Airtac GAFR Adjustable Filter Regulator GAFR30010ALJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ALJK 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 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 GAFR30010ALJK
The GAFR30010ALJK is a filter and regulator combined into a single body, eliminating the need for separate GAF filter and GAR regulator units. This 3/8in port model handles a lower pressure band of 0.15-0.4 MPa (20-58 psi) and comes with a 40 um element to trap solid particles.
Its diversion structure spins incoming air to separate liquid water and solids into the 60 cc drain bowl, while the balanced regulator maintains a steady outlet. The pressed-in self-locking knob resists set-pressure drift from vibration, and the unit weighs 500 g, fitting neatly into compact machine builds.

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 GAFC300-10 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 GAFR30010ALJK Is Used
Precision pressure setting
Set a stable 0.2 MPa for a delicate pneumatic sensor circuit, knowing the balanced regulator holds the outlet as shop pressure fluctuates.
Compact machine build
Mount this 500 g unit on a small assembly fixture where a separate filter and regulator would not fit, saving rail space and sealing points.
Laboratory air supply
Feed a test rig with filtered air at a controlled low pressure, using the automatic drain to handle condensate without manual attention.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010ALJK the Right Air-Prep Unit?
Choose the GAFR300 body when you need 3/8in ports and a 500 g footprint; step up to the GAFR400 (100 cc bowl, 880 g) for higher flow demands, or down to the GAFR200 (25 cc bowl, 290 g) for smaller jigs. This model has a PC bowl, an automatic drain for wet lines, and no mounting bracket (J), so plan for panel mounting or an existing bracket. The 40 um element suits general shop air, while the lower-pressure (L) type caps at 0.4 MPa, making it ideal for delicate circuits but wrong if you might need more. A circular gauge with MPa/psi scale is fitted, and the reverse-flow (reflux) valve is attached as an ordering difference. If oil is needed downstream, order the matching GAFC300-10 combination instead. 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 (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 GAFR30010ALJK FAQ
Working pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The L type is set for a 0.15-0.4 MPa band, suitable for applications that must not exceed 0.4 MPa. The K code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference from standard models.
