Airtac GAFR Adjustable Filter Regulator GAFR40015SNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015SNW 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 GAFR40015SNW
The GAFR40015SNW is a filter and pressure regulator combined into a single body, so incoming air is spun to separate liquid water and solid particles before a balanced regulator sets a steady outlet pressure. This 1/2in unit works in the 0.15-0.9 MPa (20-130 psi) range and uses a 5 um element for finer filtration.
With no gauge fitted, the 1/4in gauge connection is ready for an add-on if you need to read the set pressure. The 880 g body with its 100 cc condensate bowl suits a machine header or multi-station line, and the included mounting bracket keeps the unit supported without relying on 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 GAFR40015SNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at a steady pressure. The 5 um element removes fine particles that could clog small orifices, while the balanced regulator holds the outlet steady as the supply varies.
Machine header supply
Mount this unit on a machine header to supply a multi-station assembly line. The 100 cc condensate bowl handles moisture from a wet line, and the included bracket secures the 880 g body to the frame.
Test rig air supply
Use it on a test bench where you need a clean, regulated air source for fixtures and actuators. The semi-auto drain releases condensate automatically while the manual drain lets you check bowl condition between runs.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015SNW the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 1/2in port and a 100 cc drain bowl; step up to the GAFR500 for a 3/4in port with a 108 cc bowl and an 8000 L/min flow envelope at 0.7 MPa inlet. The PC bowl is the standard build, and the semi-auto plus manual drain gives you both automatic condensate release and a manual override. The 5 um element traps finer particles than the standard 40 um, which suits precision valves or instrument air but needs more frequent service. The bracket is included, and the PT thread uses an MPa/psi gauge scale; if oil is needed downstream, order the matching GAFC400-15 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the inlet pressure near the maximum to reach the highest setpoint.
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 GAFR40015SNW FAQ
The GAFR40015SNW is a filter & regulator with a 1/2in port, working pressure range 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -5 to 70 C. It has a 100 cc drain bowl, weighs 880 g, and uses a 5 um element.
The N after the port code means no gauge is supplied. The GAFR400 has a 1/4in gauge connection, so you can add a gauge later if you need to read the set pressure. Without a gauge, you cannot verify the outlet pressure visually, so plan to add one if that matters for your process.
