Airtac GAFR Adjustable Filter Regulator GAFR30010ASJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ASJ 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30010ASJ
The GAFR30010ASJ is a filter and pressure regulator combined in a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 3/8in port with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and uses a 40 um filter element.
This model features an automatic drain and a clear PC bowl, with a 60 cc condensate capacity. The 500 g weight indicates a compact unit suitable for direct mounting on machinery, though the bracket is omitted (J code) for panel-mount installations.

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 GAFR30010ASJ Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp or fixture with clean, regulated air. The 40 um filter protects the valve and actuator, while the regulator holds a steady pressure for consistent clamping force.
Lab Air Supply
Provide filtered, regulated air to a laboratory bench or test setup. The automatic drain ensures the 60 cc bowl never overflows during extended experiments, and the compact 500 g body mounts easily on a frame.
Machine Tool Air Feed
Supply a small machine tool or workholding device. The combined filter-regulator simplifies the air prep zone, and the clear PC bowl allows quick visual checks of condensate levels.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010ASJ the Right Air-Prep Unit?
Choose this GAFR300 for 3/8in piping where you need both filtration and pressure control in one compact body. The automatic drain (A) handles condensate without manual intervention, ideal for wet or unattended lines. The PC bowl is the standard choice; consider the metal (C) or nylon (N) bowl options for different environments. The standard pressure type (S) covers 0.15-0.9 MPa, while the L type tops out at 0.4 MPa for low-pressure applications. This model omits the mounting bracket (J), so plan for panel mounting or an existing bracket. The fitted gauge reads in MPa/psi with PT threads. For 5 um filtration, add the W code. If downstream lubrication is required, order the matching GAFC300-10 combination instead. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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 GAFR30010ASJ FAQ
The GAFR30010ASJ is a filter & regulator with a 3/8in port. Its pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and has a 60 cc drain bowl. The unit weighs 500 g and comes with a 40 um element and automatic drain.
The J code in GAFR30010ASJ means the mounting bracket is omitted. This is for installations where the unit will be panel-mounted or attached to an existing bracket structure. If you need the standard bracket, order the model without the J code, such as GAFR30010AS.
