Airtac GAFR Adjustable Filter Regulator GAFR30010ALJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ALJN 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 GAFR30010ALJN
The GAFR30010ALJN is a filter and pressure regulator combined into a single body, saving space and reducing potential leak points compared to separate units. It handles 3/8in ports and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi) with a 40 um filter element.
This model features an automatic drain that expels condensate without manual intervention, making it suitable for wet or unattended lines. The 60 cc drain bowl and 500 g weight define its size class, and the absence of a gauge means the 1/8in gauge connection is available if you need to add one 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 GAFR300 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 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 GAFR30010ALJN Is Used
Precision pressure setting
Set a stable 0.15-0.4 MPa supply for sensitive pneumatic controls or low-pressure actuation circuits where precise regulation matters.
Wet utility lines
The automatic drain handles condensate in humid plant air, reducing maintenance checks on a 3/8in drop line feeding a single machine station.
Compact machine builds
With no bracket and no gauge, this unit fits tight panels where you mount it directly and read pressure from a remote or inline gauge.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010ALJN the Right Air-Prep Unit?
Choose the GAFR30010ALJN when you need a compact filter-regulator for a 3/8in line with a lower pressure ceiling of 0.4 MPa. This unit omits the mounting bracket (J code) for panel-mount installations, and the automatic drain (A code) handles condensate removal automatically. The PC bowl is the standard choice, and the 40 um element suits general-purpose filtration. If you need finer filtration, select the W option for a 5 um element. For lines requiring lubrication downstream, order the matching GAFC300-10 combination instead. Note that 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, providing ample inlet pressure for stable regulation.
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 GAFR30010ALJN FAQ
The GAFR30010ALJN operates from 0.15-0.4 MPa (20-58 psi) with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 60 cc drain bowl, weighs 500 g, uses a 40 um element, and features an automatic drain.
The J code omits the mounting bracket for installations that use existing panel mounts or machine frames. The N code (after the port) means no gauge is supplied; the 1/8in gauge connection remains available if you add one later. These options reduce cost and component count when they are not needed.
