Airtac GAFR Adjustable Filter Regulator GAFR40015SJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015SJN 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 GAFR40015SJN
The GAFR40015SJN is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and a 40 um filter element.
This 880 g unit uses a diversion structure to spin incoming air, separating liquid water and solid particles into a 100 cc drain bowl. The balanced regulator mechanism helps maintain a steady outlet pressure as supply varies, and the pressed-in self-locking knob resists drift from vibration.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR400 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR40015SJN Is Used
Machine tool air prep
Feed a clean, regulated 1/2in air supply to a CNC machine's tool changer or clamping fixtures, where stable pressure supports consistent operation.
Assembly line stations
Provide filtered air at a set pressure to multiple pneumatic actuators on a medium-sized assembly station, with the 100 cc bowl reducing drain frequency.
Test bench supply
Supply a controlled air pressure to a laboratory test jig or calibration rig, where the 40 um element helps protect sensitive valves and instruments.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015SJN the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow applications needing a 1/2in port; its flow curve is plotted to 7000 L/min at 0.7 MPa inlet, a step up from the GAFR300's 3500 L/min envelope. This model has a PC bowl, a semi-auto drain plus manual drain, and no mounting bracket (J), so plan for panel mounting or an existing bracket. The 40 um element is standard; the gauge is omitted (N), but the 1/4in gauge connection is ready for an add-on. If oil is needed downstream, order the matching GAFC400-15 combination instead. 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 GAFR40015SJN FAQ
This filter & regulator has a 1/2in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g.
The 'N' code means no pressure gauge is supplied with the unit. The GAFR400 body has a 1/4in gauge connection, so you can add a compatible gauge later if you need to read the outlet pressure directly on the unit.
