Airtac GAFR Adjustable Filter Regulator GAFR200N08ASJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ASJ 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR200N08ASJ
The GAFR200N08ASJ is a genuine AirTAC filter & regulator that combines both functions in a single body, saving rail space and reducing potential leak points compared to separate units. It handles 1/4in ports, regulates from 0.15-0.9 MPa (20-130 psi), and filters to 40 um, with a nylon bowl that offers a different build option without changing the 1.0 MPa max pressure rating.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 25 cc drain bowl, while the balanced regulator mechanism holds the set outlet pressure steady as supply varies. The pressed-in self-locking knob resists drift from vibration, and this model includes the automatic drain for unattended operation, though it ships without the mounting bracket.

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 GAFR200N08ASJ Is Used
Compact jig actuation
Feed a single pneumatic jig or fixture on an assembly bench where 1/4in tubing and a 290 g body keep the setup light and close to the cylinder.
Prototype test rigs
Use on a lab or R&D test stand that needs clean, regulated air for a single actuator or small valve manifold without dedicating space to a larger filter unit.
Maintenance workstations
Mount on a mobile maintenance cart to provide filtered, pressure-controlled air for pneumatic hand tools or cleaning nozzles in a workshop.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ASJ the Right Air-Prep Unit?
Choose this GAFR200N08ASJ for a compact 1/4in line where you need both filtration and pressure control in one footprint. The nylon bowl (N) is a material choice for your environment, while the automatic drain (A) suits wet or unattended lines; the standard S type covers 0.15-0.9 MPa, and the omitted bracket (J) fits existing panel mounts. The 40 um element handles general shop air, and the PT thread comes with an MPa/psi gauge scale; if you need finer filtration, the W option drops to 5 um, and a K adds a reverse-flow valve. For lines needing oil downstream, the matching GAFC200-08 combination adds a lubricator. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 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 GAFR200N08ASJ FAQ
This filter & regulator has a 1/4in port, working pressure range of 0.15-0.9 MPa (20-130 psi), 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, with a 40 um element and automatic drain.
The N code specifies a nylon bowl as a material choice, while the J code means the mounting bracket is omitted for installations using existing brackets or panel mounts. The nylon bowl shares the same 1.0 MPa max pressure and -5 to 70 C temperature range as the PC or metal options.
