Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJNW 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 GAFR300C15ASJNW
This AirTAC GAFR300C15ASJNW is a filter and regulator combined into a single body, so it cleans incoming air and stabilizes outlet pressure without needing separate components. It has a 1/2in port, a 0.15-0.9 MPa (20-130 psi) working range, and a 5 um filter element for trapping fine particles.
The metal bowl holds 60 cc of condensate and uses an automatic drain for unattended operation. Weighing 500 g, this unit replaces a separate filter plus regulator, reducing potential leak points and saving space on the rail.

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 GAFR300 is 1/8" 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 GAFC300-15 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 GAFR300C15ASJNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves with 5 um filtered air at a stable 0.15-0.9 MPa, protecting fine internal orifices from particle wear.
Machine tool air supply
Supply a single machine tool's clamping circuit with cleaned, regulated air from a compact 500 g unit that mounts directly on the machine frame.
Automated assembly station
Provide consistent actuation pressure to a multi-axis assembly station, with the automatic drain removing condensate without stopping production.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJNW the Right Air-Prep Unit?
Choose this GAFR300 body for 1/2in porting, sitting between the smaller GAFR200 and larger GAFR400 in capacity. The metal bowl is selected for demanding environments, while the 5 um element suits precision applications that need finer filtration than the standard 40 um. An automatic drain handles wet lines without manual attention, and the absence of a bracket means you will mount it on an existing panel or frame. No gauge is fitted, but the 1/8in gauge connection allows adding one later. The PT thread matches common local fittings. If your line needs oil downstream, order the GAFC300-15 combination instead, which adds a lubricator. 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJNW FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The N code after the port means no gauge is supplied, though the 1/8in connection is ready for one. The J code omits the mounting bracket, intended for installations using an existing panel mount or frame. Both options reduce cost when the standard accessories are not needed.
