Airtac GAFR Adjustable Filter Regulator GAFR200C08LJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08LJN 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR200C08LJN
The GAFR200C08LJN is a filter and regulator combined into a single body, so the incoming air is cleaned and then set to a steady outlet pressure without needing separate units. This 1/4in version uses a metal bowl and a 40 um element, with a lower-pressure range of 0.15-0.4 MPa (20-58 psi) suited to gentle, consistent pneumatic tasks.
Because the filter and regulator share one housing, there are fewer joints to seal and less rail space consumed than with a separate GAF filter plus GAR regulator. The metal bowl is a build choice for the condensate collection area; the common 1.0 MPa (145 psi) maximum and -5 to 70 C temperature limits apply unchanged.

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.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC200-08 F.R.L. combination instead.

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 GAFR200C08LJN Is Used
Precision fixturing
Feed a small pneumatic clamp or fixture on an assembly bench where a steady 0.15-0.4 MPa supply keeps delicate parts held without excessive force.
Bench tool air
Supply a compact air tool or blow gun station where the lower pressure range protects sensitive components and the metal bowl resists rough workshop handling.
Prototype rigs
Use on a test rig or prototype setup where the 1/4in port and 290 g body mount easily on a small panel, and the semi-auto drain allows quick manual checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08LJN the Right Air-Prep Unit?
Choose the GAFR200 body for small jigs or single actuators where a 1/4in port and a 290 g unit fit neatly. The metal bowl (C) is specified here; the 25 cc drain bowl collects condensate and is emptied via the semi-auto and manual drains that are both fitted. This L-type is capped at 0.4 MPa, so if the machine may ever need more pressure, select the standard S type instead. No bracket (J) is included, meaning you must provide a panel mount or existing bracket; the gauge is omitted (N), but the 1/8in gauge connection is ready if you add one later. The 40 um element handles general workshop air, and the PT thread suits standard installations. For lines that need oil downstream, order the matching GAFC200-08 combination rather than this unit. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this range, so plan the inlet pressure accordingly.
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 GAFR200C08LJN FAQ
Pressure range is 0.15-0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Operating temperature is -5 to 70 C. The drain bowl holds 25 cc and the unit weighs 290 g with a 1/4in port and 40 um element.
The J code means the mounting bracket is omitted, so you must use a panel mount or an existing bracket. The N code after the port means no gauge is supplied, but the 1/8in gauge connection is present if you add one later. Both options reduce the initial cost when you already have these accessories.
