The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ALJNWK 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 GAFR30010ALJNWK is a filter and pressure regulator combined into a single body, so incoming air is first spun to separate liquid water and solid particles, then regulated to a steady outlet pressure. This lower-pressure version operates from 0.15 to 0.4 MPa (20-58 psi) and comes with a 5 um element for finer filtration, plus an automatic drain that clears the 60 cc condensate bowl without manual attention.
This 500 g unit with a 3/8in port replaces the need for separate filter and regulator bodies, reducing potential leak points and saving space on the rail. The pressed-in self-locking knob resists set-pressure drift from vibration, while the balanced mechanism holds the outlet steady as supply pressure varies, making it suitable for applications where consistent low pressure is critical.

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 precision regulator or a sensitive pilot valve on a machine tool with clean, low-pressure air. The 5 um element protects fine orifices from particles that would clog them, while the automatic drain keeps the 60 cc bowl from flooding during long production runs.
Supply a lab bench or test fixture that requires a stable, low-pressure air source. The balanced regulator holds the outlet steady as the shop supply fluctuates, and the self-locking knob keeps the setpoint from drifting when nearby equipment vibrates.
Mount this 500 g unit on a small panel or frame to condition air for a single actuator or a small jig. Because the filter and regulator share one body, you save rail width and reduce the number of threaded joints that could leak compared to separate units.
Choose the GAFR30010ALJNWK when you need a compact filter-regulator with a 3/8in port and a lower 0.15-0.4 MPa (20-58 psi) output range. The 5 um element traps finer particles than the standard 40 um grade, making it suitable for precision valves or instrument air, though it will require more frequent element service. The automatic drain (A) handles condensate removal in unattended or wet lines, while the absence of a bracket (J) suits panel-mount installations, and the missing gauge (N) means you must add one via the 1/8in gauge connection to read set pressure. The reverse-flow (reflux) valve (K) is fitted as an ordering difference, and the PT thread carries the MPa/psi gauge scale. If your line needs 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 top of this unit's regulated band.
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 GAFR30010ALJNWK is a filter & regulator with a 3/8in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc, the unit weighs 500 g, and the gauge connection is 1/8in if a gauge is added later. It comes with a 5 um element and an automatic drain.
The J code means the mounting bracket is not included, so you must plan to panel-mount the unit or use an existing bracket. The N code means no gauge is supplied, so you cannot read the set pressure directly; you would need to add a gauge to the 1/8in connection to monitor outlet pressure. Both choices reduce the initial part count but require additional components for those functions.
