Airtac GAFR Adjustable Filter Regulator GAFR30015ASJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ASJ 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 GAFR30015ASJ
The GAFR30015ASJ is a filter & regulator from AirTAC, combining both functions in a single body. It cleans incoming air with a diversion structure that spins out liquid water and solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator. This model uses a 1/2in port, a 40 um element, and a PC bowl, with a working range of 0.15-0.9 MPa (20-130 psi).
This unit weighs 500 g and has a 60 cc condensate bowl, which is the sole bowl on the device. Because the filter and regulator share one housing, it replaces a separate GAF filter plus GAR regulator, reducing potential leak points and saving rail space. The circular gauge with MPa/psi scale is fitted, and the automatic drain handles condensate without manual intervention.

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 GAFR30015ASJ Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station. The 1/2in port delivers adequate flow, while the automatic drain keeps the 60 cc bowl from filling during long shifts.
Machine tool air supply
Supply clean, regulated air to a lathe or milling machine's work-holding fixtures. The 500 g body mounts securely to a machine frame, and the gauge allows quick pressure verification.
Automated test rig
Power a test rig that cycles actuators repeatedly. The balanced regulator holds the set pressure as supply varies, and the automatic drain removes condensate without stopping production.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ASJ the Right Air-Prep Unit?
Choose the GAFR300 body for 1/2in port applications needing a 60 cc drain bowl and a flow envelope plotted to 3500 L/min at 0.7 MPa inlet. The PC bowl suits general-purpose use; select the C or N bowl option for different build preferences. The automatic drain (A) is ideal for unattended or wet lines, while the blank drain option provides both semi-auto and manual drains. This model has no bracket (J), so plan for panel mounting or an existing bracket. The standard pressure type (S) covers 0.15-0.9 MPa; the L type tops out at 0.4 MPa. A 40 um element is fitted; the W option upgrades to 5 um for finer filtration. The PT thread sets the gauge scale to MPa/psi. If oil is needed downstream, order the matching GAFC300-15 combination. 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 GAFR30015ASJ FAQ
The GAFR30015ASJ is a filter & regulator with a 1/2in port, a working pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C and must not freeze. The drain bowl holds 60 cc, and the unit weighs 500 g.
The J code in GAFR30015ASJ means the mounting bracket is omitted. This is for installations where the unit is panel-mounted or secured with an existing bracket. If a bracket is required, order the version without the J code, which includes it.
