Airtac GAFR Adjustable Filter Regulator GAFR30010SJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010SJ 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 GAFR30010SJ
The GAFR30010SJ is a filter and regulator combined in one body, so incoming air is spun to separate liquid water and solid particles before a balanced regulator sets a steady outlet pressure. This 3/8in unit works across 0.15-0.9 MPa (20-130 psi) with a 40 um element, and it has no lubricator - it only filters and regulates.
Weighing 500 g, this GAFR300 body carries a 60 cc condensate bowl and a circular gauge with MPa/psi scale. The pressed-in self-locking knob resists set-pressure drift from vibration, while the single-body design means fewer joints to seal than a separate filter plus regulator.

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 GAFR30010SJ Is Used
Jig and fixture circuits
Feed a single clamping jig or a small indexing fixture with clean, regulated air at a stable 0.15-0.9 MPa. The 3/8in port matches typical valve manifolds on benchtop assembly stations.
Machine tool coolant valves
Supply a coolant control valve on a lathe or mill where the 40 um element protects the valve pilot from pipe scale and rust particles. The 500 g body mounts easily on a machine panel.
Pick-and-place grippers
Run a pneumatic gripper on a small pick-and-place arm with a steady outlet pressure. The 60 cc bowl handles normal condensate between shifts, and the manual drain gives quick service.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010SJ the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in to 1/2in port lines; this 3/8in version suits medium-flow circuits. The PC bowl (blank code) is the standard build, and the semi-auto plus manual drain gives you both automatic condensate release and a manual override. This model ships without the mounting bracket (J code), so plan for panel mounting or an existing bracket. The 40 um element is the default grade; select W for 5 um filtration if you need finer particle removal. The PT thread means the fitted gauge reads in MPa/psi. If your line needs oil 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 GAFR30010SJ FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g. It has a 3/8in port, 40 um element, and a semi-auto plus manual drain.
The J code in GAFR30010SJ means the mounting bracket is omitted. This suits installations where the unit mounts directly to a machine panel or uses an existing bracket from a previous regulator. If you need the standard bracket, order the same model without the J code.
