Airtac GAFR Adjustable Filter Regulator GAFR200N08LW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08LW 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 GAFR200N08LW
The GAFR200N08LW is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing two separate units. This model uses a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 5 um element that traps finer particles than the standard 40 um grade.
The nylon bowl holds 25 cc of condensate and is drained using both the semi-auto and manual drains fitted as standard. Weighing 290 g, this compact unit is suited for light-duty circuits; the included mounting bracket provides secure installation without stressing 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 GAFR200N08LW Is Used
Precision valve control
Feed a small pneumatic valve or a single actuator that requires clean air and a stable, low set pressure. The 5 um element protects fine internal passages from particle wear.
Bench-mounted jig
Supply a workshop jig or a light clamping fixture where space is tight. The compact 290 g body and included bracket mount neatly on a panel or frame.
Instrument air line
Protect a sensitive gauge or analyzer with the 5 um element and a regulated output that stays within the lower 0.15-0.4 MPa band, ideal for low-pressure test setups.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08LW the Right Air-Prep Unit?
Choose the GAFR200N08LW for a 1/4in line that needs fine filtration and a regulated output capped at 0.4 MPa. The nylon bowl is a build choice for the environment, while the 5 um element suits precision valves or instrument air but will need more frequent service than a 40 um element. The semi-auto and manual drains are both fitted, and the included bracket simplifies mounting; the circular gauge with an MPa/psi scale is supplied. If the line also needs lubrication downstream, order the matching GAFC200-08 combination instead, as this unit does not add oil. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the 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 GAFR200N08LW FAQ
The GAFR200N08LW is a filter & regulator with a 1/4in port. Its pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 25 cc drain bowl, and weighs 290 g.
The 'L' type is designed for applications that only need up to 0.4 MPa, offering finer adjustment within that band. The 'W' element filters to 5 um, trapping much finer particles than the standard 40 um, which is better for sensitive equipment but requires more frequent element changes.
