The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C10SNW 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.
The GAFR300C10SNW is a filter and pressure regulator combined into one body, so a single unit both cleans the air and holds a steady outlet pressure. This 3/8in version has a metal bowl, a 5 um element, and a working range of 0.15-0.9 MPa (20-130 psi).
The diversion structure spins the incoming air to separate liquid water and solid particles into the 60 cc condensate bowl, while the balanced regulator keeps the set pressure stable as supply varies. The pressed-in self-locking knob resists drift from vibration, and the unit weighs 500 g, so it needs a proper panel or frame mount rather than support from the tubing.

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 supply to precision pneumatic valves on a small assembly station, where fine particles could otherwise cause sticking or premature wear.
Protect one air cylinder or rotary actuator on a dedicated line, using the 3/8in port to match the actuator's flow demand without oversizing the filter.
Mount inside a machine tool electrical cabinet to supply clean, regulated air to solenoid valves and sensors, with the metal bowl suited to a shop-floor environment.
Choose the GAFR300 size class for 1/4in to 1/2in port lines; this 3/8in model sits between the smaller GAFR200 and the larger GAFR400, whose flow envelope is plotted to 7000 L/min at 0.7 MPa inlet. The metal bowl is a build choice for the environment, and the 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. This unit ships with the mounting bracket and a semi-auto plus manual drain; the A code would replace that with an automatic drain, and the J code would omit the bracket. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The PT thread gives an MPa/psi gauge scale; G and NPT are available. If oil is needed downstream, order the matching GAFC300-10 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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.
The GAFR300C10SNW is a filter & regulator with a 3/8in port, a 5 um element, and a metal bowl. The pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, the drain bowl holds 60 cc, and the unit weighs 500 g.
The N code after the port means no gauge is supplied, so the set pressure cannot be read without adding one. The gauge connection on the GAFR300 body is 1/8in, so a standard 1/8in gauge can be fitted later if needed.
