Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJ 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 40 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 GAFR200N08ALJ
The GAFR200N08ALJ is a filter and regulator combined into a single body, so it cleans the air and stabilizes outlet pressure without needing a separate filter plus regulator pair. This unit has a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 40 um element; it carries no lubricator and has only one bowl, the 25 cc condensate bowl.
Its nylon bowl and automatic drain make it a low-maintenance choice for compact machines where the 290 g weight suits a small panel or frame mount. The balanced regulator holds the set pressure as supply varies, and the pressed-in knob resists drift from vibration, so the outlet stays steady even on equipment that shakes.

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 GAFC200-08 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 GAFR200N08ALJ Is Used
Compact jig or fixture
Feed a single pneumatic clamp or small indexing fixture on an assembly bench. The 1/4in port and 290 g body fit tight spaces, and the automatic drain clears condensate without an operator.
Lab air supply
Supply a test rig or small instrument that needs a stable but modest pressure. The lower 0.4 MPa ceiling suits delicate setups, and the 40 um element protects the downstream valve.
Maintenance cart
Mount on a portable service cart to provide filtered, regulated air to hand tools or a blow gun. The nylon bowl resists knocks better than PC in a workshop environment.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJ the Right Air-Prep Unit?
Choose this GAFR200 when your line is 1/4in and the machine needs only up to 0.4 MPa; the L type tops out there, so if you may ever need more, pick the S version instead. The nylon bowl is a build choice with the same 1.0 MPa max and -5 to 70 C rating as PC or metal, so confirm compatibility for aggressive surroundings. This model has the automatic drain, no bracket (J), a fitted gauge with MPa/psi scale, and a 40 um element; the K option would add a reverse-flow valve, and the W option would swap to 5 um filtration. If oil is needed downstream, order the matching GAFC200-08 combination rather than expecting this unit to lubricate. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this regulator's 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 GAFR200N08ALJ FAQ
Working pressure is 0.15-0.4 MPa (20-58 psi); max pressure is 1.0 MPa (145 psi); proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C and the unit must not freeze. The drain bowl holds 25 cc and the total weight is 290 g.
The L code sets a 0.15-0.4 MPa range for applications that never need more than 58 psi. The J code omits the mounting bracket, so you supply your own panel mount or existing bracket; the gauge is still fitted and reads MPa/psi.
