Airtac GAFR Adjustable Filter Regulator GAFR30010SJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010SJNW 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 GAFR30010SJNW
The GAFR30010SJNW is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate components. It has no lubricator and only one bowl, the 60 cc condensate drain bowl. This model uses a 3/8in port, works in the 0.15-0.9 MPa (20-130 psi) range, and comes with a 5 um filter element.
A balanced, self-locking regulator keeps the set pressure stable as supply varies, while the diversion structure spins air to drop liquid water and solid particles into the bowl. At 500 g, this unit is light enough for compact machines but still needs a proper panel mount since no bracket is included. The gauge connection is 1/8in if you add a pressure gauge later.

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 GAFR30010SJNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly machine. The 5 um element protects fine internal passages from particle wear, and the balanced regulator holds the set pressure steady as the line pressure fluctuates.
Test bench air supply
Supply clean, regulated air to a lab test fixture that checks actuator response. The 60 cc drain bowl gives enough condensate capacity for a full shift in moderate humidity, and the manual drain lets operators purge on a schedule.
Single-station automation
Power a single pick-and-place station on a light assembly line. The 3/8in port matches common tubing runs, and the 500 g weight is easy to mount on a machine frame with a custom panel.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010SJNW the Right Air-Prep Unit?
Choose the body and port first: GAFR300 with a 3/8in port sits between the smaller GAFR200 (plotted to 2000 L/min at 0.7 MPa inlet) and the larger GAFR400 (plotted to 7000 L/min at 0.7 MPa inlet). The PC bowl is the standard build, while C and N options are metal and nylon respectively. This model has a semi-auto drain plus a manual drain, so you can purge condensate automatically when pressure drops or do it by hand. The S type gives the full 0.15-0.9 MPa range, and the J code means no mounting bracket is included, so plan for a panel mount or reuse an existing bracket. With no gauge fitted, the 1/8in gauge connection is ready for an add-on. The 5 um element traps finer particles than the standard 40 um, which suits precision valves but requires more frequent servicing. PT thread is the default. If you need lubrication downstream, order the matching GAFC300-10 combination instead. Since the max supply pressure is 1.0 MPa, that leaves about 0.1 MPa above the 0.9 MPa top of the range, so keep the inlet near 1.0 MPa if you plan to set the outlet at 0.9 MPa.
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 GAFR30010SJNW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -5 to 70 C and the unit must not freeze. The drain bowl holds 60 cc and the total weight is 500 g. The filter element is 5 um and the port is 3/8in.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one to the 1/8in gauge connection. The J code means the mounting bracket is omitted, which suits installations where the unit goes into a panel or onto an existing bracket. Both options reduce cost when you already have these parts.
