Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJK 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 GAFR600C20ASJK
The GAFR600C20ASJK is a filter & regulator that combines a diversion filter and a balanced pressure regulator in a single metal body, eliminating the need for a separate filter and regulator pair. It handles 3/4in ports, operates from 0.15-0.9 MPa (20-130 psi), and uses a 40 um element to remove water and solid particles from the air stream.
This 1880 g unit is the largest in the GAFR series, with a 205 cc condensate bowl and an automatic drain for unattended operation. The pressed-in self-locking knob resists set-pressure drift from vibration, while 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 GAFR600C20ASJK Is Used
Machine Header Supply
Feed a central header for a multi-station assembly machine where several actuators and valves draw air simultaneously, relying on the 12000 L/min plotted envelope at 0.7 MPa inlet.
Conveyor Line Regulation
Set a stable 0.6 MPa (87 psi) for a long conveyor system with multiple pneumatic cylinders, using the balanced regulator to hold pressure as line demand fluctuates.
Heavy-Duty Press Station
Supply a large press or forming station that needs consistent air pressure and clean air, with the 40 um element protecting downstream precision valves.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20ASJK the Right Air-Prep Unit?
The GAFR600 is the top size class, with a 3/4in port and a flow curve plotted to 12000 L/min at 0.7 MPa inlet, making it suitable for machine headers or multi-station lines. The metal bowl is the only option for this body, and the automatic drain (A) handles condensate without manual intervention. The J code means no mounting bracket is included, so plan for a panel mount or existing bracket. The K code indicates a reverse-flow (reflux) valve is fitted; the gauge reads in MPa/psi with PT threads. If your line needs lubrication downstream, order the matching GAFC600-20 combination instead. 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 GAFR600C20ASJK FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C, drain bowl capacity is 205 cc, and weight is 1880 g.
The K code indicates a reverse-flow (reflux) valve is attached to the unit. It is an ordering difference from the standard model; the catalogue defers its function to a separate page not included in our data.
