Airtac GAFR Adjustable Filter Regulator GAFR30015SK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SK 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.

About the Airtac GAFR Adjustable Filter Regulator GAFR30015SK
The GAFR30015SK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. It handles a 1/2in port with a working range of 0.15-0.9 MPa (20-130 psi) and uses a 40 um element.
This 500 g unit features a diversion structure that spins air to separate liquid water and solid particles into its 60 cc drain bowl. The balanced, self-locking regulator holds the outlet steady as supply pressure varies, and the circular gauge with MPa/psi scale is fitted.

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.

Where the Airtac GAFR Adjustable Filter Regulator GAFR30015SK Is Used
Precision Jig Fixtures
Feed a single precision jig or clamping fixture on an assembly bench, where the 40 um element protects sensitive locating pins and the steady regulated pressure keeps clamping force consistent.
Small Machine Headers
Supply a compact machine header serving two or three pneumatic cylinders, using the 1/2in port to distribute air at a stable 0.15-0.9 MPa while the 60 cc bowl captures condensate between shifts.
Packaging Line Actuators
Power indexing stops or light pusher cylinders on a packaging line, where the semi-auto drain lets operators purge the bowl during changeovers and the self-locking knob resists drift from line vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SK the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in port applications where the 3500 L/min flow envelope (plotted at 0.7 MPa inlet) suits medium-sized actuators or small machine headers. The PC bowl is the standard build choice, while the semi-auto and manual drains are both fitted for flexible condensate removal. The included mounting bracket simplifies panel installation, and the 40 um element handles general workshop air. The PT thread provides the MPa/psi gauge scale, and the reverse-flow (reflux) valve is fitted as an ordering difference. If downstream lubrication is needed, order the matching GAFC300-15 combination instead. Remember that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 g unit on its bracket, not on the tubing.
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.
Airtac GAFR Adjustable Filter Regulator GAFR30015SK FAQ
The GAFR30015SK is a filter & regulator with a 1/2in port, pressure 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, 60 cc drain bowl, and 500 g weight. It has a 40 um element, semi-auto and manual drains, a fitted gauge, and a reverse-flow valve.
The K indicates a reverse-flow (reflux) valve is attached. It is an ordering difference from the standard GAFR30015S; the catalogue defers its detailed function to a separate page. If you need lubrication downstream, this unit does not provide it - order the GAFC300-15 combination instead.
