Airtac GAFR Adjustable Filter Regulator GAFR600C20SJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20SJK 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 GAFR600C20SJK
The GAFR600C20SJK is a filter and regulator combined into a single body, handling both filtration and pressure control for high-flow pneumatic systems. This unit operates in the 0.15-0.9 MPa (20-130 psi) range with a 40 um element, and its metal bowl is the only option for this size class.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 205 cc drain bowl, while the balanced regulator holds the set pressure steady as supply varies. The pressed-in self-locking knob resists drift from vibration, and the circular gauge with clip and magnifier saves panel space.

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 GAFR600C20SJK Is Used
Machine Header Supply
Feed a multi-station assembly machine header where several actuators draw air simultaneously. The 3/4in port and 12000 L/min plotted flow envelope at 0.7 MPa inlet keep pressure stable across the line.
Main Conveyor Line
Protect a long conveyor system with multiple pneumatic stops and guides. The 205 cc drain bowl handles condensate from wet plant air, and the metal bowl suits industrial environments without needing frequent replacement.
High-Cycle Production Cell
Run a high-cycle production cell with precision valves that need clean, regulated air. The 40 um element filters solid particles, while the self-locking knob keeps the set pressure from drifting during continuous vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20SJK the Right Air-Prep Unit?
This GAFR600 body is the largest in the series, with a 3/4in port and a 1880 g mass that demands a solid panel or frame mount rather than tubing support. The metal bowl is standard for this size, and the semi-auto plus manual drain gives you both automatic condensate release and a manual override for scheduled maintenance. The J code means no mounting bracket is included, so plan for an existing bracket or panel mount. The K code indicates the reverse-flow (reflux) valve is fitted, and the PT thread comes with an MPa/psi gauge scale. If your line needs lubrication 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, so plan your inlet pressure near the maximum to reach the full regulated 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 GAFR600C20SJK FAQ
The GAFR600C20SJK is a filter & regulator with a 3/4in port, working pressure range of 0.15-0.9 MPa (20-130 psi), max pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 205 cc, the unit weighs 1880 g, and the flow curve is plotted to 12000 L/min at 0.7 MPa inlet.
The K code indicates a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference shown as a separate pneumatic symbol in the catalogue. The specific function is detailed on a page not included in our data, so consult the full AirTAC catalogue for operational details.
