Airtac GAFR Adjustable Filter Regulator GAFR20008LW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008LW 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR20008LW
The GAFR20008LW is a filter and regulator combined into one compact body, so it cleans the air and stabilizes the outlet pressure without needing separate units. This 1/4in version uses a 5 um element to trap fine particles, and its lower-pressure range of 0.15-0.4 MPa (20-58 psi) suits delicate circuits.
Its single 25 cc condensate bowl collects water and solids spun out by the diversion structure, and the pressed-in self-locking knob keeps the set pressure stable against vibration. Weighing just 290 g, it is the lightest body in the GAFR family, designed for small jigs or single actuators.

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 GAFR20008LW Is Used
Precision valve control
Feed a single precision pneumatic valve or a small instrument air circuit that needs a stable low pressure. The 5 um element keeps fine particles away from sensitive internals.
Bench jig or fixture
Mount this 290 g unit on a workbench to supply a clamping jig or a small fixture. The included bracket simplifies panel mounting, and the compact body saves rail space.
Lab or test setup
Use the lower-pressure range to regulate air for a lab test rig or a prototype station. The 25 cc bowl is easy to check, and the manual drain gives you control over purging.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008LW the Right Air-Prep Unit?
Choose the GAFR200 body for 1/8in or 1/4in ports; this model uses the 1/4in port and is the entry point of the series. The PC bowl is the standard build, while the 5 um element filters finer than the 40 um default, making it a good fit for precision valves or instrument air. It ships with both semi-auto and manual drains, and the mounting bracket is included for panel installation.
Since this is an L-type, the regulated range tops out at 0.4 MPa, so confirm your circuit never needs more than that. The fitted gauge reads in MPa/psi, and the thread is PT. If you need lubrication downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the range.
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 GAFR20008LW FAQ
The GAFR20008LW is a filter & regulator with a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 5 um filter element. Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The condensate bowl holds 25 cc, and the unit weighs 290 g.
The L in the code indicates the lower-pressure type, which regulates from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. This is designed for applications that need a gentle, consistent low pressure, such as delicate actuators or precision air tools. If your circuit might require more than 0.4 MPa, the standard S-type would be a better choice.
