Airtac GAFR Adjustable Filter Regulator GAFR30010ASJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30010ASJWK 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 GAFR30010ASJWK
The GAFR30010ASJWK is a filter and pressure regulator combined into a single body, eliminating the need for separate GAF and GAR units. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator mechanism.
This model has a 3/8in port, a 60 cc condensate bowl, and weighs 500 g. It operates in the standard 0.15-0.9 MPa (20-130 psi) range with a 5 um element for finer filtration. The automatic drain handles condensate without manual intervention, and the included circular gauge shows MPa/psi.

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 GAFR30010ASJWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at a stable pressure. The 5 um element protects sensitive internals from fine particulate.
Machine tool air supply
Supply a CNC machine's air circuit where consistent pressure is critical for tool clamping and actuation. The automatic drain keeps the bowl from filling during long runs.
Test bench setup
Power a pneumatic test fixture that requires a clean, regulated air source. The compact 500 g body mounts easily on a panel or frame.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30010ASJWK the Right Air-Prep Unit?
Choose the GAFR300 body for medium-flow lines; its 3500 L/min plotted flow envelope at 0.7 MPa inlet sits between the smaller GAFR200 and larger GAFR400. The PC bowl suits general industrial use, while the 5 um element traps finer particles for sensitive equipment. The automatic drain (A) suits unattended operation, and the J code means no mounting bracket is included. The fitted gauge reads MPa/psi with PT threads, and the K code adds a reverse-flow valve. For lines needing lubrication downstream, order the matching GAFC300-10 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated 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 GAFR30010ASJWK FAQ
It operates from 0.15 to 0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The K code indicates a reverse-flow (reflux) valve is fitted to the unit. This is an ordering difference from models without the K code. The function of the valve is detailed in the full catalogue.
