mounting bracket (J) - plan for panel mounting or an existing frame. The standard pressure type (S) covers 0.15-0.9 MPa (20-130 psi), and the 40 um element is the default; select the W option for 5 um filtration. No gauge is fitted (N), but the 1/4in gauge connection is ready for a field-installed unit. If oil is needed downstream, order the matching GAFC600-20 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated 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 GAFR600C20ASJN FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. 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 a 1/4in connection for a field-installed gauge. The J code omits the mounting bracket, so you must use an existing bracket or panel mount. Both options reduce initial cost when these features are already present.
