Airtac GAFR Adjustable Filter Regulator GAFR200C08ASJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08ASJ 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 GAFR200C08ASJ
The GAFR200C08ASJ is a filter & regulator that combines air filtration and pressure regulation in a single body, eliminating the need for separate GAF and GAR units. It features a metal bowl and a 1/4in port, with a working pressure range of 0.15-0.9 MPa (20-130 psi) and a 40 um filtering element.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 25 cc drain bowl, while the balanced regulator holds the outlet pressure steady as supply varies. The pressed-in self-locking knob resists drift from vibration, and the automatic drain handles condensate without manual intervention.

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 GAFR200C08ASJ Is Used
Compact jig actuation
Feed a single pneumatic jig or fixture on an assembly bench, where the 1/4in port and 290 g body mount neatly on a small panel without taking up rail space.
Prototype test rigs
Supply clean, regulated air to a laboratory test setup with a single actuator, relying on the automatic drain to handle condensate during extended unattended runs.
Small workshop tools
Power a handheld air tool or small cylinder in a repair shop, where the metal bowl resists knocks and the self-locking knob keeps the set pressure stable despite tool vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08ASJ the Right Air-Prep Unit?
Choose the GAFR200C08ASJ for a compact 1/4in line where space is tight, as its 290 g weight suits panel mounting rather than tubing support. The metal bowl is a build choice for demanding environments, though the common 1.0 MPa max and -5 to 70 C rating applies to all bowl materials, so confirm compatibility for aggressive surroundings. The automatic drain (A) suits unattended or wet lines, while the missing bracket (J) is for existing panel mounts; the fitted circular gauge reads in MPa/psi on the PT thread. For finer filtration, select the W option for a 5 um element, and if oil is needed downstream, order the matching GAFC200-08 combination instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa for maximum outlet pressure.
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 GAFR200C08ASJ FAQ
The GAFR200C08ASJ operates from 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C and must not freeze. The drain bowl holds 25 cc, the unit weighs 290 g, and the flow curve is plotted to 2000 L/min at 0.7 MPa inlet.
The J code means the mounting bracket is omitted, intended for installations where the unit is panel-mounted or uses an existing bracket. If you need the standard bracket, order without the J code, such as GAFR200C08AS.
