Airtac GAFR Adjustable Filter Regulator GAFR40015ASN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASN 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 GAFR40015ASN
The GAFR40015ASN is a filter and regulator combined into a single body, eliminating the need for a separate filter and regulator pair. This 1/2in port unit weighs 880 g and handles a standard pressure range of 0.15-0.9 MPa (20-130 psi), filtering incoming air with a 40 um element before regulating the outlet.
Its diversion structure spins the air to separate liquid water and solid particles into the 100 cc condensate bowl, while the balanced regulator mechanism holds the set pressure steady as supply varies. With an automatic drain, this model requires no manual intervention for condensate removal, and the included mounting bracket simplifies installation on panels or frames.

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 GAFR40015ASN Is Used
Precision machining center
Feed a 1/2in line to a CNC machine's pneumatic clamping system, where the 40 um filter protects precision valves and the regulator holds a stable 0.5 MPa for consistent clamping force.
Assembly line automation
Supply a multi-station assembly fixture with filtered, regulated air at 0.6 MPa, using the automatic drain to handle condensate from a humid plant air system without daily maintenance.
Test bench air supply
Provide clean, regulated air at 0.3 MPa to a pneumatic test bench, where the 100 cc bowl and automatic drain keep the line free of water between test cycles.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASN the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 1/2in port and a 100 cc drain bowl, stepping up from the GAFR300's 60 cc bowl if your line needs fewer drain interventions. This model has a PC bowl, a 40 um element, and an automatic drain (A) for wet or unattended lines; the standard pressure type (S) covers 0.15-0.9 MPa (20-130 psi). The mounting bracket is included, but no gauge is fitted (N) - the 1/4in gauge connection allows adding one later, and the PT thread gives an MPa/psi scale. If your application needs lubrication 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, so plan your inlet pressure near 1.0 MPa if you intend to set the regulator at its maximum.
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 GAFR40015ASN FAQ
The GAFR40015ASN is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.9 MPa (20-130 psi), and a maximum pressure of 1.0 MPa (145 psi). Proof pressure is 1.5 MPa (215 psi), and the operating temperature range is -5 to 70 C. It has a 100 cc drain bowl, weighs 880 g, and uses a 40 um filter element with an automatic drain.
The 'N' in the model code means no gauge is supplied, which suits installations where a panel-mounted gauge already exists or where remote pressure monitoring is used. The GAFR400 has a 1/4in gauge connection port, so you can add an AirTAC gauge later if you need to read the set pressure locally.
