Airtac GAFR Adjustable Filter Regulator GAFR400N15SWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400N15SWK 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 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 GAFR400N15SWK
The GAFR400N15SWK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 1/2in port model handles 0.15-0.9 MPa (20-130 psi) and comes with a 5 um element for finer filtration of solid particles and liquid water.
Its 100 cc nylon condensate bowl collects what the diversion structure spins out, while the balanced regulator holds outlet pressure steady as supply varies. The pressed-in self-locking knob resists drift from vibration, and the included circular gauge shows the set pressure on an MPa/psi scale.

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 GAFR400N15SWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a machining center where the 5 um element protects tight clearances from fine abrasive dust.
Medium assembly line
Supply a multi-station assembly fixture with stable 0.15-0.9 MPa air, using the 100 cc bowl to reduce drain checks compared to smaller bodies.
Test bench air
Provide clean, regulated air to a laboratory test bench where the included gauge lets operators verify set pressure at a glance.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400N15SWK the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow lines; its 7000 L/min plotted flow envelope at 0.7 MPa inlet sits between the GAFR300's 3500 L/min and the GAFR500's 8000 L/min. The nylon bowl suits applications where a metal bowl is overkill and PC might be a concern, though confirm compatibility for aggressive surroundings since all materials share the same 1.0 MPa max and -5 to 70 C rating. This model ships with both semi-auto and manual drains, includes the mounting bracket, and has the 5 um element fitted for finer particle removal. The PT thread carries an MPa/psi gauge scale, and the K code adds the reverse-flow (reflux) valve as an ordering difference. If oil is needed downstream, order the matching GAFC400-15 combination instead. Max supply 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near 1.0 MPa for full regulated output.
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 GAFR400N15SWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g with a 1/4in gauge connection.
The K indicates a reverse-flow (reflux) valve is fitted. It appears as a separate pneumatic symbol in the catalogue and is an ordering difference; its detailed function is covered on a page not included in our data.
