Airtac GAFR Adjustable Filter Regulator GAFR300N10SJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300N10SJWK 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 5 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 GAFR300N10SJWK
The GAFR300N10SJWK is a filter and pressure regulator combined into a single body, so incoming air is spun to separate liquid water and solid particles before a balanced, self-locking mechanism sets a steady outlet pressure. This nylon-bowl unit uses a 3/8in port and a 5 um element, with a working range of 0.15-0.9 MPa (20-130 psi).
Because the filter and regulator share one housing, this part replaces a separate GAF filter plus a GAR regulator, reducing potential leak points and saving rail space. The 60 cc condensate bowl collects what the diversion structure removes, and the pressed-in self-locking knob resists set-pressure drift from vibration.

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 GAFR300N10SJWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station where the 5 um element protects fine internal passages and the stable regulated pressure holds setpoints.
Test bench air supply
Supply a lab test fixture that needs clean, regulated air at a fixed pressure, with the semi-auto drain letting an operator purge condensate between test runs.
Single actuator line
Protect and regulate air for one indexing cylinder on a packaging machine, where the compact 500 g body mounts directly to a panel without bracket support.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300N10SJWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in to 1/2in port lines; this 3/8in version sits between the smaller GAFR200 (25 cc bowl, 2000 L/min envelope) and the larger GAFR400 (100 cc bowl, 7000 L/min envelope). The nylon bowl is a build choice with the same 1.0 MPa max and -5 to 70 C rating as PC or metal, so confirm compatibility for aggressive surroundings. Both semi-auto and manual drains are fitted, the 5 um element traps finer particles than the standard 40 um, and the PT thread gives an MPa/psi gauge scale. The J code omits the mounting bracket, and the K code adds a reverse-flow valve as an ordering difference. If oil is needed downstream, order the matching GAFC300-10 combination instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range.
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 GAFR300N10SJWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), and proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C and must not freeze. The drain bowl holds 60 cc, the unit weighs 500 g, and the flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The K code indicates a reverse-flow (reflux) valve is fitted to the GAFR300N10SJWK. It is an ordering difference shown as a separate pneumatic symbol; the catalogue defers its function to another page, so treat it as a specified option rather than a standard feature.
