Airtac GAFR Adjustable Filter Regulator GAFR20008LJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008LJ 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 GAFR20008LJ
The GAFR20008LJ is a compact filter & regulator from AirTAC, combining particle filtration and pressure control in a single body. It handles 1/4in ports with a lower-pressure range of 0.15-0.4 MPa (20-58 psi) and a 40 um element.
This unit weighs just 290 g and has a 25 cc condensate bowl. Its diversion structure spins incoming air to separate liquid water and solid particles before regulation. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet steady.

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 GAFR20008LJ Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a benchtop assembly fixture. The 1/4in port and 290 g body suit low-flow, space-constrained setups where stable low pressure prevents part distortion.
Bench-top Pneumatic Press
Supply a small arbor press with regulated air at 0.15-0.4 MPa. The 25 cc bowl handles light condensate from intermittent use, and the manual drain gives quick service access.
Laboratory Air Supply
Protect a sensitive lab valve or instrument with filtered, low-pressure air. The 40 um element traps particles, while the lower pressure range suits delicate test rigs.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008LJ the Right Air-Prep Unit?
Choose the GAFR200 for small jigs or single actuators where space is tight. This model has no mounting bracket (J code), so plan for panel mounting or an existing bracket. The semi-auto drain plus manual drain gives you both options for condensate removal. The gauge is fitted with an MPa/psi scale, matching the PT thread. The lower-pressure type tops out at 0.4 MPa, so if your machine may ever need more, select the standard S type instead. For oil downstream, order the matching GAFC200-08 combination. 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa 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 GAFR20008LJ FAQ
Working pressure is 0.15-0.4 MPa (20-58 psi). Maximum 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 and the unit weighs 290 g.
The J code omits the mounting bracket. This suits panel-mount installations or setups where you already have a bracket. If you need the included bracket, order without the J code.
