Airtac GAFR Adjustable Filter Regulator GAFR200N08ASWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ASWK 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 1/4" 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 GAFR200N08ASWK
The GAFR200N08ASWK is a filter and regulator combined in a single body, eliminating the need for separate GAF and GAR units. This 1/4in port model weighs just 290 g, making it ideal for compact machine builds where rail space is tight. Its nylon bowl and automatic drain handle condensate in the 25 cc drain bowl without manual intervention.
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) and filters with a 5 um element. The balanced regulator mechanism holds outlet pressure steady as supply varies, while the pressed-in self-locking knob resists drift from vibration. A reverse-flow valve is fitted per the K code, and the circular gauge with MPa/psi scale is included.

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 GAFR200N08ASWK Is Used
Precision valve control
Feed a single precision pneumatic valve or small actuator with stable 0.15-0.9 MPa air, filtered to 5 um to protect fine internal clearances.
Compact bench jig
Mount on a small assembly jig or test fixture where the 290 g weight and 1/4in port fit tight spaces, with the automatic drain reducing maintenance.
Instrument air supply
Supply a lab instrument or sensitive sensor with 5 um filtered air, using the included gauge to verify set pressure and the self-locking knob to hold it.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ASWK the Right Air-Prep Unit?
Choose the GAFR200 body for small actuators, jigs, or single-station fixtures. The 1/4in port suits low-flow circuits, and the 2000 L/min flow envelope (plotted at 0.7 MPa inlet) helps size against the GAFR300's 3500 L/min curve if you need more capacity. The nylon bowl offers a build choice without changing the common 1.0 MPa max pressure or -5 to 70 C temperature rating. The automatic drain (A) handles wet or unattended lines, while the 5 um element traps finer particles than the standard 40 um for precision valves. The bracket is included, the gauge is fitted with PT thread showing MPa/psi, and the reflux valve is present as an ordering difference. If oil is needed downstream, order the matching GAFC200-08 combination instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near 1.0 MPa for full output.
Quick checklist
- ✓ Body size for your peak flow (1/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 290 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 GAFC200-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR200N08ASWK 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. The drain bowl holds 25 cc, the unit weighs 290 g, and the flow curve is plotted to 2000 L/min at 0.7 MPa inlet.
The K indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from models without K; the catalogue defers its function to a separate page not included in our data, so we do not explain its operation.
