Airtac GAFR Adjustable Filter Regulator GAFR40015AL
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015AL 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR40015AL
The GAFR40015AL is a filter and regulator combined into a single body, saving space and reducing potential leak points compared to separate units. It handles a 1/2in port and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi), with a 40 um element for standard filtration.
This model features an automatic drain that expels condensate without manual intervention, making it suitable for wet or unattended lines. The 100 cc drain bowl and 880 g weight place it in the mid-size class, requiring a proper panel or frame mount rather than support from the tubing.

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 GAFR40015AL Is Used
Precision Fixturing
Feed a precise clamping fixture on a machining center where a stable, lower pressure is required to avoid damaging delicate workpieces.
Lab Air Supply
Provide clean, regulated air to a laboratory bench for pneumatic controls on test equipment that operates within a safe, low-pressure envelope.
Packaging Line Sensors
Supply a bank of pneumatic sensors and small actuators on a packaging line, where the automatic drain keeps the system running in humid conditions.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015AL the Right Air-Prep Unit?
Choose the GAFR40015AL when you need a 1/2in port with a lower pressure range, ideal for applications that never exceed 0.4 MPa. The automatic drain (A) is built in, so no manual draining is needed; the mounting bracket is included, and the circular gauge with MPa/psi scale is fitted. The 40 um element is the standard choice; upgrade to the 5 um (W) element for finer filtration if your precision valves demand it. If your line needs oil downstream, the matching GAFC400-15 combination adds a lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's regulated 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 GAFR40015AL FAQ
The GAFR40015AL is a filter & regulator with a 1/2in port. Its pressure range is 0.15-0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The operating temperature range is -5 to 70 C. It has a 100 cc drain bowl and weighs 880 g.
The automatic drain (A) expels accumulated condensate from the 100 cc bowl without manual intervention. This is ideal for unattended operation or lines with high moisture content, ensuring the filter continues to separate water and solids effectively.
