Airtac GAFR Adjustable Filter Regulator GAFR200N08LJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08LJ 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 GAFR200N08LJ
The GAFR200N08LJ is a filter and regulator combined in a single body, saving space on a compact machine frame. It handles 1/4in ports and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi) with a 40 um element. The nylon bowl collects condensate and solid particles separated by the internal diversion structure, which spins the airflow to drop out liquid water and debris.
This 290 g unit is the smallest in the GAFR series, with a 25 cc drain bowl that requires more frequent checking than larger bodies. The pressed-in self-locking knob holds the set pressure steady against vibration, and the circular gauge with MPa/psi scale is fitted for direct reading. No bracket is included, so plan for panel mounting or an existing support structure.

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 GAFR200N08LJ Is Used
Single Jig Clamping
Feed a small bench-mounted jig or fixture that needs clean, regulated air at a modest pressure. The 1/4in port and 25 cc bowl match the low air volume of a single clamping cylinder.
Bench Pneumatics
Power a small air tool or a manual test rig where space is tight. The compact 290 g body and nylon bowl fit into a crowded workbench layout without adding bulk.
Prototype Station
Supply a lab or R&D setup that requires a stable, low-pressure air source. The self-locking regulator holds the setpoint against minor line fluctuations during experiments.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08LJ the Right Air-Prep Unit?
Choose the GAFR200 body for light-duty circuits with 1/4in piping and low air consumption, such as a single jig or small actuator. The nylon bowl (N) is a build choice, but confirm compatibility with any aggressive chemicals in the environment. The blank drain code means both semi-auto and manual drains are fitted, giving you a backup if the automatic mechanism is not desired. The L type caps the regulated output at 0.4 MPa, so verify the downstream equipment never needs more than that. The J code omits the mounting bracket, which suits panel-mount installations or retrofit onto existing hardware. The 40 um element is the standard grade, adequate for general shop air. The PT thread means the gauge reads in MPa/psi, matching most local pressure gauges. If oil is needed downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 GAFR200N08LJ FAQ
The GAFR200N08LJ is a filter & regulator with a 1/4in port, working pressure range of 0.15-0.4 MPa (20-58 psi), and a maximum pressure of 1.0 MPa (145 psi). Proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. It has a 25 cc drain bowl and weighs 290 g.
The L code sets the regulated output to a maximum of 0.4 MPa, which is suitable for delicate equipment that must not see higher pressures. The J code means the mounting bracket is omitted, so you must provide your own panel mount or support. The nylon bowl is a material choice, but the pressure and temperature ratings are identical to PC or metal bowls.
