Airtac GAFR Adjustable Filter Regulator GAFR40015AS
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015AS 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 GAFR40015AS
The GAFR40015AS is a filter and regulator combined into a single body, handling both air purification and pressure control in one compact unit. It serves a 1/2in port line with a working range of 0.15-0.9 MPa (20-130 psi) and a 40 um filter element.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 100 cc condensate bowl, while the balanced regulator maintains a steady outlet pressure. The pressed-in self-locking knob resists drift from vibration, and the included circular gauge with magnifier shows the set pressure on an MPa/psi scale.

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 GAFR40015AS Is Used
CNC machine tool circuits
Feed a 1/2in line to a CNC machining center's pneumatic clamps and tool changers, where the automatic drain keeps condensate from reaching sensitive valves.
Assembly line stations
Supply regulated air to multiple workstations on an assembly line, with the 100 cc bowl reducing drain frequency during continuous shifts.
Test bench air supply
Provide clean, stable pressure to a laboratory test bench running pneumatic actuators and gauges, relying on the 40 um element to protect instrumentation.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015AS the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow applications, as its flow curve is plotted to 7000 L/min at 0.7 MPa inlet, a step up from the GAFR300's 3500 L/min envelope. The PC bowl suits standard shop air, while the automatic drain handles unattended or wet lines without manual intervention. The standard type covers 0.15-0.9 MPa, and the included bracket simplifies panel mounting. The 40 um element handles general use, and the PT thread pairs with an MPa/psi gauge scale. If oil is needed downstream, order the matching GAFC400-15 combination instead. A 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 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 GAFR40015AS FAQ
It operates from 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g.
The automatic drain expels condensate without manual intervention, making it suitable for unattended operation or wet air lines. It replaces the semi-auto and manual drain options found on models without the A code.
