Airtac GAFR Adjustable Filter Regulator GAFR20008ALJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008ALJW 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 GAFR20008ALJW
The GAFR20008ALJW is a compact filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/4in port and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi), with a 5 um element for fine filtration.
This model features an automatic drain and a 25 cc condensate bowl, making it suitable for applications where regular manual draining is impractical. The circular gauge is fitted and reads in MPa/psi, allowing for precise set-point verification. It weighs only 290 g, so it is best mounted on a panel or frame rather than supported by the tubing.

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 GAFR20008ALJW Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a benchtop assembly fixture. The 5 um element protects the small valve from fine particulates, while the lower pressure range prevents over-clamping delicate parts.
Lab Air Supply
Provide clean, regulated air to a laboratory instrument that requires a gentle, consistent pressure. The automatic drain ensures the 25 cc bowl never overflows during extended experiments.
Paint Spraying Setup
Supply a small spray gun with filtered air at a stable low pressure. The compact 290 g body fits easily into a portable cart, and the gauge allows for quick adjustments between different coating materials.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008ALJW the Right Air-Prep Unit?
Choose the GAFR200 body for small actuators or single jigs; if you need more flow, step up to the GAFR300 with its 3500 L/min envelope at 0.7 MPa inlet. The PC bowl is the standard choice; select the metal or nylon bowl if your environment demands it, but confirm compatibility for aggressive surroundings. The automatic drain (A) is ideal for wet or unattended lines, while the blank code would have provided semi-auto and manual drains. The J code means no bracket is included, so plan for a panel mount or existing bracket. The 5 um element (W) traps finer particles than the standard 40 um, but will require more frequent service. The PT thread and MPa/psi gauge scale are standard. If you need lubrication downstream, order the matching GAFC200-08 combination instead. For this lower-pressure model, the 1.0 MPa max supply leaves about 0.6 MPa 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 GAFR20008ALJW FAQ
This filter & regulator has a working pressure range of 0.15-0.4 MPa (20-58 psi), a maximum 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 must not freeze. The unit has a 25 cc drain bowl and weighs 290 g.
The 'A' code specifies an automatic drain, which expels condensate without manual intervention, ideal for hard-to-reach or unattended installations. The 'J' code omits the mounting bracket, meaning you must use an existing bracket or a panel mount. This configuration is chosen when the unit is integrated into a larger control panel where space is tight and access is limited.
