Airtac GAFR Adjustable Filter Regulator GAFR20008AL
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008AL 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR20008AL
The GAFR20008AL is a compact filter & regulator from AirTAC, combining air filtration and pressure regulation in a single body. This unit handles a 1/4in port and operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi), with a standard 40 um filter element. Its integrated design replaces a separate filter and regulator, reducing potential leak points and saving valuable space on your machine.
Weighing just 290 g, this small-format unit is ideal for tight installations where a lightweight component is needed. The automatic drain (A) efficiently expels condensate from the 25 cc bowl without manual intervention, making it suitable for unattended operation. A circular gauge with an MPa/psi scale is fitted, allowing you to monitor the set pressure directly.

Where the Airtac GAFR Adjustable Filter Regulator GAFR20008AL Is Used
Precision Fixtures
Feed a single precision clamping fixture or a small indexing table with stable, regulated air. The lower pressure range is well-suited for delicate operations that require a gentle, consistent force.
Bench-Mount Tools
Power a small bench-mounted pneumatic press or a parts-feeder bowl with clean, regulated air. The compact 290 g body and 1/4in port fit neatly into a tool pedestal or workbench setup.
Lab Air Supply
Provide a clean, low-pressure air source for a laboratory test jig or a small pneumatic actuator in a research setup. The automatic drain ensures the 25 cc bowl stays clear of condensate during long experiments.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008AL the Right Air-Prep Unit?
Choose the GAFR20008AL when your application needs a compact 1/4in filter & regulator with a lower pressure range. The L type is specifically designed for systems that never require more than 0.4 MPa (58 psi), making it a precise fit for delicate operations. The automatic drain is a key feature for lines that are wet or run unattended, as it removes the need for manual draining. The included mounting bracket simplifies installation, and the 40 um element handles standard workshop air. For finer filtration, consider the W option for a 5 um element. If your system requires lubrication downstream, you would need the matching GAFC200-08 combination, as this unit does not add oil. Note that the 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, providing a comfortable margin for consistent regulation.
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 GAFR20008AL FAQ
This is a filter & regulator with a 1/4in port. The pressure range is 0.15-0.4 MPa (20-58 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C and has a 25 cc condensate bowl. The unit weighs 290 g and comes with a 40 um filter element.
The L type is designed for applications that only need a maximum of 0.4 MPa (58 psi). This allows for finer adjustment and stability within that lower band. If your machine could ever require more pressure, the standard S type (0.15-0.9 MPa) would be the correct choice.
