Airtac GAFR Adjustable Filter Regulator GAFR30008S
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008S 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 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 GAFR30008S
The GAFR30008S is a genuine AirTAC filter & regulator, combining both functions in a single body to save space and reduce potential leak points. It handles a 1/4in port with a 40 um element, delivering clean, regulated air from 0.15-0.9 MPa (20-130 psi).
The unit's diversion structure spins incoming air to separate liquid water and solid particles into its 60 cc condensate bowl. A balanced, self-locking regulator holds the outlet pressure steady, and the included circular gauge with MPa/psi scale lets you monitor the set point directly.

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 GAFR30008S Is Used
Precision Jig Fixtures
Feed a single pneumatic clamp or positioning jig on an assembly bench. The 1/4in port and 40 um element suit compact tooling that needs steady, filtered actuation.
Test Bench Air Supply
Provide a clean, regulated air source for a laboratory test fixture or calibration setup. The integrated gauge allows quick verification of the set pressure before each run.
Single Actuator Control
Operate a small cylinder or air tool in a maintenance workshop. The 60 cc bowl handles typical condensate from a short line, and the semi-auto drain allows easy manual purging.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008S the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports, with a 60 cc drain bowl and a flow envelope plotted to 3500 L/min at 0.7 MPa inlet. This model includes the mounting bracket and a circular gauge, while the semi-auto and manual drains are both fitted for flexible operation. The standard pressure type covers 0.15-0.9 MPa (20-130 psi), and the PC bowl is the default build. If you need finer filtration, select the W option for a 5 um element, or add the K code for a reverse-flow valve. For lines requiring oil downstream, order the matching GAFC300-08 combination instead. Remember that 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.
