Airtac GAFR Adjustable Filter Regulator GAFR40015ASW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASW 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 5 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 GAFR40015ASW
The GAFR40015ASW is a filter & regulator that combines air filtration and pressure regulation in a single body, eliminating the need for separate units. It handles a 1/2in port with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and uses a 5 um element for fine particle removal.
This 880 g unit features a 100 cc condensate bowl and an automatic drain, making it suitable for applications where regular manual draining is impractical. The integrated circular gauge with MPa/psi scale allows for direct pressure monitoring, while the balanced regulator mechanism helps maintain a stable outlet pressure as supply varies.

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 GAFR40015ASW Is Used
Precision machining centers
Feed a consistent 0.15-0.9 MPa supply to CNC tool changers or precision pneumatic actuators where the 5 um element protects sensitive valves from fine wear particles.
Assembly line automation
Supply filtered air to multi-station assembly fixtures on a 1/2in line, with the automatic drain handling condensate without operator intervention during long production runs.
Instrument air for test rigs
Provide cleaner air to laboratory pneumatic test equipment or gauging systems, where the 5 um filtration grade helps maintain consistent performance of sensitive components.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASW the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 1/2in port and a flow envelope plotted to 7000 L/min at 0.7 MPa inlet. The PC bowl is the standard choice, while the automatic drain suits wet or unattended lines. The 5 um element traps finer particles than the standard 40 um, ideal for precision equipment but requiring more frequent service. The included mounting bracket simplifies installation, and the PT thread with MPa/psi gauge scale matches common regional standards. If oil is needed downstream, order the matching GAFC400-15 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 880 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 GAFC400-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40015ASW FAQ
The GAFR40015ASW is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.9 MPa (20-130 psi), maximum pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g. The unit includes a 5 um element and an automatic drain.
The automatic drain expels condensate from the 100 cc bowl without manual intervention, making it suitable for unattended operation or lines with high moisture content. This contrasts with the semi-auto+manual drain option, which requires periodic manual opening to release accumulated water.
