Airtac GAFR Adjustable Filter Regulator GAFR30010SJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010SJW 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 5 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 GAFR30010SJW
The GAFR30010SJW is a filter and regulator combined into a single body, saving space and reducing potential leak points compared to separate units. It filters incoming air through a diversion structure that spins out liquid water and solid particles, then regulates the outlet pressure with a balanced, self-locking mechanism that resists drift from vibration.
This model has a 3/8in port and a working pressure range of 0.15-0.9 MPa (20-130 psi). It is fitted with a 5 um filter element for finer particle removal, a circular gauge with an MPa/psi scale, and both semi-auto and manual drains. The 60 cc condensate bowl and 500 g weight define its size class, requiring a proper panel or frame mount rather than support from the tubing.

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 GAFR30010SJW Is Used
Precision Valve Control
Feed a bank of precision pneumatic valves that require clean, regulated air. The 5 um element traps fine particles that could clog small orifices, while the balanced regulator holds the set pressure steady as line supply varies.
Machine Tool Air Supply
Supply a single machining center or assembly station with filtered, regulated air. The 3/8in port and 60 cc condensate bowl handle typical tool air consumption, and the semi-auto drain lets operators clear water during shift changes.
Test Bench Air
Provide consistent air pressure to a laboratory or quality-control test bench. The circular gauge with MPa/psi scale allows operators to verify set pressure at a glance, and the self-locking knob prevents drift from bench vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010SJW the Right Air-Prep Unit?
Choose the body and port size based on your flow and piping needs: the GAFR300 with its 3/8in port is a mid-range option, while the smaller GAFR200 (plotted to 2000 L/min at 0.7 MPa inlet) suits lighter duty, and the larger GAFR400 (plotted to 7000 L/min at 0.7 MPa inlet) handles higher flow. This model uses a PC bowl, which is a build choice; metal (C) and nylon (N) bowls are available on other codes, but confirm compatibility for aggressive environments. The drain is semi-auto plus manual, meaning it can be drained manually or automatically when pressure drops; the A code specifies a fully automatic drain for unattended lines. The S type provides the standard 0.15-0.9 MPa range, while the L type tops out at 0.4 MPa for lower-pressure applications. This unit ships without the mounting bracket (J code), so plan for a panel mount or use an existing bracket. A circular gauge is fitted, reading MPa/psi on the PT thread; the G code changes the thread to G with a bar/MPa scale, and T changes to NPT with a psi/bar scale. The 5 um element (W) traps finer particles than the standard 40 um, but requires more frequent service. If lubrication is needed downstream, order the matching GAFC300-10 combination instead, as this unit does not lubricate. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure near 1.0 MPa to achieve the highest setpoint.
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 GAFR30010SJW FAQ
The GAFR30010SJW is a filter & regulator with a 3/8in port. Its working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum 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. It has a 5 um filter element, a 60 cc condensate bowl, and weighs 500 g.
The J code means the mounting bracket is not included. This unit is designed for panel mounting or for use with an existing bracket. It should not be supported by the air tubing alone, as the 500 g weight requires a secure mounting point.
