Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJN 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 GAFR200C08ALJN
This AirTAC GAFR200C08ALJN combines a filter and a pressure regulator in a single body, so it cleans incoming air and holds a steady outlet pressure without needing separate components. It has no lubricator and only one bowl, the 25 cc condensate bowl. The unit uses a 1/4in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 40 um element, with the filter spinning air to drop liquid water and solid particles into the metal bowl.
The automatic drain clears condensate without manual attention, suited for wet lines or unattended operation. The pressed-in self-locking knob resists drift from vibration, while the balanced regulator keeps the set pressure stable as supply varies. Weighing 290 g, this compact body fits tight machine spaces, and the gauge connection is 1/8in if you add a gauge later.

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 GAFR200C08ALJN Is Used
Small jig clamping
Feed a single pneumatic clamp on a bench fixture with clean, regulated air at up to 0.4 MPa, using the automatic drain to avoid daily checks.
Lab air supply
Provide a steady low-pressure air source for a test rig or sensitive instrument, where the 40 um filter protects orifices and the compact body saves bench space.
Maintenance cart
Mount on a service cart to supply filtered, regulated air for portable tools, with the metal bowl resisting knocks during movement.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJN the Right Air-Prep Unit?
Choose the GAFR200 body for small jigs or single actuators with 1/4in ports; step up to a GAFR300 (60 cc bowl, plotted to 3500 L/min at 0.7 MPa inlet) if you need more condensate capacity. The metal bowl suits demanding environments, though the -5 to 70 C limit applies to all materials, so confirm compatibility for aggressive surroundings. This model has an automatic drain, no mounting bracket (J), and no gauge fitted, so plan for panel mounting and a separate gauge if you need to read pressure. The 40 um element handles general shop air, while the L-type range tops out at 0.4 MPa, so verify your supply never needs more. For oil downstream, order the matching GAFC200-08 combination instead. 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 GAFR200C08ALJN FAQ
The 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). Temperature range is -5 to 70 C, the drain bowl holds 25 cc, and the unit weighs 290 g. It has a 1/4in port, 40 um element, automatic drain, and no gauge.
The J code omits the mounting bracket for panel-mount or existing fixtures, and the N code means no gauge is supplied. The gauge connection is 1/8in if you add one later, but you cannot read the set pressure without fitting a gauge.
