Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNK 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 GAFR40015ASJNK
The GAFR40015ASJNK is a filter and regulator combined into a single body, handling both air preparation tasks without the need for a separate filter and regulator pair. It delivers a steady outlet pressure from 0.15-0.9 MPa (20-130 psi) and filters particulates down to 40 um, with its 100 cc condensate bowl capturing separated water and solids.
This 1/2in port unit weighs 880 g, placing it in the mid-range size class where it requires a proper panel or frame mount rather than support from the tubing. The automatic drain (A) clears collected condensate without manual intervention, while the reverse-flow (reflux) valve (K) is fitted as an ordering difference. No gauge is supplied; the 1/4in gauge connection allows for later addition.

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 GAFR40015ASJNK Is Used
Machine tool circuits
Feed a steady 0.15-0.9 MPa supply to a CNC machine's pneumatic clamping system, where the 40 um filter protects precision valves and the automatic drain reduces maintenance stops.
Assembly line stations
Supply filtered, regulated air to a multi-station assembly line with 1/2in piping, using the 100 cc bowl to handle condensate between scheduled line shutdowns.
Test bench air supply
Provide a clean, stable air source for a pneumatic test bench with multiple actuators, relying on the balanced regulator to hold set pressure as the shop supply fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJNK the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow applications needing a 1/2in port, positioned between the smaller GAFR300 (60 cc bowl, 3500 L/min plotted at 0.7 MPa inlet) and the larger GAFR500 (108 cc bowl, 8000 L/min plotted at 0.7 MPa inlet). The PC bowl suits general-purpose use, while the automatic drain (A) handles unattended or wet lines; the omitted bracket (J) suits panel-mount installations. The standard type (S) covers 0.15-0.9 MPa, the 40 um element is the default grade, and the PT thread pairs with an MPa/psi gauge scale. 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 GAFR40015ASJNK FAQ
Working pressure range 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. It has a 1/2in port, 40 um element, and automatic drain.
The J code omits the mounting bracket for panel-mount or existing bracket installations, and the N code means no gauge is supplied. The 1/4in gauge connection remains available if you add a gauge later. The reverse-flow (reflux) valve (K) is fitted as an ordering difference.
