Airtac GAFR Adjustable Filter Regulator GAFR40015ASJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJK 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 1/2" 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 GAFR40015ASJK
The GAFR40015ASJK is a filter & regulator from AirTAC, combining both functions in a single body. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator. This unit has no lubricator and only one bowl, the 100 cc condensate bowl.
This model uses a 1/2in port, operates from 0.15 to 0.9 MPa (20-130 psi), and comes with a 40 um element. The pressed-in self-locking knob resists set-pressure drift from vibration, making it a stable choice for industrial lines. It weighs 880 g, so it needs a proper panel or frame mount rather than support from the tubing.

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 GAFC400-15 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 GAFR40015ASJK Is Used
Machine Tool Feed
Feed a single machining center's pneumatic controls with stable pressure, using the automatic drain to handle condensate from a wet shop line.
Assembly Station
Supply a multi-fixture assembly station where the 1/2in port supports several actuators, and the self-locking knob keeps the setpoint steady despite nearby vibration.
Test Rig Air Supply
Provide filtered, regulated air to a test rig with a 40 um element, ensuring solid particles are trapped before reaching sensitive gauges or valves.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJK the Right Air-Prep Unit?
Choose the GAFR400 body for a 1/2in port with a 100 cc drain bowl, stepping up from the GAFR300's 60 cc bowl for longer intervals between drains. The PC bowl (blank code) is a build choice; confirm compatibility for aggressive surroundings since no chemical data is printed. This model has an automatic drain (A), so it suits unattended or wet lines without manual intervention. The standard type (S) covers 0.15-0.9 MPa, and the 40 um element is the default. A bracket is not included (J), so plan for panel mounting or an existing bracket. The fitted gauge reads MPa/psi on the PT thread scale, and the reverse-flow (reflux) valve (K) is attached as an ordering difference. If the line needs oil downstream, order the matching GAFC400-15 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa for a 0.9 MPa setpoint.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 880 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 GAFC400-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40015ASJK FAQ
The GAFR40015ASJK is a filter & regulator with a 1/2in 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 must not freeze. The drain bowl holds 100 cc, and the unit weighs 880 g. It has a 40 um element and an automatic drain.
The K code indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference that adds the valve to the unit. The catalogue does not detail its function in our data, so treat it as a specified option for your application.
