Airtac GAFR Adjustable Filter Regulator GAFR30010LJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LJNW 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30010LJNW
The GAFR30010LJNW is a compact filter & regulator from AirTAC, combining both functions in a single body to save space and reduce potential leak points. This model has a 3/8in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 5 um filter element for finer particle removal.
Its 60 cc condensate bowl collects water and solids separated by the internal diversion structure, and the 500 g weight indicates a unit that needs proper mounting support. The semi-auto and manual drains are both fitted, and the absence of a gauge means the 1/8in gauge connection is available for adding one 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.

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 GAFR30010LJNW Is Used
Precision pneumatic controls
The 5 um element and lower pressure range make this GAFR300 suitable for feeding sensitive pilot valves or precision regulators on a small machine station.
Bench assembly fixtures
A 3/8in port and 500 g weight fit a bench-mounted assembly jig where a steady 0.15-0.4 MPa supply is needed for a single pneumatic actuator.
Compact panel builds
The single-body design and no-bracket option suit a dense control panel where space is tight and the unit can be mounted directly to a frame.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010LJNW the Right Air-Prep Unit?
This GAFR300 is the mid-size body, with a 3/8in port and a flow curve plotted to 3500 L/min at 0.7 MPa inlet, making it a step up from a GAFR200 for slightly larger demands. The PC bowl is the standard build, and the 5 um element suits precision applications but will need more frequent service than a 40 um version. The L-type pressure range tops out at 0.4 MPa, so confirm your system never needs more than that; the J code means no bracket is included, and the N code means no gauge is fitted, leaving a 1/8in connection for a field-installed unit. The PT thread with MPa/psi scale is standard, and if you need lubrication downstream, the matching GAFC300-10 combination adds a lubricator. A 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 (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 GAFR30010LJNW FAQ
This is a filter & regulator with a 3/8in port, lower-pressure range of 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -5 to 70 C. It has a 60 cc drain bowl, weighs 500 g, and uses a 5 um element.
The J code omits the mounting bracket for installations using an existing bracket or panel mount, while the N code omits the gauge, leaving a 1/8in gauge connection for adding one later. This allows a custom build without paying for components you do not need.
