Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJNW 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 GAFR400C15ASJNW
The GAFR400C15ASJNW is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 1/2in version handles 0.15-0.9 MPa (20-130 psi) with a 5 um element that traps fine particles for sensitive equipment.
Its metal bowl and automatic drain make it suitable for industrial lines where condensate accumulates quickly. The 100 cc drain bowl and 880 g weight place it in the mid-size class, requiring proper panel mounting rather than tubing support.

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.

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 GAFR400C15ASJNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves requiring clean, regulated air at 5 um filtration for consistent actuation.
Machine tool circuits
Supply a CNC machine's clamping and tool-change circuits where automatic condensate removal prevents downtime.
Assembly line stations
Power multiple assembly fixtures on a conveyor line, using the 100 cc bowl to handle moisture from high-humidity plants.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C15ASJNW the Right Air-Prep Unit?
Choose the GAFR400 body when you need 1/2in ports with a 7000 L/min flow envelope at 0.7 MPa inlet, stepping up from the GAFR300's 3500 L/min for larger actuator banks. The metal bowl (C) suits demanding environments while the automatic drain (A) removes condensate without manual attention. This model omits the bracket (J) for panel mounting and has no gauge (N), but the 1/4in gauge connection allows adding one later. The 5 um element (W) provides finer filtration than the standard 40 um, though it requires more frequent service. With PT threads and no reflux valve, this configuration fits standard installations. If oil lubrication is needed downstream, order the GAFC400-15 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near maximum for full regulation.
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 GAFR400C15ASJNW FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with 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 with a 1/2in port.
The N code means no gauge is supplied, saving cost when pressure is monitored elsewhere. If you add one later, the GAFR400 uses a 1/4in gauge connection, and the PT thread version reads in MPa/psi scale.
