Airtac GAFR Adjustable Filter Regulator GAFR30015ALN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ALN 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 GAFR30015ALN
The GAFR30015ALN is a filter and regulator combined into one body, so the incoming air is spun to separate liquid water and solid particles before a balanced regulator sets a steady outlet pressure. This lower-pressure version delivers 0.15-0.4 MPa (20-58 psi) through its 1/2in port, with a 40 um element and an automatic drain that clears the 60 cc condensate bowl without manual attention.
Because the filter and regulator share a single housing, this unit replaces what would otherwise be two separate components, reducing the number of joints to seal and saving space on the rail. The pressed-in self-locking knob resists set-pressure drift from vibration, keeping the outlet stable even on machinery that shakes.

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 GAFR30015ALN Is Used
Precision valve control
Feed a single precision pneumatic valve or a small instrument loop where a steady 0.15-0.4 MPa supply is needed and the automatic drain keeps the bowl from filling during long production runs.
Wet utility lines
Mount on a machine header fed by a wet or poorly maintained compressor line; the diversion filter removes water and solids while the automatic drain cycles without operator intervention.
Bench assembly stations
Use at a manual assembly bench with a single air tool or vacuum generator, where the lower pressure range protects delicate operations and the included bracket simplifies mounting.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ALN the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in porting with a 60 cc drain bowl and a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The L type caps the regulated range at 0.4 MPa, so if your process may ever need more than that, select the standard S type instead. The automatic drain suits unattended or wet lines, while the included mounting bracket lets you fix the 500 g unit to a panel or frame rather than supporting it from the tubing. No gauge is fitted, but the 1/8in gauge connection is ready if you add one later. The PC bowl and 40 um element cover general shop air; if you need finer filtration, order the W element option. For lines that require oil downstream, the matching GAFC300-15 combination adds a lubricator. Note that 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFR30015ALN FAQ
The GAFR30015ALN is a filter & regulator with a 1/2in port, working pressure range 0.15-0.4 MPa (20-58 psi), maximum pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um filter element, 60 cc drain bowl, and weight of 500 g. It has an automatic drain, no gauge, and the mounting bracket is included.
The L code sets the regulated range to 0.15-0.4 MPa (20-58 psi) for applications that need gentle, consistent pressure. The N code means no gauge is supplied, but the 1/8in gauge connection is present if you add one. If you need a higher range, choose the standard S type instead.
