The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015LW 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 1/2" 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 GAFR30015LW is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port with a lower pressure range of 0.15-0.4 MPa (20-58 psi) and uses a fine 5 um element.
This model includes a circular gauge with an MPa/psi scale and a mounting bracket. Its 60 cc condensate bowl and 500 g weight define its size class, making it suitable for applications requiring precise, low-pressure regulation.

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 GAFC300-15 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 precise low-pressure air supply to a spray gun or coating system where consistent, gentle application is critical.
Provide filtered, low-pressure air to laboratory pneumatic controls or instruments that require a stable 0.15-0.4 MPa input.
Power a small, air-driven screwdriver or tightening fixture on an assembly bench with a clean, regulated supply.
Choose this GAFR300 for 1/2in piping where a lower outlet pressure of 0.15-0.4 MPa (20-58 psi) is sufficient. The 5 um element traps finer particles than the standard 40 um, which is beneficial for sensitive equipment but will require more frequent servicing. This unit comes with the mounting bracket and a gauge; the semi-auto and manual drains are both fitted. If your system needs oil downstream, order the matching GAFC300-15 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 GAFC300-15 combination; do not expect an oil mist from this unit.
This filter & regulator has a 1/2in port, a pressure range of 0.15-0.4 MPa (20-58 psi), a max 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 'L' designates the lower-pressure type, which has a maximum regulated output of 0.4 MPa (58 psi) instead of the standard 0.9 MPa (130 psi). This makes it suitable for applications with sensitive components that must not see higher pressures.
