Airtac GAFR Adjustable Filter Regulator GAFR30015AS
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015AS 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 GAFR30015AS
The GAFR30015AS is a filter and regulator combined in one body, so it cleans incoming air and sets a steady outlet pressure without needing separate units. This 1/2in version handles flows plotted to 3500 L/min at 0.7 MPa inlet, weighs 500 g, and works in the 0.15-0.9 MPa (20-130 psi) range with a 40 um element.
The automatic drain clears condensate without manual attention, and the circular gauge with MPa/psi scale is fitted. Its 60 cc bowl collects water and solids spun out by the diversion structure, and the balanced regulator holds the set pressure as supply varies.

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 GAFR30015AS Is Used
Machine tool air prep
Feed a CNC lathe or milling machine's pneumatic actuation with clean, regulated air at 0.15-0.9 MPa, while the automatic drain handles condensate from high-cycling solenoids.
Assembly line branch
Supply a 1/2in branch feeding multiple workstations, where the 60 cc bowl and 500 g body fit neatly into a panel and the gauge lets operators verify set pressure at a glance.
Test rig air supply
Provide stable pressure to a pneumatic test fixture or calibration bench, where the balanced regulator minimizes drift and the 40 um element protects sensitive valves from particulates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015AS the Right Air-Prep Unit?
Choose the GAFR300 body for medium-flow lines; its 1/2in port suits branch feeds, while the GAFR400 above offers 100 cc bowl and 7000 L/min envelope if you need more capacity. The PC bowl is the standard build, the automatic drain suits wet or unattended lines, and the included bracket simplifies mounting. The 40 um element handles general shop air, and the PT thread gives an MPa/psi gauge scale. If oil is needed downstream, order the matching GAFC300-15 combination instead. Max supply 1.0 MPa 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 GAFR30015AS FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The drain bowl holds 60 cc, the unit weighs 500 g, and the flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The A code means an automatic drain that expels condensate without manual operation, ideal for wet or unattended lines. This contrasts with the blank drain option, which ships both semi-auto and manual drains for operator-controlled purging.
