Airtac GAFR Adjustable Filter Regulator GAFR400C15ASK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C15ASK 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 GAFR400C15ASK
The GAFR400C15ASK is a filter and regulator combined in one body, so it cleans the air and stabilizes outlet pressure without needing separate units. It has a 1/2in port, a 100 cc metal condensate bowl, and weighs 880 g, placing it in the mid-size class for shop air lines.
This model operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 40 um element. The circular gauge with MPa/psi scale is fitted, and the automatic drain handles condensate without manual attention. A reverse-flow valve is attached as an ordering option.

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 GAFR400C15ASK Is Used
Machine tool lines
Feed a CNC machine's air cylinders and valves with filtered, regulated air at a steady 0.15-0.9 MPa. The 1/2in port handles the demand of a single machine tool.
Assembly stations
Supply a multi-station assembly bench where each fixture needs clean air and consistent pressure for pneumatic clamps. The automatic drain keeps the line running through a full shift.
Test benches
Use it on a test bench that checks pneumatic components, where a stable regulated supply is essential. The 40 um element protects sensitive test instruments from particles.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C15ASK the Right Air-Prep Unit?
Choose the GAFR400 body when you need 1/2in ports and a 100 cc drain bowl, which holds about 1.7x the condensate of the GAFR300's 60 cc bowl. The metal bowl suits demanding environments, and the automatic drain is ideal for unattended operation. The standard pressure type covers 0.15-0.9 MPa, and the included bracket simplifies mounting. With the 40 um element and PT threads, this unit is ready for general pneumatic lines; if oil is needed downstream, order the matching GAFC400-15 combination instead. Remember that 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 GAFR400C15ASK FAQ
The GAFR400C15ASK is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.9 MPa (20-130 psi), max pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g. The element is 40 um, and the bowl is metal.
The K code indicates that a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference from standard models; the valve's function is detailed in the catalogue but not in our data. This model also includes an automatic drain and a metal bowl.
