Airtac GAFR Adjustable Filter Regulator GAFR40015ASJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJN 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 GAFR40015ASJN
The GAFR40015ASJN is a filter & regulator that combines a 40 um air filter and a pressure regulator in a single body, saving rail space and reducing potential leak points compared to separate units. This 1/2in model operates from 0.15 to 0.9 MPa (20-130 psi) and features an automatic drain that ejects condensate without manual attention.
The balanced regulator mechanism holds the outlet pressure steady as the supply varies, while the pressed-in self-locking knob resists drift from vibration. With a 100 cc drain bowl and 880 g mass, this unit is sized for medium-flow lines and needs a proper panel or frame mount rather than support from the tubing.

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 GAFR40015ASJN Is Used
Machine tool coolant lines
Feed a 1/2in line supplying coolant valves and actuation cylinders on a CNC lathe or mill, where steady pressure and clean air prevent erratic tool changes.
Assembly station headers
Supply a multi-operator workbench with filtered, regulated air for pneumatic screwdrivers and push-in fittings, with the automatic drain reducing maintenance on busy shifts.
Packaging equipment air prep
Protect indexing cylinders and grippers on a carton erector or strapping machine from water and particulates, while the self-locking knob holds the setpoint through line vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJN the Right Air-Prep Unit?
Choose the GAFR400 body for 1/2in porting and a 7000 L/min flow envelope plotted at 0.7 MPa inlet. The automatic drain (A) suits unattended or wet lines, while the omitted bracket (J) indicates a panel-mount or existing bracket installation. No gauge is supplied with this model; the 1/4in gauge connection allows adding one later if readout is needed. The 40 um element handles general workshop air, and the PT thread with MPa/psi scale matches common regional fittings. If the line needs oil 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 GAFR40015ASJN FAQ
This filter & regulator has a 1/2in port, a working 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 from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g. The 40 um element filters solid particles and liquid water.
The J code means the mounting bracket is omitted, which is intended for installations using an existing bracket or a direct panel mount. The 1/4in gauge connection is still available if you need to add a pressure gauge later. This unit should be rigidly mounted given its 880 g weight.
