Airtac GAFR Adjustable Filter Regulator GAFR30010LK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010LK 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 3/8" 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 GAFR30010LK
The GAFR30010LK is a filter & regulator with the filter and regulator combined in one body, so it replaces a separate GAF filter plus a GAR regulator and eliminates two potential leak points. This 3/8in port unit weighs 500 g and carries a 60 cc condensate bowl, with a 40 um element and a lower-pressure range of 0.15-0.4 MPa (20-58 psi).
The diversion structure spins the incoming air to separate liquid water and solid particles into the bowl, while the balanced, self-locking regulator holds the set outlet pressure steady as supply pressure varies. A circular gauge with MPa/psi scale is fitted, and the reverse-flow (reflux) valve is attached as an ordering difference.

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 GAFC300-10 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 GAFR30010LK Is Used
Precision pressure setting
Set a stable 0.3 MPa supply for a small indexing table or a single pneumatic clamp, where the lower-pressure range gives fine adjustment and the self-locking knob resists drift from machine vibration.
Compact machine build
Mount this 500 g unit on a panel or frame to feed a dedicated 3/8in line to a pick-and-place arm, using the included bracket for a clean installation that does not stress the tubing.
Wet air separation
Use the diversion filter to spin out liquid water from a humid compressor line before the air reaches a sensitive regulator, with the 60 cc bowl capturing condensate between manual drain checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010LK the Right Air-Prep Unit?
Choose the GAFR300 body for 3/8in porting with a flow curve plotted to 3500 L/min at 0.7 MPa inlet, which sits above the GAFR200's 2000 L/min envelope for larger jigs or small machine headers. The PC bowl is the standard build, and this model includes the mounting bracket, a 40 um element, and a semi-auto plus manual drain for routine service. The L type caps the regulated output at 0.4 MPa, so confirm your actuators never need more than that; the fitted gauge reads MPa/psi with PT threads, and the K code adds the reverse-flow valve. If oil is needed downstream, order the matching GAFC300-10 combination instead of this unit. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30010LK FAQ
This filter & regulator has a 3/8in port, a pressure range of 0.15-0.4 MPa (20-58 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, uses a 40 um element, and has a 60 cc drain bowl with a total weight of 500 g.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFR30010LK. It is an ordering difference from the standard unit; the catalogue does not detail its function in our data, so treat it as a specified option for your application.
