The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015S 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 40 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 GAFR30015S is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate components. This 1/2in port model works across 0.15-0.9 MPa (20-130 psi) and uses a 40 um element to trap solid particles and spun-out liquid water.
Its 500 g mass and 60 cc condensate bowl place it in the mid-size class, where the included mounting bracket should support the unit rather than the tubing. The balanced regulator mechanism holds the set pressure as supply 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 GAFC300-15 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 single machining center's pneumatic controls with filtered, regulated air at a stable pressure, using the 1/2in port to match medium-flow tooling lines.
Supply a bank of small cylinders on an assembly conveyor, where the 60 cc bowl handles normal condensate between scheduled line maintenance.
Provide clean, regulated air to a laboratory test jig or prototype station, relying on the gauge to verify set pressure and the self-locking knob to hold it.
Choose this GAFR300 body when you need a 1/2in port with a 60 cc drain bowl, stepping up from the GAFR200's 25 cc bowl when condensate volume is higher. The PC bowl suits general industrial use, while the semi-auto and manual drains are both fitted for flexible servicing. The standard S type covers 0.15-0.9 MPa, the bracket is included, and the fitted circular gauge reads in MPa/psi. A 5 um element (W) is available for finer filtration, and the K option adds a reverse-flow valve. If oil is needed downstream, order the matching GAFC300-15 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated 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.
The GAFR30015S is a filter and regulator with a 1/2in port, working range 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 60 cc drain bowl, and 500 g weight.
The GAFR30015S combines both filtering and pressure regulation in one body, replacing the need for separate GAF and GAR units. It has one condensate bowl and does not include any lubrication function.
