Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNK 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 GAFR20008ALJNK
The GAFR20008ALJNK is a filter and regulator combined into a single body, so it cleans incoming air and stabilizes outlet pressure without needing a separate filter plus regulator pair. This compact unit uses a 1/4in port, weighs 290 g, and has a 25 cc condensate bowl that collects the water and solids spun out by its diversion structure.
This lower-pressure version regulates from 0.15 to 0.4 MPa (20-58 psi) with a 40 um element, making it suitable for gentle, consistent air delivery. It features an automatic drain that expels collected liquid without manual intervention, and it comes without a bracket or gauge, so you can mount it directly and read pressure with your own instrument.

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 GAFR20008ALJNK Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a small assembly fixture with clean, regulated air. The 40 um filter protects the clamp's seals, while the lower pressure range prevents over-forcing delicate parts.
Bench-Mounted Air Tool
Supply a small air screwdriver or grinding tool on a workbench. The compact 290 g body mounts directly to the tool's inlet, and the automatic drain keeps condensate from reaching the tool during light use.
Lab Air Supply
Provide stable, filtered air to a laboratory instrument that needs gentle pressure. The 0.15-0.4 MPa range is ideal for sensitive experiments, and the 25 cc bowl is easy to inspect between runs.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNK the Right Air-Prep Unit?
Choose the GAFR200 for small jigs or single actuators where a 1/4in port and 290 g weight fit tight spaces. The automatic drain (A) handles wet lines or unattended operation, while the missing bracket (J) suits panel-mount or existing hardware. Since there is no gauge (N), the 1/8in gauge connection is ready for your own pressure display. The lower-pressure type (L) tops out at 0.4 MPa, so verify your system never needs more than that. The reverse-flow valve (K) is fitted as an ordering difference. If you need lubrication downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa regulated ceiling.
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 GAFR20008ALJNK FAQ
The GAFR20008ALJNK is a filter and regulator with a 1/4in port, a 25 cc drain bowl, and a weight of 290 g. It regulates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The operating temperature range is -5 to 70 C, and it uses a 40 um filter element.
The 'N' after the port code means no gauge is supplied, so you can connect your own to the 1/8in gauge port. The 'J' means the mounting bracket is omitted, which is useful when you are panel-mounting the unit or using an existing bracket. This reduces initial cost and lets you customize the installation.
