Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJK 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 GAFR400C15ASJK
The GAFR400C15ASJK is a filter and regulator combined into a single body, so it cleans incoming air and sets a steady outlet pressure without needing a separate filter plus regulator pair. This 1/2in model handles flows plotted to 7000 L/min at 0.7 MPa inlet and weighs 880 g, placing it in the mid-size class for machine headers. It has a metal bowl, a 40 um element, and an automatic drain, with a working range of 0.15-0.9 MPa (20-130 psi). No lubricator is present, and this unit has only one bowl for condensate.
The balanced regulator mechanism holds the set pressure steady as supply varies, and the pressed-in self-locking knob resists drift from vibration. The diversion structure spins the air to separate liquid water and solid particles into the 100 cc drain bowl. This model ships without a mounting bracket, so plan for a panel mount or an existing bracket. A reverse-flow valve is fitted as an ordering option, and the circular gauge reads in 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 GAFR400C15ASJK Is Used
Machine tool header
Feed a 1/2in header serving several pneumatic actuators on a CNC machine. The 100 cc bowl and automatic drain handle condensate from a busy shift without manual attention.
Assembly line station
Supply a multi-station assembly line where a steady 0.15-0.9 MPa (20-130 psi) is needed for clamping fixtures. The metal bowl resists rough handling near the line.
Test bench air supply
Provide filtered air to a test bench with precision valves. The 40 um element traps particles, and the self-locking knob keeps the set pressure stable during vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJK the Right Air-Prep Unit?
Choose this GAFR400 body when your line needs a 1/2in port and the flow envelope plotted to 7000 L/min at 0.7 MPa inlet. Compared to a GAFR300 with its 3500 L/min envelope, this unit doubles the sizing capacity for a growing machine header. The metal bowl is a build choice, and the common pressure and temperature specs are identical across bowl materials. The automatic drain suits wet or unattended lines, while the standard type covers 0.15-0.9 MPa (20-130 psi). The J code means no bracket is included, and the K code adds a reverse-flow valve. If oil is needed downstream, order the matching GAFC400-15 combination instead. 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 (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 GAFR400C15ASJK FAQ
The 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 temperature range is -5 to 70 C and it must not freeze. The drain bowl capacity is 100 cc, and the unit weighs 880 g. The port is 1/2in, and the flow curve is plotted to 7000 L/min at 0.7 MPa inlet.
The K code indicates a reverse-flow (reflux) valve is fitted to the GAFR400C15ASJK. This is an ordering difference from models without the K code. The catalogue does not detail its function in our data, so treat it as a specified option for your application.
