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 is a combined air filter and pressure regulator built into a single 1/2in ported body. Incoming air is spun through a diversion stage so condensate and solid particles fall into the 60 cc drain bowl, then a balanced regulator sets a steady outlet anywhere from 0.15 to 0.9 MPa (20-130 psi). Because both jobs happen in one casting, it takes the place of a separate filter and a separate regulator and saves the panel width those two units would need.
This standard-type unit carries a 40 um element, a circular pressure gauge on an NPT connection reading in psi and bar, and ships with both semi-automatic and manual draining of the condensate bowl plus a mounting bracket for frame or panel fixing. The pressed-in self-locking knob holds the setpoint against vibration, and the body weighs about 500 g, so mount it rather than letting the tubing carry it. Rated from -5 to 70 C and it must not freeze. If your circuit also needs oil mist downstream, order the GAFC300-15 combination instead, since a GAFR never lubricates.

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 1/2in feed feeding wrapper sealing cylinders and clamp actuators, with the regulator holding a repeatable pressure band from 0.15 to 0.9 MPa (20-130 psi) shift after shift.
Fixture clamps on a machining cell need clean, steady air; the spun separation stage drops water and chips into the 60 cc bowl before they reach the valves.
A header drop serving screwdrivers and small actuators at one bench, bracket-mounted to the frame so the 500 g unit is not hanging on its tubing.
Choose this code when a 1/2in NPT line needs filtration and regulation from one unit: body 300 gives you a 60 cc drain bowl and a flow curve plotted to 3500 L/min at 0.7 MPa inlet. Step up to GAFR400 (1/2in or 3/8in, curve plotted to 7000 L/min at 0.7 MPa inlet, 100 cc bowl) if condensate volume or air demand outgrows this body, or down to GAFR200 with 1/8in or 1/4in ports for lighter circuits. The blank bowl code here is polycarbonate; metal (C) and nylon (N) bowls are orderable on this body, and all three share the same 1.0 MPa (145 psi) maximum, so pick by environment and confirm compatibility where conditions are aggressive. Drain is semi-automatic plus manual as ordered; an automatic drain is available if nobody will be at the machine. Keep the standard 0.15-0.9 MPa (20-130 psi) band unless your circuit never exceeds 0.4 MPa (20-58 psi), in which case an L-type variant exists for this body. The 40 um element suits general shop air; a W-code 5 um element is the option for finer protection. With NPT ports the fitted gauge reads psi and bar, matching US-style panels. Oil is never added by this unit; for that, the GAFC300-15 combination is the matching upgrade.
Plan your compressor side carefully: 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so a feed near the maximum is needed if you intend to set 0.9 MPa at the outlet.
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.
Working range is 0.15-0.9 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). Temperature rating is -5 to 70 C and the unit must not freeze. The single condensate bowl holds 60 cc, the element grade is 40 um, the port is 1/2in NPT, and the unit weighs about 500 g with the gauge and bracket fitted.
The GAFR30015ST filters the air and regulates pressure in one body but adds no oil of any kind; it has only the condensate bowl and no lubricator. If your actuators or valves need a oil mist supply downstream, order the GAFC300-15 combination, which keeps the same 300 body and 1/2in port and adds a lubricator to the set.
