The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LWK 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 GAFR30010LWK is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. This 3/8in model handles a lower pressure band of 0.15-0.4 MPa (20-58 psi) and comes with a 5 um element for finer filtration.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 60 cc drain bowl. The balanced regulator mechanism holds the set outlet pressure steady as supply pressure varies, and the pressed-in self-locking knob resists drift from vibration.

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 clamping fixture or a small indexing table where a steady 0.15-0.4 MPa supply protects delicate workholding from pressure spikes.
Supply instrument air to a laboratory test bench or analytical equipment where the 5 um element removes fine particulates that could clog small orifices.
Power a handheld screwdriver or a small pneumatic press on a light assembly station, where the lower pressure range prevents over-forcing small fasteners.
Choose this GAFR300 body for 3/8in porting with a 500 g mass, a step up from the GAFR200's 290 g frame. The 5 um element traps finer particles than the standard 40 um for sensitive downstream valves, though it will require more frequent servicing. The semi-auto and manual drains are both fitted, letting you choose between automatic purging or manual control. The included mounting bracket simplifies installation, and the fitted circular gauge with MPa/psi scale shows the set pressure directly. The reverse-flow (reflux) valve is attached as an ordering difference. If your line needs oil downstream, order the matching GAFC300-10 combination instead. Note that 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.
This filter & regulator has a 3/8in port, a working 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 in temperatures from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g.
The K indicates a reverse-flow (reflux) valve is fitted to the unit. This is an ordering difference from a standard GAFR300; the specific function is detailed in the catalogue pages not included in our data.
