The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASNW 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 1/4" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.
The GAFR30008ASNW is a filter and pressure regulator combined in a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/4in port with a 5 um element and an automatic drain, rated for 0.15-0.9 MPa (20-130 psi).
This 500 g unit uses a diversion structure to spin out liquid water and solid particles into its 60 cc condensate bowl. The balanced, self-locking regulator keeps the outlet pressure steady as supply varies, and the pressed-in knob resists drift from vibration.

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 GAFC300-08 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 bank of precision pneumatic valves on a small assembly machine. The 5 um element protects fine internal passages from abrasive particles, while the balanced regulator holds a steady setpoint for consistent actuation.
Supply a laboratory instrument or analyzer that needs clean, regulated air. The fine 5 um filtration removes solid contaminants, and the automatic drain keeps the 60 cc bowl from filling during long, unattended runs.
Protect a single pneumatic cylinder or actuator on a dedicated work cell. This compact unit filters and regulates the air right at the point of use, with the included bracket mounting securely to the machine frame.
Choose this GAFR300 for 1/4in lines needing filtration and regulation in one compact package. The 5 um element traps finer particles than the standard 40 um, making it suitable for precision valves or instrument air, though it will need more frequent service. The automatic drain handles condensate without manual intervention, ideal for wet or unattended lines. The mounting bracket is included, and the PT thread uses an MPa/psi gauge scale. If you need lubrication downstream, order the matching GAFC300-08 combination instead. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan for a supply near 1.0 MPa to achieve the highest setpoints.
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 GAFC300-08 combination; do not expect an oil mist from this unit.
This filter & regulator has a 1/4in port, a working pressure range of 0.15-0.9 MPa (20-130 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, has a 60 cc drain bowl, and weighs 500 g. The element is 5 um and the drain is automatic.
The 'N' in the code GAFR30008ASNW indicates no gauge is supplied. The gauge connection on the GAFR300 body is 1/8in, so you can add a compatible gauge later if you need to read the outlet pressure. Without one, the set pressure cannot be visually verified.
