Airtac GAFR Adjustable Filter Regulator GAFR20008ALNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008ALNW 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 GAFR20008ALNW
The GAFR20008ALNW is a filter & regulator with both functions in a single body, so it replaces a separate filter plus regulator with fewer joints to seal. It uses a 1/4in port and a 5 um element, and its lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi).
The diversion structure spins incoming air to drop liquid water and solid particles into the 25 cc condensate bowl, while the balanced, self-locking regulator holds the set outlet steady as supply pressure varies. This 290 g unit ships with the mounting bracket included, and the automatic drain handles condensate without manual attention.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR200 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR20008ALNW Is Used
Precision valve control
Feed a single pneumatic valve or small actuator that needs clean air and a stable lower pressure. The 5 um element protects fine internals, and the balanced regulator holds the setpoint as shop pressure fluctuates.
Bench test rig
Supply a lab or workbench fixture with filtered air at a controlled low pressure. The automatic drain keeps the 25 cc bowl from overflowing during long test runs, and the compact 290 g body mounts easily on a rail.
Light assembly station
Power a small clamping or positioning cylinder on an assembly line. The 1/4in port matches common tubing, and the included bracket secures the unit without stressing the pipework.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008ALNW the Right Air-Prep Unit?
Choose the GAFR200 body for a single actuator or small jig, where the 1/4in port and 2000 L/min plotted flow envelope at 0.7 MPa inlet suit light duty. The PC bowl is the standard build, while the 5 um element traps finer particles for precision valves, though it needs more frequent service than a 40 um element. The automatic drain (A) suits wet or unattended lines, and the included bracket simplifies panel mounting. No gauge is fitted, so the 1/8in gauge connection is available if you add one later. If the line needs oil downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of this unit's regulated 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 GAFR20008ALNW FAQ
This filter & regulator has a 1/4in port, a 5 um element, and a lower-pressure range of 0.15-0.4 MPa (20-58 psi). 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 drain bowl holds 25 cc, the unit weighs 290 g, and it has an automatic drain.
The N code after the port means no gauge is supplied, so the set pressure cannot be read directly. The gauge connection is 1/8in, and you can fit an AirTAC gauge there later if you need to monitor the outlet pressure.
