The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LJK 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.
The GAFR30010LJK is a filter and pressure regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate components. This 3/8in unit operates in the lower 0.15-0.4 MPa (20-58 psi) band and uses a 40 um element to trap solids and liquid water.
A balanced regulator mechanism keeps the outlet steady as supply pressure varies, while the pressed-in self-locking knob resists drift from vibration. The 60 cc condensate bowl collects what the diversion structure spins out, and the included circular gauge with MPa/psi scale lets you read the set pressure directly.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. This unit filters and regulates only; it does not add lubrication.

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.

Feed a single precision pneumatic valve or small actuator that requires a stable, lower regulated pressure without the risk of over-pressurizing sensitive components.
Use on a lab or workbench test setup where a compact 3/8in unit with a 40 um filter protects instruments and the lower pressure range suits delicate calibration work.
Mount on a light assembly fixture where the 500 g body and included gauge allow operators to verify set pressure, while the semi-auto drain suits regular maintenance schedules.
Choose the GAFR300 body for 3/8in ports with a 500 g mass and a flow curve plotted to 3500 L/min at 0.7 MPa inlet, a step up from the GAFR200's 2000 L/min envelope. This model has a PC bowl, a semi-auto drain plus manual drain, a 40 um element, and no mounting bracket (J), so plan for panel mounting or an existing bracket. The PT thread means the gauge reads MPa/psi, and the K code adds a reverse-flow valve as an ordering difference. If the line needs oil 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
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.
The GAFR30010LJK is a filter & regulator with a 3/8in port, 0.15-0.4 MPa (20-58 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, and -5 to 70 C temperature range. It has a 60 cc drain bowl, weighs 500 g, uses a 40 um element, and includes a circular gauge with MPa/psi scale.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFR30010LJK. It is an ordering difference from models without the K code, and its function is detailed in the catalogue page not included in our data. The unit still filters and regulates in one body without any lubricator.
