Airtac GAFR Adjustable Filter Regulator GAFR20008LNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008LNW 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 GAFR20008LNW
The GAFR20008LNW is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi) and uses a 5 um element for finer filtration.
This compact 290 g unit with a 1/4in port is sized for small jigs and single actuators. The 25 cc condensate bowl collects water and solids separated by the internal diversion structure, and the included mounting bracket provides stable installation.

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 GAFR20008LNW Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves from fine particulate, while the lower pressure range suits delicate actuation tasks.
Small bench fixtures
Ideal for compact bench presses or clamping fixtures where a 1/4in port and light 290 g body are easy to mount and adjust.
Lab air supply
Provides filtered, regulated air at a stable low pressure for lab equipment that cannot tolerate pressure spikes or contamination.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008LNW the Right Air-Prep Unit?
Choose this GAFR200 for applications needing a compact 1/4in port and a lower pressure ceiling. The 5 um element traps finer particles than the standard 40 um, making it suitable for precision valves, though it will require more frequent service. The semi-auto and manual drains are both fitted, allowing flexible condensate removal. The mounting bracket is included for secure panel mounting. The L-type regulator tops out at 0.4 MPa, so confirm your machine never needs more than this. If oil is needed downstream, order the matching GAFC200-08 combination instead. With no gauge fitted, the 1/8in gauge connection is ready for a field-installed unit. 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 GAFR20008LNW FAQ
The GAFR20008LNW is a filter & regulator with a 1/4in port. Pressure range is 0.15-0.4 MPa (20-58 psi). Max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 25 cc condensate bowl and weighs 290 g.
The L in the model code indicates a lower-pressure regulator, designed for applications that require a maximum of 0.4 MPa. This provides finer adjustment within that band compared to the standard 0.9 MPa type, but it cannot be used where higher pressures are needed.
