Airtac GAFR Adjustable Filter Regulator GAFR30010ASNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ASNK 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 3/8" 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 GAFR30010ASNK
The GAFR30010ASNK is a filter and regulator combined in a single body, so it cleans incoming air and sets a steady outlet pressure without needing separate units. This model uses a 3/8in port, a 40 um element, and a standard pressure range of 0.15-0.9 MPa (20-130 psi).
Its automatic drain clears condensate without manual attention, and the 60 cc bowl holds the collected water and solids. The pressed-in self-locking knob resists drift from vibration, keeping the set pressure stable during operation.

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 GAFC300-10 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 GAFR30010ASNK Is Used
Precision jig clamping
Feed a single clamping fixture on a machining station where steady pressure is needed to hold parts consistently. The 40 um element protects the clamp valve from particles.
Lab air supply
Supply a small test bench or analytical instrument that needs clean, regulated air. The automatic drain keeps the bowl from filling up during long experiments.
Assembly workstations
Power a pneumatic screwdriver or small actuator on an assembly line. The 3/8in port matches common tooling connections, and the 500 g body mounts easily on a rail.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010ASNK the Right Air-Prep Unit?
Choose this GAFR300 if your line needs a 3/8in port and the 500 g body suits your mounting space. The PC bowl is the standard choice; if you need a different material, consider the C (metal) or N (nylon) versions. The automatic drain (A) is ideal for unattended or wet lines, while a blank drain code would give both semi-auto and manual drains. This unit includes the mounting bracket and has no gauge, so the 1/8in gauge connection is available if you add one later. The 40 um element handles general shop air, and the PT thread matches the MPa/psi gauge scale. The K code means a reverse-flow valve is fitted, which is an ordering difference to note. If your application needs lubrication downstream, order the matching GAFC300-10 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure near the maximum for full output.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30010ASNK FAQ
This filter & regulator has a 3/8in port, a pressure range of 0.15-0.9 MPa (20-130 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. The element is 40 um, and it has an automatic drain.
The K code indicates that a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference from models without the K code. The function of this valve is detailed in the catalogue on a page not included in our data, so we do not explain its operation here.
