Airtac GAFR Adjustable Filter Regulator GAFR600C25ASNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR600C25ASNK 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 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 GAFR600C25ASNK
The GAFR600C25ASNK is a filter and regulator combined into a single metal-bodied unit, sized for 1 inch lines with a 205 cc condensate bowl. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure from 0.15 to 0.9 MPa (20-130 psi) through its 40 um element.
This 1880 g unit includes a mounting bracket and an automatic drain, so it suits permanent installation on a machine header where condensate must be expelled without manual attention. The pressed-in self-locking knob keeps the pressure setting stable under vibration, and the reverse-flow (reflux) valve is fitted as an ordering difference.

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 GAFC600-25 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 GAFR600C25ASNK Is Used
Machine header supply
Feed a multi-station assembly machine with filtered, regulated air from a single 1 inch header point, using the automatic drain to handle condensate without line supervision.
High-flow conveyor line
Supply a long conveyor system with multiple actuators, where the 12000 L/min envelope at 0.7 MPa inlet supports the combined demand of several stations.
Permanent panel installation
Mount this 1880 g unit on a machine frame or panel using the included bracket, keeping the 205 cc bowl accessible for periodic inspection in a fixed location.
Is the Airtac GAFR Adjustable Filter Regulator GAFR600C25ASNK the Right Air-Prep Unit?
Choose the GAFR600 body when your line demands the largest flow envelope in the series, plotted to 12000 L/min at 0.7 MPa inlet, and a 205 cc drain bowl that needs far less frequent emptying than smaller units. The metal bowl is the only option on this body, and the standard pressure type covers 0.15-0.9 MPa (20-130 psi); the automatic drain handles wet or unattended lines, while the included bracket simplifies panel mounting. The 40 um element is the default, and the no-gauge version leaves a 1/4 inch connection if you add one later; the PT thread carries an MPa/psi scale. If your downstream equipment needs oil, order the matching GAFC600-25 combination instead, since this unit does not lubricate. 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 (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 GAFR600C25ASNK FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -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 N code means no gauge is supplied; the 1/4 inch gauge connection is available if you add one later. The K code indicates a reverse-flow (reflux) valve is fitted, which appears as a separate pneumatic symbol in the catalogue; its function is detailed on a page not included in our data.
