Airtac GAFR Adjustable Filter Regulator GAFR30008SNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008SNW 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 1/4" 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 GAFR30008SNW
The GAFR30008SNW is a genuine AirTAC filter & regulator that combines both functions in a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/4in port with a 500 g body, making it a compact choice for smaller machines.
This model operates in the standard 0.15-0.9 MPa (20-130 psi) range and comes with a 5 um element for finer filtration. The PC bowl and semi-auto+manual drain are standard, and the unit is rated for -5 to 70 C operation without freezing.

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 GAFC300-08 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 GAFR30008SNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves with cleaner 5 um filtered air, protecting fine internal orifices from premature wear.
Single actuator station
Supply a single 1/4in actuated valve or small cylinder with regulated pressure, keeping the setpoint stable despite supply fluctuations.
Bench assembly tooling
Power pneumatic screwdrivers or presses on an assembly bench, where the compact 500 g body mounts easily to a frame or panel.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008SNW the Right Air-Prep Unit?
Choose this GAFR300 if you need a 1/4in port and a 60 cc condensate bowl, which requires less frequent draining than the 25 cc bowl on a GAFR200. The PC bowl is the standard build, while the 5 um element traps finer particles for sensitive equipment. This model includes the mounting bracket, has no gauge (the 1/8in connection is ready for one), and uses PT threads. If oil is needed downstream, order the matching GAFC300-08 combination instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30008SNW FAQ
It is a filter & regulator with a 1/4in port, working pressure 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 60 cc drain bowl, and 500 g weight. It has a 5 um element and a PC bowl.
The N code means no gauge is supplied, so the set pressure cannot be read directly. The gauge connection is 1/8in, so you can add a compatible AirTAC gauge later if needed.
