Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJWK 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJWK
The GAFR200N08ALJWK is an AirTAC filter and regulator combined into a single body, saving rail space and reducing potential leak points versus separate units. This 1/4in version weighs 290 g and uses a nylon bowl, with a 5 um element that catches fine particles for sensitive equipment.
Its lower-pressure regulator operates from 0.15 to 0.4 MPa (20-58 psi), making it suitable for gentle applications. The automatic drain clears condensate without manual attention, and the fitted circular gauge shows the outlet pressure on an MPa/psi scale.

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 GAFR200N08ALJWK Is Used
Light Assembly Stations
Feed a single pneumatic screwdriver or small clamping cylinder on a bench assembly line, where the 5 um element protects precision tooling from fine abrasive particles.
Laboratory Air Supply
Provide filtered, regulated air at low pressure to a lab fixture or test jig that requires a gentle, steady 0.15-0.4 MPa supply without risk of over-pressurization.
Maintenance Workbench
Power a small blow gun or air brush at a service bench, relying on the automatic drain to handle condensate in a humid workshop without daily manual checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJWK the Right Air-Prep Unit?
Choose this GAFR200 body for small machines or single actuators needing a 1/4in connection, where its 2000 L/min flow envelope (plotted at 0.7 MPa inlet) provides ample capacity. The nylon bowl offers a lightweight alternative to metal, while the 5 um element suits precision valves or instrument air but requires more frequent service than a 40 um unit. This model has no mounting bracket (J), so plan for panel mounting or an existing support, and the automatic drain (A) is ideal for unattended or wet lines. The reverse-flow (reflux) valve (K) is fitted as an ordering difference, and the PT thread means the gauge reads in MPa/psi. If you need lubrication downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above this unit's 0.4 MPa regulated ceiling, so ensure your inlet pressure stays near 1.0 MPa to reach the top of the range.
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 GAFR200N08ALJWK FAQ
This filter & regulator has a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 25 cc drain bowl, and weighs 290 g. The unit includes a 5 um element, an automatic drain, a nylon bowl, and a fitted gauge with MPa/psi scale.
The automatic drain (A) clears condensate from the 25 cc bowl without manual intervention, ideal for wet or unattended lines. The lower-pressure type (L) limits output to 0.15-0.4 MPa, which is safer for delicate equipment that must never see higher pressures. Together they suit a compact, low-pressure, low-maintenance air supply.
