Airtac GAFR Adjustable Filter Regulator GAFR30015ALNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ALNK 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 GAFR30015ALNK
The GAFR30015ALNK is a filter and regulator combined in a single body, so it cleans the air and sets a steady outlet pressure without needing a separate filter plus regulator pair. This 1/2in version has a 40 um element and a lower-pressure range of 0.15-0.4 MPa (20-58 psi), with a 60 cc condensate bowl and a 500 g mass that suits a fixed panel mount.
Its automatic drain clears collected water without manual attention, and the reverse-flow (reflux) valve is fitted as an ordering difference. The balanced regulator holds the set pressure as supply varies, and the pressed-in knob resists drift from vibration, so the outlet stays stable in service.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR300 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR30015ALNK Is Used
Precision valve control
Feed a single precision valve or a small instrument loop that needs a stable, low-pressure supply. The balanced regulator holds the setpoint as line pressure fluctuates, and the 40 um element protects the valve from particles.
Wet-line automation cell
Use on a machine cell with frequent condensate in the air. The automatic drain clears the 60 cc bowl without operator rounds, keeping the lower-pressure setpoint steady for the cycle.
Bench test rig
Mount on a test bench where a 1/2in line feeds a regulated low-pressure zone. The included bracket fixes the 500 g unit to the frame, and the PT thread connects to standard local fittings.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ALNK the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in piping where the lower-pressure range (0.15-0.4 MPa) is sufficient; if the machine may ever need more than 0.4 MPa, select the standard S type instead. The PC bowl and automatic drain suit a clean, dry environment with wet lines, while the included bracket and PT thread (MPa/psi gauge scale) match most installations. The 5 um element option (W) is available if finer filtration is needed, and the no-gauge version leaves the 1/8in gauge connection open for a later add-on. For oil downstream, order the matching GAFC300-15 combination rather than this unit. 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 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 GAFR30015ALNK FAQ
It is a filter & regulator with a 1/2in port, 0.15-0.4 MPa (20-58 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, and -5 to 70 C temperature range. The drain bowl holds 60 cc, the unit weighs 500 g, and the element is 40 um.
The L code sets the range to 0.15-0.4 MPa for low-pressure applications, while the N after the port means no gauge is supplied; the 1/8in gauge connection is left open for a later add-on. The K code adds a reverse-flow (reflux) valve as an ordering difference.
