Airtac GAFR Adjustable Filter Regulator GAFR30015ASNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ASNK 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 GAFR30015ASNK
The GAFR30015ASNK is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port and delivers a regulated output from 0.15-0.9 MPa (20-130 psi) with a standard 40 um filter element.
This model features an automatic drain that expels condensate without manual intervention, ideal for wet or unattended lines. The unit weighs 500 g and includes a mounting bracket, while the absence of a gauge means the 1/8in gauge port is available for a separate pressure indicator if needed.

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 GAFR30015ASNK Is Used
Machine Tool Air Supply
Feed a 1/2in line to a CNC machine's pneumatic clamping system, where the automatic drain keeps the 60 cc bowl from overflowing during long shifts and the regulated pressure stays stable for consistent clamping force.
Assembly Line Pneumatics
Supply filtered, regulated air to multiple workstations on an assembly line, with the 500 g body mounted on a central frame and the automatic drain reducing maintenance checks on the 60 cc condensate bowl.
Test Bench Instrument Air
Provide clean, regulated air to a test bench with precision valves, where the 40 um element protects sensitive components and the 0.15-0.9 MPa range covers most pneumatic testing requirements.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ASNK the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in piping where a 60 cc condensate bowl and 500 g mass suit the mounting structure. The automatic drain (A) eliminates manual draining tasks, while the included bracket simplifies installation. The 40 um element handles general workshop air, and the PT thread with MPa/psi gauge scale matches standard regional fittings. The reverse-flow (reflux) valve is fitted as an ordering option. For lines needing lubrication downstream, order the matching GAFC300-15 combination instead. 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 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 GAFR30015ASNK FAQ
The GAFR30015ASNK operates from 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. It has a 60 cc drain bowl, weighs 500 g, uses a 40 um element, and has a 1/8in gauge connection.
The automatic drain expels condensate from the 60 cc bowl automatically without manual operation. This is ideal for wet compressed air lines or installations where regular manual draining is impractical, ensuring the filter continues to separate water effectively.
