Airtac GAFR Adjustable Filter Regulator GAFR600C25SJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25SJNWK 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 1" ports, a 5 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 GAFR600C25SJNWK
The GAFR600C25SJNWK is a filter and regulator combined into a single body, eliminating the need for separate units. It handles a 1 inch port and delivers a regulated output of 0.15-0.9 MPa (20-130 psi) while filtering the air to 5 um. This metal-bowl version is built for heavy-duty lines where a robust, permanent installation is required.
The unit's diversion structure spins incoming air to separate liquid water and solid particles into the 205 cc drain bowl. A balanced, self-locking regulator maintains the set outlet pressure, resisting drift from vibration. With no gauge fitted, the 1/4 inch gauge connection is available for adding one if needed.

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.

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 GAFR600C25SJNWK Is Used
Machine Header Supply
Feed a central header for a multi-station assembly machine. The 1 inch port and large bowl handle the volume and condensate of several actuators running continuously.
Instrument Air Pre-Filter
Use the 5 um element ahead of sensitive pneumatic controls. The fine filtration protects precision valves and regulators from particle wear.
Main Conveyor Line
Supply a long conveyor system with many air cylinders. The stable regulation and high flow envelope support consistent operation across the entire line.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25SJNWK the Right Air-Prep Unit?
This GAFR600 is the largest body in the series, with a 1 inch port and a flow envelope plotted to 12000 L/min at 0.7 MPa inlet. It is the right choice for a machine header or a multi-station line; the 205 cc drain bowl holds far more condensate than the 108 cc bowl of a GAFR500, meaning less frequent draining. The metal bowl is the only option for this body, and the standard pressure type is fixed. This model ships without the mounting bracket (J) and without a gauge (N), so plan for a panel mount or existing bracket and an added gauge if readout is required. The 5 um element (W) traps finer particles than the standard 40 um, which is better for precision valves but will need more frequent service. The semi-auto and manual drains are both fitted, and the PT thread is standard. The reverse-flow (reflux) valve is attached as an ordering difference. If the line needs oil downstream, the matching GAFC600-25 combination adds a lubricator. Note that 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 (1" 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 GAFC600-25 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR600C25SJNWK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 205 cc drain bowl and weighs 1880 g.
The 'N' code means no gauge is supplied, but the 1/4 inch gauge connection is there if you add one later. The 'J' code means the mounting bracket is not included, so you will need to use a panel mount or an existing bracket to support the 1880 g unit.
