The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LNWK 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.
The GAFR30010LNWK is a filter and regulator combined into one body, so it cleans incoming air and sets a steady outlet pressure without needing separate units. This model uses a 3/8in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 5 um element that traps finer particles for sensitive equipment.
The unit weighs 500 g and includes a 60 cc condensate bowl, which collects the water and solids separated by the internal diversion structure. A reverse-flow (reflux) valve is fitted, and the mounting bracket is included, making it ready for panel installation.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR300 is 1/8" if you add one. 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 5 um filtered, regulated air supply to a precision pneumatic valve that needs stable low pressure for consistent actuation.
Supply clean, low-pressure air to a laboratory instrument or test rig where fine filtration and a 0.4 MPa ceiling protect sensitive components.
Mount this unit on a small assembly jig or single actuator station, using the included bracket for a secure, space-saving installation.
Choose the GAFR30010LNWK when your circuit needs a compact filter-regulator with a 3/8in port and a lower-pressure ceiling of 0.4 MPa. The 5 um element suits precision valves or instrument air, while the semi-auto plus manual drain gives you both automatic purging and a manual override. The PC bowl is the standard build, and the included bracket simplifies mounting; if you need a gauge later, the 1/8in connection is ready for one. For lines that require lubrication 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 regulated top, which is useful for maintaining stable output even if inlet pressure fluctuates.
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 GAFR30010LNWK is a filter & regulator with a 3/8in port, a lower-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 operating temperature range is -5 to 70 C. It has a 60 cc drain bowl, weighs 500 g, and comes with a 5 um element and a semi-auto plus manual drain.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFR30010LNWK. This is an ordering difference from models without the K code; the valve is drawn as a separate pneumatic symbol in the catalogue. Its specific function is detailed on a page not included in our data, so we recommend confirming the operational details from the full AirTAC datasheet.
