Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNW 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 GAFR40015ASJNW
The GAFR40015ASJNW is a filter and regulator combined into a single body, handling both air preparation steps without needing separate units. This 1/2in version weighs 880 g and uses a 5 um element to trap fine particles before the balanced regulator stabilizes outlet pressure.
Its automatic drain clears condensate from the 100 cc bowl without manual attention, and the standard pressure range spans 0.15-0.9 MPa (20-130 psi). The PT thread option pairs with a MPa/psi gauge scale, though this model ships without a gauge for panel-mount installations.

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 GAFR40015ASJNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that require 5 um filtration to prevent fine particle wear, with the automatic drain ensuring condensate never reaches sensitive components.
Machine tool circuits
Supply a 1/2in manifold on a CNC machine or press, where the 100 cc bowl handles typical condensate loads and the balanced regulator holds setpoint as shop air pressure fluctuates.
Panel-mount retrofit
Replace a separate filter and regulator pair on an existing panel, using the included bracket holes (bracket omitted here) and adding a gauge through the 1/4in port for local pressure readout.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNW the Right Air-Prep Unit?
Choose this GAFR400 for 1/2in piping where the 100 cc drain bowl and 880 g mass suit a fixed machine installation. The automatic drain handles wet lines or unattended operation, while the 5 um element serves precision valves that need finer filtration than the standard 40 um grade. This version omits the mounting bracket (J) and gauge (N), so plan for an existing bracket and add a gauge via the 1/4in connection if readout is needed. The PT thread matches MPa/psi gauge scales, and the standard S type covers 0.15-0.9 MPa (20-130 psi). For lines needing oil downstream, order the matching GAFC400-15 combination instead. Note 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 GAFR40015ASJNW FAQ
This filter & regulator has a 1/2in port, 0.15-0.9 MPa (20-130 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, and -5 to 70 C temperature range. The drain bowl holds 100 cc, the unit weighs 880 g, and the 5 um element filters solid particles.
The J code omits the mounting bracket for installations using existing panel mounts or custom frames, while the N code removes the gauge for applications where pressure is monitored elsewhere. The 1/4in gauge connection remains available if you add a gauge later.
