The AirTAC Airtac GAFR Filter & Regulators GAFR30015ST 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 GAFR30015ST pairs an air filter and a pressure regulator inside a single 1/2in-port body, so one component cleans the supply and then locks in your working pressure. There is no lubricator stage and no oil bowl: the only bowl on this unit catches condensate. One body in place of a separate filter and regulator means fewer joints to seal and a shorter prep stack on the rail. As a Standard (S) type it sets outlet pressure anywhere from 0.15 to 0.9 MPa (20-130 psi). The 40 um element spins the flow so liquid water and solid particles drop into the 60 cc drain bowl before air reaches the regulator. A mounting bracket, a circular gauge with clip and magnifier, and NPT threads with a psi/bar gauge scale are all fitted as standard.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in psi / bar, set by the NPT 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.

A carton sealer or wrapping station drawing moderate flow gets clean, steady air at its 1/2in connection, with the 60 cc bowl catching condensate between shifts.
Feed a machining cell's clamps or actuators from a single prep point; the bracket fixes the 500 g unit to the frame rather than leaving it carried by the tubing.
Branch feeds along a sorting or assembly conveyor stay within the 3500 L/min flow envelope of this 300 body at 0.7 MPa inlet, with the fitted gauge letting staff verify set pressure at a glance.
The 300 body with a 1/2in port suits machines drawing more than a 1/4in GAFR200 can feed but less than the 7000 L/min envelope of the larger GAFR400. Bowl options across the code are PC (blank), metal (C) or nylon (N); all three share the same 1.0 MPa (145 psi) maximum and -5 to 70 C rating, so treat material as a build choice and confirm suitability for aggressive surroundings. The blank drain position includes both a semi-auto and a manual drain; choose the A suffix if you want automatic draining on an unattended line. Adding J drops the included bracket for panel-mounted builds, and N removes the gauge (1/8in connection if you add one later). W steps filtering down to 5 um for finer protection of downstream valves, and K attaches a reverse-flow (reflux) valve as an ordering difference. This ST build keeps the gauge, keeps the bracket, and uses NPT threads, so match your piping and the psi/bar gauge scale your operators read. If the circuit also needs oil downstream, order the matching GAFC300 combination instead, since no GAFR adds lubricant. As a margin note, proof pressure of 1.5 MPa (215 psi) over the 1.0 MPa (145 psi) maximum is a 1.5x burst-test margin, which is safety headroom and not a licence to operate above 1.0 MPa.
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.
Outlet pressure is adjustable from 0.15 to 0.9 MPa (20-130 psi) on this Standard type. Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). The rated temperature range is -5 to 70 C and the unit must not freeze. The condensate bowl capacity is 60 cc and the weight is 500 g. The element grade is 40 um and the port is 1/2in NPT.
The T code switches the port and gauge threads to NPT and sets the supplied circular gauge to a psi/bar scale. A plain GAFR30015 (no T) uses PT threads with an MPa/psi gauge, and a G suffix gives G threads with a bar/MPa scale, so pick the thread family and gauge scale that match the rest of your installation.
