Airtac GAFR Adjustable Filter Regulator GAFR600C20SJNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C20SJNK 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 GAFR600C20SJNK
The GAFR600C20SJNK is a filter & regulator in one body, combining a diversion filter and a balanced pressure regulator without any lubricator. This 3/4in unit handles 0.15-0.9 MPa (20-130 psi) with a 40 um element, and its metal bowl collects condensate.
Weighing 1880 g, this GAFR600 sits at the top of the series and is built for machine headers. The pressed-in self-locking knob resists set-pressure drift from vibration, while the single 205 cc drain bowl defines the service interval for this size class.

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 GAFR600C20SJNK Is Used
Machine Header Supply
Feed a multi-station assembly machine with a single 3/4in filtered and regulated air supply, using the 12000 L/min envelope at 0.7 MPa inlet to size downstream equipment.
Conveyor Line Control
Regulate air for a long conveyor system where the 205 cc metal bowl handles condensate from wet plant air, and the self-locking knob keeps pressure stable despite line vibration.
Heavy Automation Cell
Supply a robotic welding cell with clean, regulated air at 0.15-0.9 MPa, using the 40 um element to protect precision valves and the semi-auto drain for scheduled maintenance.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C20SJNK the Right Air-Prep Unit?
Choose GAFR600 when you need the largest flow envelope in the series, plotted to 12000 L/min at 0.7 MPa inlet, and a 3/4in port. The metal bowl is the only option on this body, and the semi-auto+manual drain gives you both automatic condensate release and a manual override. The J code means no mounting bracket is included, so plan for a panel mount or existing frame. The N code omits the gauge, but the 1/4in gauge connection is ready for a later addition. The K code adds the reverse-flow (reflux) valve as an ordering difference. If oil is needed downstream, order the matching GAFC600-20 combination instead. Max supply 1.0 MPa 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 GAFR600C20SJNK FAQ
Pressure range is 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. The drain bowl holds 205 cc and the unit weighs 1880 g.
The N code omits the gauge, leaving a 1/4in gauge connection for adding one later. The J code excludes the mounting bracket, so you must use a panel mount or existing bracket. The K code adds a reverse-flow (reflux) valve as an ordering difference.
