Airtac GAFR Adjustable Filter Regulator GAFR20008SK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008SK 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 GAFR20008SK
The AirTAC GAFR20008SK is a filter and regulator combined into a single body, so it cleans incoming air and stabilizes outlet pressure without needing separate components. This 1/4in unit operates from 0.15 to 0.9 MPa (20-130 psi) and uses a 40 um element, with the reverse-flow valve fitted as an ordering difference.
Its diversion structure spins the air to separate liquid water and solid particles into the 25 cc drain bowl, while the balanced, self-locking regulator keeps the set pressure steady as supply varies. The included mounting bracket and circular gauge with MPa/psi scale make it a compact, ready-to-install package for small pneumatic circuits.

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 GAFC200-08 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 GAFR20008SK Is Used
Precision Jig Fixturing
Feed a single pneumatic clamp or a small indexing jig with clean, regulated air. The 1/4in port and 290 g mass suit compact bench-mounted tooling where space is tight.
Prototype Test Rigs
Use it on a laboratory bench to supply a consistent 0.15-0.9 MPa to a prototype valve or actuator. The 40 um element protects sensitive components from pipe scale and water droplets.
Portable Service Kit
Mount it on a small cart or panel to provide filtered, regulated air for maintenance tools. The included bracket and lightweight build make it easy to move between workstations.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008SK the Right Air-Prep Unit?
Choose the GAFR200 body for small jigs or single actuators; if you need more flow, step up to the GAFR300 with its 3500 L/min envelope at 0.7 MPa inlet. This model has a PC bowl, a semi-auto plus manual drain, and a standard pressure type, with the mounting bracket included and a 40 um element. The PT thread sets the gauge scale to MPa/psi, and the K code adds the reverse-flow valve without altering the pressure range. For lines needing oil downstream, order the matching GAFC200-08 combination instead of this unit. Since the max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, plan your inlet pressure near the maximum to reach the highest setpoint.
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 290 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 GAFC200-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR20008SK FAQ
The GAFR20008SK is a filter & regulator with a 1/4in port, working pressure of 0.15-0.9 MPa (20-130 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 25 cc drain bowl, weighs 290 g, and uses a 40 um element.
The K code indicates the reverse-flow (reflux) valve is fitted. It is an ordering difference from models without K; the catalogue does not detail its function in our data, so treat it as a specified option for your application.
