Airtac GAFR Adjustable Filter Regulator GAFR30010LJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LJWK 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 3/8" 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 GAFR30010LJWK
The GAFR30010LJWK is a filter & regulator in a single body, combining a diversion filter with a balanced pressure regulator. It handles 3/8in ports and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi), with a 5 um element for finer filtration. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet steady as supply pressure varies.
This unit weighs 500 g and has a 60 cc condensate bowl, making it a compact choice for tight panels. The semi-auto and manual drains are both fitted, and the PT thread carries a MPa/psi gauge scale. A reverse-flow (reflux) valve is attached as an ordering difference, and no bracket is included for direct panel mounting.

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 GAFR30010LJWK Is Used
Precision valve control
Feed a precision pneumatic valve that requires a stable, low supply pressure. The 5 um element traps fine particles, and the balanced regulator holds the setpoint as line pressure fluctuates.
Lab air bench
Supply a laboratory air bench where instruments need clean, low-pressure air. The 60 cc bowl handles condensate from a typical day, and the manual drain lets you purge on a schedule.
Compact jig station
Power a small assembly jig with a single actuator. The 500 g body mounts directly to a panel without a bracket, saving rail space in a tight workcell.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010LJWK the Right Air-Prep Unit?
Choose the GAFR30010LJWK when you need a lower regulated output capped at 0.4 MPa and a 5 um element for sensitive equipment. The PC bowl suits standard shop air, while the semi-auto plus manual drain gives you both automatic purging and a manual override. The missing bracket (J) means you plan to mount it on a panel or existing frame, and the fitted gauge reads in MPa/psi via the PT thread. If oil is needed downstream, order the matching GAFC300-10 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 (3/8" 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30010LJWK FAQ
The GAFR30010LJWK is a filter & regulator with a 3/8in port, a working pressure range of 0.15-0.4 MPa (20-58 psi), a max 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 60 cc drain bowl, and weighs 500 g. The 5 um element and semi-auto plus manual drains are standard on this model.
The L code sets the lower pressure range (0.15-0.4 MPa) for applications that must not exceed 0.4 MPa. The K code adds a reverse-flow (reflux) valve as an ordering difference; its function is detailed in the catalogue. This model also omits the bracket (J) for panel mounting.
