Airtac GAFR Adjustable Filter Regulator GAFR30015LWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015LWK 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30015LWK
The GAFR30015LWK is a filter and regulator combined in a single body, handling both filtration and pressure control in one compact unit. It has a 1/2in port, a lower pressure range of 0.15-0.4 MPa (20-58 psi), and a 5 um filter element for finer particle removal.
This model includes a circular gauge with MPa/psi scale, a mounting bracket, and a reverse-flow (reflux) valve fitted. The 60 cc condensate bowl collects water and solids separated by the diversion structure, and the semi-auto plus manual drain gives you both automatic purging and manual control.

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 GAFR30015LWK Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves from fine particles, while the lower pressure range suits delicate actuation tasks.
Bench test rigs
A 1/2in port and 500 g weight make this suitable for stationary test equipment where stable low pressure is needed.
Light assembly lines
The 60 cc bowl and semi-auto drain handle condensate in intermittent duty cycles typical of small assembly stations.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015LWK the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in port applications needing moderate flow, with a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The lower pressure type (L) caps at 0.4 MPa, so verify your system never needs more than that. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent service. The included bracket simplifies mounting, and the fitted gauge shows pressure in MPa/psi. The reverse-flow valve is an ordering difference only. If you need lubrication downstream, order the matching GAFC300-15 combination instead. 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.
